How is the heart operated on? What are heart surgeries? Carrying out coronary artery bypass grafting

Cardiac surgery is a branch of medicine dedicated to the surgical treatment of the heart. With pathologies of the cardiovascular system, such intervention is an extreme measure. Doctors try to restore the patient's health without surgery, but in some cases only cardiac surgery can save the patient. Today, this field of cardiology uses the latest advances in science to return the patient to health and a fulfilling life.

Indications for operations

Invasive interventions on the heart is a complex and risky job, it requires skill and experience, and the patient - preparation and implementation of recommendations. Since such operations are risky, they are carried out only when absolutely necessary. In most cases, the patient is trying to rehabilitate with the help of medicines and medical procedures. But in cases where such methods do not help, heart surgery is needed. Surgical intervention is carried out in a hospital and complete sterility, the operated is under anesthesia and the control of the surgical team.

Such interventions are needed for congenital heart defects or acquired ones. The former include pathologies in the anatomy of the organ: defects in valves, ventricles, impaired blood circulation. Most often they are discovered even during the bearing of a child. Heart disease is also diagnosed in newborns, often such pathologies need to be eliminated urgently in order to save the life of the baby. Among the acquired diseases, ischemic disease is in the lead, in this case, surgery is considered the most effective method of treatment. Also in the heart area there are: impaired blood circulation, stenosis or valve insufficiency, heart attack, pericardial pathology and others.

Heart surgery is prescribed in situations where conservative treatment does not help the patient, the disease progresses rapidly and threatens life, with pathologies that require urgent and urgent correction, and in advanced forms of the disease, a late visit to the doctor.

The decision on the appointment of the operation is made by a council of doctors or. The patient must be examined to establish an accurate diagnosis and type of surgical intervention. They identify chronic diseases, stages of the disease, assess the risks, in which case they talk about a planned operation. If emergency assistance is needed, for example, when a blood clot is torn off or an aneurysm is exfoliated, minimal diagnostics are performed. In any case, the function of the heart is restored surgically, its departments are rehabilitated, blood flow and rhythm are normalized. In severe situations, the organ or its parts are no longer amenable to correction, then prosthetics or transplantation is prescribed.

Classification of heart operations

There can be dozens of different diseases in the area of the heart muscle, these are: insufficiency, narrowing of the lumen, ruptures of blood vessels, stretching of the ventricles or atria, purulent formations in the pericardium, and much more. To solve each problem, surgery has several types of operations. They are distinguished by urgency, effectiveness and method of influencing the heart.

The general classification divides them into operations:

Buried - used to treat arteries, large vessels, aorta. During such interventions, the chest of the operated person is not opened, the heart itself is also not affected by the surgeon. Therefore, they are called "closed" - the heart muscle remains intact. Instead of a strip opening, the doctor makes a small incision in the chest, most often between the ribs. Closed types include: shunting, balloon angioplasty, stenosis of blood vessels. All these manipulations are designed to restore blood circulation, sometimes they are prescribed to prepare for a future open operation.
Open - carried out after opening the sternum, sawing the bones. The heart itself during such manipulations can also be opened to get to the problem area. As a rule, for such operations, the heart and lungs must be stopped. To do this, connect the heart-lung machine - AIC, it compensates for the work of "disconnected" organs. This allows the surgeon to accurately perform the work, in addition, the procedure under the control of AIC takes longer, which is necessary when eliminating complex pathologies. During open operations, AIC may not be connected, but only the desired zone of the heart can be stopped, for example, during coronary artery bypass grafting. Opening the chest is necessary to replace valves, prosthetics, and eliminate tumors.
X-ray surgery - similar to a closed type of operation. The essence of this method is that the doctor moves a thin catheter through the blood vessels, and gets to the very heart. The chest is not opened, the catheter is placed in the thigh or shoulder. The catheter is injected with a contrast agent that stains the vessels. The catheter is advanced under X-ray control, the video image is transmitted to the monitor. Using this method, the lumen in the vessels is restored: at the end of the catheter there is a so-called balloon and a stent. At the site of narrowing, this balloon is inflated with a stent, restoring the normal patency of the vessel.

