Coronary Artery Bypass Graft Surgery
Coronary artery bypass grafting (CABG) is a system to improve poor blood stream to the heart. It very well might be required when the veins providing blood to heart tissue, called coronary arteries, are limited or hindered. This medical procedure may bring down the danger of serious complications for individuals who have obstructive coronary artery disease, a sort of ischemic coronary disease (CAD). CABG may likewise be utilized in a crisis, for example, an extreme cardiac failure.
CABG utilizes blood vessels from another part of the body and interfaces them to blood vessel above and beneath the narrowed artery, bypassing the blocked or narrowed artery. One more blood vessels might be utilized, depending upon the seriousness and number of blockages
One approach to treat the blocked or narrowed arteries is to bypass the blocked portion of the coronary artery with a piece of a healthy blood vessel from elsewhere in your body. Blood vessels, or grafts, used for the bypass procedure may be pieces of a vein from your leg or an artery in your chest. An artery from your wrist may likewise be utilized. Your doctor joins one end over the blockage and the opposite end underneath the blockage. Blood bypasses the blockage by going through the new graft to reach the heart muscle. This is called coronary artery bypass surgery.
Traditionally, to bypass the blocked coronary artery, your doctor makes a large incision in the chest and temporarily stops the heart. To open the chest, your doctor cuts the breastbone (sternum) in half lengthwise and spreads it apart. Once the heart is exposed, your doctor inserts tubes into the heart so that the blood can be pumped through the body by a heart-lung bypass machine. The bypass machine is necessary to pump blood while the heart is stopped.
While the traditional "open heart" procedure is still commonly done and often preferred in many situations, less invasive techniques have been developed to bypass blocked coronary arteries. "Off-pump" procedures, in which the heart does not have to be stopped, were developed in the 1990's. Other minimally invasive procedures, such as keyhole surgery (done through very small incisions) and robotic procedures (done with the aid of a moving mechanical device), may be used.
