This is really a type of heart surgery. It's from time to time known as CABG ("cabbage"). The surgery reroutes, or "bypasses," blood around clogged arteries to increase blood flow and oxygen to the heart.
The arteries that bring blood to the heart muscle (coronary arteries) can become clogged by plaque (a buildup of fat, cholesterol plus other substances). This can then slow or stop blood flow by way of the heart's blood vessels, leading to chest pain or a heart attack. Growing blood flow to the heart muscle can relieve chest pain and also lessen the risk of heart attack.
Surgeons take a segment of a healthy blood vessel from an additional part of the body, and then make a detour around the blocked part of the coronary artery. An artery might be detached from the chest wall as well as the open end attached to the coronary artery below the blocked location. Or a piece of a long vein within your leg could be taken. 1 end is sewn onto the large artery leaving your heart - the aorta. The other end of the vein is attached or "grafted" to the coronary artery below the blocked area.
Either way, blood can then utilize use this new path to flow freely to the heart muscle.
A patient may possibly undergo 1, two, 3 or more bypass grafts, depending on how numerous coronary arteries are blocked.
Cardiopulmonary bypass with a pump oxygenator (heart-lung machine) is employed for many coronary bypass graft operations. This means that besides the surgeon, a team produced up of a cardiac anesthesiologist and surgical nurse, a competent perfusionist (blood flow specialist) are required.
What occurs soon after bypass surgery?
Following surgery, the patient is moved to a hospital bed within the cardiac surgical intensive care unit. Heart rate and blood pressure monitoring devices continuously monitor the patient for 12 to 24 hours.