The safest are minimally invasive methods, that is, X-ray surgery and a closed type of surgery. With such work, the risk of complications is the least, the patient recovers faster after them, but they can not always help the patient. Complex operations can be avoided with periodic inspections. The earlier the problem is identified, the easier it is for the doctor to solve it.

Depending on the condition of the patient, there are:

planned operation. It is carried out after a detailed examination, within the agreed time frame. A planned intervention is prescribed when the pathology does not pose a particular danger, but it cannot be postponed.
Urgent - these are operations that need to be done in the next few days. During this time, the patient is prepared, all the necessary studies are carried out. The date is set immediately after receiving the necessary data.
Emergency. If the patient is already in serious condition, the situation may worsen at any time - an operation is prescribed immediately. Before her, only the most important examinations and preparations are carried out.

In addition, surgical care can be radical or auxiliary. The first implies the complete elimination of the problem, the second - the elimination of only part of the disease, improving the patient's well-being. For example, if a patient has a pathology of the mitral valve and stenosis of a vessel, the vessel is first restored (auxiliary), and after a while valve plastic surgery (radical) is prescribed.

How operations are done

The course and duration of the operation depends on the pathology being eliminated, the patient's condition, and the presence of concomitant diseases. The procedure can take half an hour, and can stretch for 8 hours or more. Most often, such interventions last 3 hours, are carried out under general anesthesia and AIC control. First, the patient is prescribed an ultrasound of the chest, urine and blood tests, an ECG, and a consultation with specialists. After receiving all the data, they determine the degree and place of the pathology, decide whether there will be an operation.

As part of the preparation, a low-fat, spicy, and fried diet is also prescribed. For 6-8 hours before the procedure, it is recommended to refuse food and drink less. In the operating room, the doctor assesses the well-being of the ward, introduces the patient into a medical sleep. With minimally invasive interventions, local anesthesia is sufficient, for example, during X-ray surgery. When anesthesia or anesthesia takes effect, the main actions begin.

Heart valve repair

There are four valves in the heart muscle, all of which serve as a passage for blood from one chamber to another. The most commonly operated valves are the mitral and tricuspid valves, which connect the ventricles to the atria. Stenosis of the passages occurs with insufficient expansion of the valves, while the blood does not flow well from one department to another. Valve insufficiency is a poor closure of the cusps of the passage, while there is an outflow of blood back.

Plastic surgery is carried out open or closed, during the operation, special rings or sutures are applied manually along the diameter of the valve, which restore the normal lumen and narrow the passage. Manipulations last an average of 3 hours; with open views, an AIC is connected. After the procedure, the patient remains under the supervision of doctors for at least a week. The result is normal blood circulation and functioning of the heart valves. In severe cases, native leaflets are replaced with artificial or biological implants.

Elimination of heart defects

In most cases, defects are congenital, the reason for this can be hereditary pathologies, bad habits of parents, infections and fever during pregnancy. At the same time, children may have various anatomical abnormalities in the region of the heart, often such anomalies are poorly compatible with life. The urgency and type of surgery depends on the condition of the child, but they are often prescribed as early as possible. For children, heart surgery is performed only under general anesthesia, and under the supervision of medical equipment.

At an older age, heart defects develop with defects in the interatrial septum. This happens with mechanical damage to the chest, infectious diseases, due to concomitant heart disease. To eliminate such a problem, an open operation is also needed, more often with artificial cardiac arrest.

