What is coronary bypass? What diseases does it show?
Aortic coronary bypass, or simply coronary bypass, is an operation aimed at restoring blood flow to large cardiac arteries. Aortic coronary bypass, the arterial data is narrowed due to ischemic heart disease, atherosclerosis. Surgeons put shunts to increase the flow of blood to the heart, creating a bypass pathway on the vessels. To whom can such operation help?
Indications for coronary bypass surgery
The main indications for the operation are as follows:
In the patient, the left carotid artery is 50% impassable.
The patient has narrowed all cardiac vessels by more than 70%.
Patients were diagnosed with stenosis of the arteries of the heart in combination with stenosis of the proximal anterior cerebrovascular artery.
Coronary bypass is indicated for patients with angina pectoris, signs of myocardial ischemia, those for whom medication has been shown to be ineffective. There are also patients who need an extra by-line shunting before or during another heart surgery. For example, it is recommended to carry out a bypass before the operation on the valves, with ischemia of the myocardium.
What are the benefits of coronary bypass?
Thanks to this operation it is possible:
To restore blood flow to the cardiac arteries, which has deteriorated due to their narrowing.
Return the patient to a virtually normal life after surgery, significantly reducing the risk of myocardial infarction and other concomitant heart disease.
Stop the attacks of angina, which significantly affect the deterioration of human activity.
To provide a long curative effect, increase the life expectancy of normal quality.
Possible complications after surgery
Like any surgery, cardiovascular bypass has certain risks. The main ones are as follows:
Development of bleeding.
Thrombosis of veins.
Development of atrial fibrillation.
Stroke as a result of disturbance of blood circulation in the vessels of the brain.
Infection as a result of surgery.
All these complications are unlikely, but they are possible. Any surgical intervention is a risk, it is necessary to be ready for this. Complications are more likely if the patient has severe angina pectoris, atherosclerosis, a generalized state. Therefore, the earlier the operation was performed, the more favorable outcome. In women, complications occur more frequently than in men, due to the smaller diameter of coronary vessels. Also higher risks in elderly patients, those with diabetes mellitus, chronic pulmonary disease, renal failure, and poor blood coagulation.
Successfully performed coronary bypass allows you to correct the problem with the health of the patient. However, it should be taken into account that it is impossible surgically to cure the disease that provoked the need for a bypass, – atherosclerosis. Therefore, it is very important after the operation to adhere to the principles of proper nutrition, control blood pressure, do not smoke, do not gain excess weight, control blood sugar levels, and walk more in the fresh air. Also, the patient should avoid stressful situations.
Coronary bypass is a rather effective operation that can significantly improve the quality of a person’s life. If the cardiologist recommends it, most likely he has it for this purpose, and he needs to listen. However, this operation should be properly prepared, as well as not forget about the importance of responsible attitude in the postoperative period.
