What condition makes cardiac stent
summary
Heart bypass surgery, as the name suggests, is to use its own blood vessels (such as internal thoracic artery, lower extremity, great saphenous vein, etc.) or vascular substitutes to connect the distal end of the stenotic coronary artery with the aorta, so that the blood can bypass the stenotic part to reach the ischemic site, improve the blood supply of the myocardium, so as to relieve the symptoms of angina pectoris, improve heart function, and improve the quality of life of patients Quantity and the purpose of prolonging life. This kind of operation is called coronary artery bypass grafting. It is to build a smooth path between the main artery, the root of the artery and the ischemic myocardium, which is full of arterial blood. Therefore, some people vividly regard it as a bridge built on the heart, commonly known as bypass surgery.
What condition makes cardiac stent
First, because of the large injury of artery bypass graft, high technical requirements, the operation is more difficult, but the long-term effect is larger, the saphenous vein is good, and it is suitable for young patients. Under normal circumstances, the elderly over 80 years old can use saphenous vein bypass alone, under 50 years old, can consider using artery bypass, other age can use an internal mammary artery, plus saphenous vein.
Second: left trunk lesions: according to the guidelines at home and abroad, surgery is the first choice for left main trunk lesions, because once the left main trunk is blocked or restenosis, it may be fatal. In order to reduce the risk, it is best to choose bypass. Three vessel disease: there are many diseased vessels. If we choose interventional therapy, we need to put a lot of stents, which will greatly increase the risk of restenosis and thrombosis, and the economic burden of patients is also heavy.
Third: with cardiac insufficiency, this kind of patients need complete revascularization to promote the recovery of ischemic myocardium, and intervention is difficult to achieve. Patients with diabetes mellitus: the restenosis rate of common stents is higher in patients with diabetes mellitus, while drug-eluting stents have been available for a short time. There is no clear evidence that interventional therapy is better than bypass.
matters needing attention
Because the stent requires patients to take antiplatelet drugs, patients allergic to this drug should also consider bypass surgery. However, if the patient has respiratory diseases, it may be dangerous to receive general anesthesia. It is not suitable to receive conventional cardiopulmonary bypass, but should choose interventional therapy.