During manipulations, the surgeon can “patch” the septum with a patch, or suture the defective part.

shunting

Coronary artery disease (CHD) is a very common pathology that affects mainly the generation over 50 years of age. Appears due to impaired blood flow in the coronary artery, which leads to oxygen starvation of the myocardium. There is a chronic form, in which the patient has constant attacks of angina pectoris, and an acute one is a myocardial infarction. They try to eliminate chronic pain conservatively or with the help of minimally invasive techniques. Acute requires urgent intervention.

To prevent complications or alleviate the disease, apply:

aorto-coronary bypass;
balloon angioplasty;
transmyocardial laser revascularization;
stenting of a coronary artery.

All these methods are aimed at restoring normal blood flow. As a result, enough oxygen is supplied to the myocardium with blood, the risk of a heart attack is reduced, and angina pectoris is eliminated.

If you need to restore normal patency, angioplasty or stenting is enough, in which the catheter is moved through the vessels to the heart. Before such an intervention, coronary angiography is performed to accurately determine the blocked area. Sometimes blood flow is restored bypassing the affected area, while a bio-shunt (often a section of the patient's own vein from the arm or leg) is sutured to the artery.

Recovery after interventions

After surgery, the patient remains in the hospital for another 1-3 weeks, all this time the doctors will assess his condition. The patient is discharged after verification and approval by the cardiologist.

The first month after surgical procedures is called the early postoperative period, at this time it is very important to follow all the doctor's recommendations: diet, calm and measured lifestyle. Nicotine, alcohol, junk food and physical activity are prohibited regardless of the type of intervention.

The doctor's recommendations should also contain a warning about the dangers and complications. At discharge, the doctor will set the date for the next appointment, but you need to seek help and unscheduled if the following symptoms occur:

sudden fever;
redness and swelling at the incision site;
discharge from the wound;
persistent chest pain;
frequent dizziness;
nausea, bloating and stool disorders;
breathing difficulties.

At scheduled examinations, the cardiologist will listen to the heartbeat, measure the pressure, and listen to complaints. To check the effectiveness of the operation, ultrasound, computed tomography, x-ray examinations are prescribed. Such visits are scheduled once a month for six months, then the doctor will see you once every 6 months.

Often, in addition to surgical care, medications are prescribed. For example, when prosthetic valves are artificially implanted, the patient drinks anticoagulants for life.

In the postoperative period, it is important not to self-medicate, since the interaction of permanent drugs and other medications can give a negative result. Even conventional painkillers need to be discussed with. To keep fit and restore health faster, it is recommended to be outdoors more often, walk on foot.

Life after heart surgery will gradually return to its previous course, a full recovery is predicted within a year.

Cardiac surgery offers many methods for the rehabilitation of the heart. Such operations are designed to restore the patient's physical and moral strength. You should not be afraid or avoid such procedures, on the contrary, the sooner they are carried out, the greater the chances of success.

But now, the diagnosis has been made and the doctors understand what needs to be done next. I would like you to understand well by this moment, what will be discussed when they will explain everything in detail to you, what was found during the examination, what diagnosis was made, what needs to be done and when to choose the best way of treatment.

Here and now the main questions are being decided, and you must exactly imagine what you want to know before you make a decision on which a lot depends.

There are several options for conversation.

You will be offered operation, as the only way out, and doctors believe that it needs to be done urgently.
You are offered an operation, but they say that it can be postponed for a while.
You are denied an operation for a variety of reasons.

You need to understand what is being said and prepare for the conversation. Try to be calm and confident in yourself and in the doctors who want to help you. You must be together, on the same side, in the fight for the future of the child. Discuss everything, but your questions should be literate. Believe me, a lot depends on this too.

What do you need to have an idea about in order to ask the right question? What are the operations? What should the child do? How will it all be? Who will do it? Let's talk about it calmly.

Today, all interventions, or operations, for congenital heart defects can be divided into three categories: "closed" operations, "open" and "X-ray surgery".

