Coronary Bypass Surgery Success Rate


Coronary Bypass Surgery Success Rate  

A Coronary Bypass Surgery or a Coronary Artery Bypass Surgery is also called CABG or “cabbage”. It is the most common type of heart surgery performed today.  Research says that in the United States, each year not less than 260,000 people have had successful bypass surgeries performed on them.  How this name derives its origin is because it is done to “bypass” the flow of blood around the clogged arteries so that the heart is not affected.

Artery blockage can happen due to a number of reasons. The most common is because of fatty plaques which tend to deposit in the artery as the person grows older. These fatty plaques contain substances such as cholesterol deposits. In most cases, this leads to chest pain and the impending danger of a heart attack. Hence, the surgery is done to channel the blood flow in such a way so as to not affect the heart.

During a bypass surgery, surgeons divide the sternum or the breast-bone and stop the heart. Blood flow takes place through a heart-lung machine generally called pump oxygenator. During the surgery, a bypass graft is performed by using a vein or artery from other parts of the body such as the thigh, leg or the fore-arm. These are attached at one end of the aorta and to the coronary artery beyond the blockage at the other end. Studies show that a graft constructed from a Left Internal Mammary Artery has a 90-95 percent chance of running without incidence for at least ten years. Nevertheless, grafts that have worked well for a year do well for the next 3-4 years without causing problems.
