So as to achieve the purpose of relieving angina symptoms, improving cardiac function, improving the quality of life of patients and prolonging life. Heart bypass is very severe and cannot be taken lightly.
Heart bypass surgery refers to
Cardiac bypass surgery, commonly known as coronary artery bypass surgery, is internationally recognized as the most effective method to treat coronary heart disease. It refers to coronary artery bypass grafting or heart bypass surgery when one or more coronary arteries are seriously blocked or blood supply is very insufficient. A comprehensive examination should be conducted before the operation to determine the exact location of the obstruction.
During the operation, it is necessary to cut off the blood supply from the heart to the body, so it is necessary to use a heart-lung machine for extracorporeal circulation of blood to protect the normal movement of important organs such as the brain.
Detailed description of the process
Coronary artery stenosis of coronary heart disease is mostly segmental distribution. Mainly located in the proximal and middle segment of coronary artery, the distal segment is more normal. Coronary artery bypass grafting is to establish a channel between the proximal end and the distal end of coronary artery stenosis, so that blood can bypass the middle of the stenosis and reach the distal end, just like a bridge to make the road cross mountains and rivers.
But the material used is not reinforced cement, but the patient's own great saphenous vein, internal mammary artery, right gastroepiploic artery and radial artery. Take the great saphenous vein from the leg or thigh, one end of which is anastomosed with the distal end of coronary artery stenosis, and the other end is anastomosed with ascending aorta. At the same time, several lateral holes can be opened in a vein to anastomose with several coronary arteries, which is called sequential bypass or snake bridge.
Coronary artery bypass surgery is a kind of open heart surgery. The operation will be carried out in two parts at the same time, one is the operation of the heart itself, and the other is the operation of blood vessel sampling by leg bypass. Bypass blood vessels will be bridged above the coronary artery occlusion area to restore blood supply to the myocardium.