✔ Closed Operations These are surgical interventions in which the heart itself is not affected. They are performed outside of it, and therefore do not require the use of any special equipment other than conventional surgical instruments. The cavities of the heart are not “opened” with them, which is why they are called “closed”, and they are widely performed as the first stage of surgical intervention.

✔ Open Operations- These are surgical interventions in which it is necessary to open the cavities of the heart in order to eliminate the existing defect. For this, a special apparatus is used - a heart-lung machine (AIC), or "heart-lungs". For the period of the operation, both the heart and the lungs are switched off from the circulation, and the surgeon gets the opportunity to perform any operation on the so-called "dry", stopped heart.

All the patient's venous blood is sent to the apparatus, where, passing through an oxygenator (artificial lung), it is saturated with oxygen and gives off carbon dioxide, turning into arterial. Then the arterial blood is pumped into the patient's aorta by a pump, i.e. into the systemic circulation. Modern technologies allow all the internal parts of the device (including the oxygenator), with which the patient's blood comes into contact, to be made "disposable", i.e. use them only once and only for one patient. This dramatically reduces the number of possible complications.

Today, thanks to AIC, it is possible without much risk to turn off the heart and lungs from work for several hours (and the surgeon has the opportunity to operate on the most complex defects).

✔ X-ray surgery appeared relatively recently, but, thanks to the incredible progress of modern technologies, they have already taken their rightful place in the arsenal of cardiac surgery. Increasingly, physicians today are using thin catheters ending in balloons, patches, or expandable tubes (folded like a collapsible umbrella). With the help of a catheter, these devices are carried into the cavity of the heart, or into the lumen of the vessel, and then, by expanding the balloon, they break the narrowed valve with pressure, increase or create a defect in the septum, or, on the contrary, by opening the patch umbrella, this defect is closed. The tubes are inserted into the lumen of the desired vessel and create a wider lumen. In adults, they even try to pass an artificial aortic valve through the catheter in this way, but so far these are only attempts. Doctors monitor the course of an X-ray surgical operation on the monitor screen and clearly control all manipulations with the probe, and therefore the advantage of such operations is not only less trauma, but also high safety and efficiency. X-ray surgery has not yet supplanted traditional surgical methods, but it is gaining more and more space both as an independent method and as an “auxiliary”, i.e. which can be applied not instead of, but together with the usual operation, sometimes simplifying and supplementing it in many ways.

Depending on the type of defect and the condition of the child, surgical operations can be emergency, urgent and elective, i.e. planned.

emergency heart surgery are the ones that need to be done immediately after the diagnosis is established, because any delay threatens the life of the child. With congenital malformations, such situations are not uncommon, especially when it comes to newborns. Here the question of life is often decided by hours and minutes.

Emergency operations- those for whom there is no such insane urgency. The operation does not need to be done right now, but you can calmly wait a few days, prepare both you and the child, but it must be done urgently, because then it may be too late.

Planned, or elective, operation- this is an intervention made at the time chosen by you and the surgeons, when the child's condition does not inspire fear, but the operation, nevertheless, should not be postponed.

No cardiac surgeon will ever suggest surgery if it can be avoided. So, anyway, it should be.

Depending on the approach to surgical treatment, radical and palliative operations are distinguished.

✔ Radical heart surgery- This is a correction that completely eliminates the defect. It can be done with an open ductus arteriosus, septal defects, complete transposition of the main vessels, abnormal pulmonary venous drainage, atrioventricular communication, Fallot's tetrad and some other defects, in which the heart is fully formed, and the surgeon has the opportunity to completely separate the circulatory circles, while maintaining normal anatomical relationships. Those. the atria will connect to their ventricles through correctly located valves, and the corresponding great vessels will depart from the ventricles.

✔ Palliative heart surgery- auxiliary, "facilitating", aimed at normalizing or improving blood circulation and preparing the vascular bed for radical correction. Palliative operations do not eliminate the disease itself, but significantly improve the child's condition. With some very complex defects, which until recently were generally inoperable, the child will have one, and sometimes two palliative operations, before the final radical stage becomes possible.

