Bypass surgery also known as coronary artery bypass graft CABG is a surgical procedure to improve blood flow to the heart. This procedure is done on patients with severe coronary heart disease in which waxy substance called plaque builds up in the arteries & makes it hard & narrow which over the time affects the supply of oxygen rich blood to your heart. Lifestyle modifications, medicines, angioplasty are options to open the narrowed arteries, if these treatments don’t help, coronary artery bypass grafting is the only option.
In Bypass surgery, a surgeon takes a piece of vein from leg or wrist to create a new path for blood and oxygen to flow to the heart without any interruption. New vein attached to the coronary artery, just above or below the blockage or narrowed area. This allows blood to bypass the blockage. Sometimes depending on the patient’s condition, surgeon can bypass multiple arteries during one procedure.
The results of the surgery are excellent, patient remain symptom-free for many years and can live a healthy life. Lifestyle modification and regular medicines may help stop arteries from becoming clogged again.
Expected recovery period is about 6 to 10 weeks. Patient can resume work and begin exercising after doctor’s approval; generally it takes after 4 to 6 weeks.
A bypass surgery is used for treatment of the blocked arteries. A bypass is created around the section of a blocked artery using a graft. A graft can be either natural or artificial; a natural graft consists of a portion of the vein, whereas an artificial graft can be a man made synthetic tube that works as a vein.
Open-heart surgery is a procedure where chest is cut, open and surgery is performed on the muscles, valves, and arteries of the heart. During this surgery, heart beating is temporarily stopped and the demand of oxygen is fulfilled by a heart-lung machine.
CABG lowers the risk of heart attacks, stroke and paralysis. Patient can remain symptom free for as long as 15-20 years. It also improves the pumping action of your heart because of the better blood flow.
