Coronary Artery Disease in sometimes may not respond to other treatments. A Coronary Artery Bypass Graft Surgery is used in such cases. The narrowing of the coronary blood vessels due to plaque builup is called Coronary Artery Disease. The narrowed coronary arteries can be treated with various other treatment options too. When the condition of the patient is very severe that the other surgeries cannot openup the narrowed arteries. CABG is used in such conditions.
CABG is considered to be one of the most common type of open-heart surgery. The main aim of the procedure is to open the blocked arteries. During the surgery, a blood vessel from another part of the body is attached to the coronary artery near to the blockage or narrowed area. This process is called grafting. According to the severity of the condition, the number of grafts required may vary. It may also depend upon how many blockages are there or how many veins have got narrowed. The entire procedure is carried out under general anesthesia. The surgery may require around 4 hours to complete.
The conventional bypass surgery is done by putting the patient on heart lung machine, bringing the heart to a complete stand still and then restarting the heart after the grafting process is complete.
Skilled surgeons can now perform grafting on beating hearts using special clamps and thus avoiding the need of heart lung machine
The patient may need to stay in the hospital for a few days after the surgery. Recovery time may vary according to different cases. The patient will be able to return to normal physical activities after six weeks or more. Full recovery will be possible within 12 weeks from the day of surgery. CABG carries risks and complications of a common surgery. There can be minor wound infection, irregular heartbeat etc. In very rare cases, the patient may get a Heart Attack or stroke. After the surgery, the patient will get relief from symptoms of coronary artery disease. But, it cannot completely cure CAD (coronary artery disease). The patient may need to make certain lifestyle changes also to benefit more from the surgery.