During a palliative operation, another "defect" is surgically created, which the child does not initially have, but due to which the circulatory pathways disturbed by the defect in the large and small circles are changed. These include surgical expansion of the atrial septal defect, all variants of intervascular anastomoses - i.e. additional shunts, messages between circles. The Fontan operation is the most “radical” of all such methods, after which a person lives without a right ventricle at all. With some of the most complex heart defects, it is impossible to correct the anatomically, and surgical treatment aimed at correcting blood flow can be called the “final” palliative correction, but by no means a radical operation.

In other words, with heart defects, when the intracardiac anatomy - the structure of the ventricles, the condition of the atrioventricular valves, the location of the aorta and the pulmonary trunk - are so changed that they do not allow for a real radical correction, today's surgery follows the path of eliminating poorly compatible with life of circulatory disorders, and then - long-term palliation. The first stage of this path is saving lives and preparing for further treatment, and protection from future complications, the second is the final stage of treatment. All together - this is a long way to the final operation, and on it one, two, and sometimes three steps must be overcome, but, ultimately, to make the child healthy enough for him to develop, learn, lead a normal life, which this long-term palliation will provide him. Check it out, not so long ago - 20-25 years ago it was simply impossible, and children born with the defects of this group were doomed to death.

Such a “final palliation” is the only way out in many cases; although it does not correct the defect itself, it provides the child with an almost normal life by improving the mixing of arterial and venous blood flows, the complete separation of circles, and the elimination of obstructions to blood flow.

Obviously, the very concept of radical and palliative treatment for some complex congenital heart defects is largely arbitrary, and the boundaries are erased.

Tuesday is surgery day. The team is preparing for a long morning work. During the operation, the chest is opened and the heart is prepared for vessel transplantation.

Disease history

Mr. Thomas, a 59-year-old tanker driver, is married with two adult children. He had shingles on the right side of his neck, followed by an uncomfortable constriction in his throat, accompanied by sweating and nausea. He first felt these symptoms while walking up the steps of his truck. They continued, and Thomas decided to seek the advice of a therapist.

Thomas's high blood pressure, obesity, and long history of smoking were reason enough for an ECG. Her results showed the presence of coronary heart disease. Thomas was referred to a cardiac expert (a cardiac internist, not a surgeon). Despite the applied medical treatment, the pain continued.

Tests confirmed the presence of the disease, in particular an angiogram (a test using a dye injected into an artery to detect narrowing) revealed a narrowing in the left main coronary artery with damage to the left and right vessels. Since medical treatment was unsuccessful and angioplasty (stretching a narrowed vessel using a catheter) was not an option, Mr. Thomas was referred for surgery.

Monday

Mr. Thomas is hospitalized. His anamnesis, data of examinations and tests were analyzed. Two units of blood for transfusion are tested for compatibility. The patient is explained the essence of the operation and warned about the risk associated with it. Obtain written consent for CABG.

Tuesday

Early in the morning, Mr. Thomas is being prepared for the operation.

7:05 Premedication and anesthesia

8:15 a.m. Mr. Thomas was sedated 70 minutes ago and a ventilation tube has already been placed in his airway. After the application of anesthesia and paralyzing agents, his breathing is supported by a ventilator. Prior to transferring Mr. Thomas to the operating room, the anesthesiologist establishes monitoring of venous and arterial blood flow.

8:16 OR Mr. Thomas is set up. On the left - a table with instruments, on the right - a ready-to-use heart-lung apparatus.

8:25 Patient in the operating room. The skin of his chest and legs are treated with an antiseptic solution to reduce the risk of infection.

8:40 Opening of the chest

The skin has already been processed, the patient is dressed in sterile clothes. One of the surgeons makes an incision in the leg to extract the vein, and the second cuts the skin on the chest. After a preliminary incision with an ordinary scalpel, he uses an electric one, which cuts the vessels, stopping the bleeding.

