Coronary Artery Bypass Grafting (CABG), likewise known as bypass surgery, is the most performed surgery for blocked vessels. When blood stream in the arteries is blocked, and the blood supply to heart muscle reduces, Coronary Artery Bypass Grafting is performed. If Coronary Artery Bypass Grafting is not done then these blockages results in heart attack. CABG is a surgery that is planned to done to bypass the blood around these blockages. Another artery or vein from legs are used to “bypass” the blockage.
The operation begins, after general anesthesia is induced and the whole procedure takes approximately 3-4 hours to complete. Patients are completely asleep during the entire course of the operation. Medical team removes saphena vein from patient’s leg. The length of the incision in leg dependents upon the length of the saphena vein required to complete the number of “bypasses” planned. You will be astonished to know that there are many veins in a human body those are not of any use. Once removed from the leg, this vein will be cut short into smaller segments, each of which will be used for individual bypasses.
