What is Coronary Artery Bypass Surgery ?
Coronary Artery Bypass Graft Surgery (CABG) is a surgical method performed to improve the flow of blood & oxygen to the heart muscle. The narrowing of the coronary arteries hinders the blood flow through the blood vessels of the heart and can cause a heart attack. The major reason behind the blockage of arteries is the accumulation of fatty substances and cholesterol over a period of time. The surgery helps in re-routing blood to the heart muscles, relieving chest pain and improves function of the heart muscles.
Procedure for Coronary Bypass Surgery
During a Coronary Artery Bypass Graft Surgery (CABG), the blood flow is re-routed around the clogged artery by detaching a long segment of an artery from the chest wall, arms or leg veins. Thereafter, the new artery is grafted to the clogged area of the coronary artery. Through the newly attached channel, blood gets unhindered route to flow to the heart muscles. This procedure is known as Coronary Artery Bypass Surgery. Depending upon the number of blocked coronary arteries, a patient may undergo more than one bypass graft.