8:48 The surgeon cuts the sternum bone with an electric saw with a pneumatic drive.

8:55 Artery and vein removal

View of the internal thoracic (mammary) artery in the mirror in the center of the surgical lamp. This artery is very elastic. The top end of it will remain in place, it will be cut off at the bottom and then connected to the coronary artery.

An angled retractor is placed along the left edge of the sternum to lift it and expose the mammary artery that runs along the inside of the chest.

At the same time, one of the main veins on the leg - the great saphenous vein - is prepared for transplantation. It is almost completely removed from the left thigh.

9:05 Connecting to the heart-lung machine

The heart-lung machine is not yet connected to the patient. One of the five rotating pumps circulates the blood, while the rest are used as side pumps to transport separated blood to prevent blood loss during surgery. The patient needs to enter heparin - a means to thin the blood and prevent the formation of clots during its passage through plastic tubes.

Tubes to the heart-lung apparatus. On the left, with bright red blood, is the arterial return line, which carries blood back into the patient's aorta. On the right - two tubes that drain blood from the inferior and superior vena cava under the influence of gravity. The incision in the sternum is fixed with a spacer.

Part of the heart-lung apparatus is a membrane oxygenating device that maintains blood circulation in the patient's body. At the moment, the device is filled with blood, carbon dioxide is removed from it. The blood is re-oxygenated and returned to the patient's body.

An arterial return tube is inserted into the aorta (the main artery of the body) and two venous drains are inserted into the vena cava (the main vein of the body).

9:25 Cardiac arrest

On the main artery - the aorta - a clamp is placed to isolate the heart from artificial blood circulation. Chilled fluid is injected into the isolated aorta to stop the heart. The surgeon puts on special glasses for microsurgery with loupes that give a magnification of 2.5 times. The blood vessels he will transplant are 2-3 mm in diameter, and the sutures are the diameter of a human hair.

A thorough examination of the heart is carried out to confirm the data obtained using the angiogram. It is specified which coronary arteries need to be bypassed. It was decided to make two shunts.

After stopping the blood flow in the left anterior descending artery, a 1 cm long incision is made at the bypass site using a surgical loop.

10:00 First bypass

Close-up of the heart. The left internal mammary (mammary) artery - in the upper left corner - is sutured to the left anterior descending artery so that blood flow to the heart is restored. Arteries are hidden by epicardial fat.

The end of the left internal mammary artery is sutured laterally to the left anterior descending artery. This forms the first bypass shunt.

The position of the first performed shunt. The end of the lower part of the left internal mammary artery - a blood vessel with a diameter of 3 mm - is completely sutured to the left anterior descending artery.

10:22 Second bypass

The second bypass shunt is sutured with the upper end to the aorta, and with the lower end to the right posterior descending artery. The transverse clamp is removed, blood flow through the heart is restored.

The upper end of the venous shunt is connected to the aorta. Part of the aorta is isolated with an arcuate clamp and a hole is made into which a vein is sutured.

End of both bypass processes. The second shunt, shown on the left side of the diagram, is formed from the saphenous vein of the leg.

11:18 Chest closure

Circulation is restored, the heart contracts after an electric shock with the transition from ventricular fibrillation to sinus mode. Two drains are installed in the anterior and posterior parts of the heart. The blood thinning effect of heparin was eliminated by the drug protamine. The surgeon sews the separated halves of the sternum together. The skin will be closed with an internal absorbable suture.

The nurse applies tape to the suture and to the drainage tubes leading from the patient's chest. Soon the patient will be placed in the intensive care unit, where he will be observed.

How are operations performed?

An operation is an intervention in the human body with a violation of its integrity. Each disease requires an individual approach, which naturally affects the way the operation is performed.

How heart surgery is done: preparation for surgery

Heart surgery (cardiac surgery) is one of the most difficult to perform, dangerous and responsible type of surgical intervention.

