Bypass surgery, as the name suggests, takes the patient's own blood vessels (such as the internal thoracic artery, the saphenous vein in the lower limbs, etc.) or vascular substitutes, connects the distal end of the narrowed coronary artery with the aorta, and lets the blood flow through the narrowed portion to reach the ischemic part to improve the myocardium's blood supply, thus relieving the symptoms of angina pectoris, improving the function of the heart, and enhancing the patient's quality of life and prolonging his or her life. The goal. The procedure, known as coronary artery bypass grafting, creates a smooth path between the root of the aorta, which is full of arterial blood, and the ischemic heart muscle, and is therefore imaginatively referred to as "bridging the gap" between the heart and the artery, commonly known as "bypass surgery".
Cardiac bypass surgery, which involves bypassing blocked arteries to improve the supply of blood and oxygen to the heart, has the potential to affect memory and mental functioning, so much so that about one-third of patients still show detectable mental impairment five years after the surgery.
To minimize and reduce the risk, it is important to keep the grafted segment of the heart bypass open and reduce the need for repeat heart bypass surgery.
In patients who have just had heart bypass surgery, depression can cause a threefold risk of heart disease within the first year of surgery.
1, infants and young children with congenital vascular malformations and large vessel transposition correction; 2, children and adults with congenital cardiac malformations; 3, valve replacement for rheumatoid artery disease; 4, coronary artery bypass grafting, the risk of each operation is different, the domestic reports of the entire cardiac surgery mortality rate of about 5% - 8%, coronary artery bypass grafting rate of less than 1 percent. The mortality rate for coronary artery bypass grafting is less than 1%.