Planned operations are usually carried out in the morning. Therefore, the patient is not allowed to eat or drink in the evening (for 8-10 hours), and immediately before the operation, a cleansing enema is made. This is necessary in order for the anesthesia to work as it should.

The place where operations are performed must be sterile. In medical institutions, special rooms are used for these purposes - operating rooms, which are regularly sterilized by quartz treatment and special antiseptics. In addition, all medical personnel who take part in the operation wash themselves before the procedure (you even have to rinse your mouth with an antiseptic solution), and also change into special sterile clothes, put on sterile gloves on your hands.

The patient is also put on shoe covers, a cap on his head, and the operation field is treated with an antiseptic. If necessary, before the operation, the patient's hair is shaved if the surgical field is covered with it. All these manipulations are necessary to avoid infection of the surgical wound with bacteria or other dangerous active microorganisms.

Narcosis or anesthesia

Anesthesia is a general anesthesia of the body with its immersion in drug-induced sleep. During surgical interventions on the heart, general anesthesia is used, and in some cases, during endovideosurgical operations, spinal anesthesia is used, in which a puncture is made into the spinal cord at the level of the lower back. Substances that cause pain relief can be administered in various ways - intravenously, through the respiratory tract (inhalation anesthesia), intramuscularly or in combination.

Course of open heart surgery

After the person goes into medical sleep and ceases to feel pain, the operation itself begins. The surgeon uses a scalpel to open the skin and soft tissues on the chest. Cardiac surgery may also require an “opening” of the chest. To do this, with the help of special surgical instruments, the ribs are sawn. Thus, doctors “get” to the operated organ and put special dilators on the wound, which provide better access to the heart. Junior medical staff, using suction, removes blood from the surgical field, and also cauterizes cut capillaries and blood vessels so that they do not bleed.

If necessary, the patient is connected to an artificial heart machine, which will temporarily pump blood through the body, while the operated organ is artificially suspended. Depending on what kind of heart surgery is performed (what kind of damage is eliminated), appropriate manipulations are carried out: this can be the replacement of blocked coronary arteries, the replacement of heart valves for defects, vein bypass surgery or the replacement of an entire organ.

Extreme care is required from the surgeon and all staff, as the life of the patient depends on it. It should also be added that during the operation, blood pressure and some other indicators are constantly monitored, which indicate the patient's condition.

Endovideosurgery: stenosis and angioplasty

Today, more and more often, heart surgery is performed not by an open method - with a chest incision, but with access through the femoral artery on the leg, under the control of an X-ray machine and a microscopic video camera. After preparing for operation, which is similar for all types of surgical interventions, and putting the patient into a medical sleep, access to the femoral artery is opened through an incision in the leg. A catheter and a probe with a video camera at the end are inserted into it, thanks to which access to the heart is provided.

In this way, angioplasty with stenosis of blood vessels is carried out in cardiac surgery, which is necessary for blockage of the coronary vessels that feed the heart itself with blood. Special stands are installed in the narrowed vessels - cylindrical implants that do not allow the arteries to clog anymore, which prevents the possibility of developing coronary disease.

After the main part of the operation is over and the heart is on its own again functions, stitching of damaged nerves, vessels and tissues is performed. The wound is again treated with an antiseptic, the surgical field is closed, soft tissues and skin are sutured with special threads. A medical bandage is applied to the external wound. After the end of all these procedures, the patient is taken out of anesthesia.

Other types of operations

In addition to the abdominal operations described above, there are also operations performed in a less traumatic way:

Laparoscopy - is performed using a laparoscope, which is inserted through 1-2 cm incisions in the skin. Most often used in gynecology, gastrectomy and other operations in the abdominal cavity. You can read more about this
Laser surgery - is carried out using a special laser beam. Usually, operations are performed in this way on the eyes, when removing skin formations, etc. You can read more about the method
