CoronaryArtery Bypass graft
(CABG) surgery involves
opening the chest and temporarily directing the blood through
a heart-lung
machine, which takes care of circulation while the heart is
cooled, stopped, and repaired. Blockages in the coronary
arteries are bypassed by
harvesting a blood vessel from elsewhere in the body and sewing it onto the coronary
artery so
as to reroute the blood flow around the blockage. Once the repair is
complete, the heart is warmed and restarted, and the chest is closed.

CoronaryAngioplasty
Please, don't
misunderstand, an emergency angioplasty, when you are on the table
having a heart attack can do three important things:
- Restore blood flow immediately
- Prevent further heart damage
- Save your lifeHowever, in many cases the procedure does not have lasting benefits. What happens in many cases is that the artery undergoes restenosis. It becomes a clogged artery again, in the same spot!
Bypass
Surgery
Bypass
surgery, CABG,
has similar poor results yet bypass
surgery is
more successful in regards to restenosis than is stenting via
angioplasty.
A
surgical team may strip a vein from your leg and graft it to an
artery in your heart and restore blood flow at that site but since
atherosclerosis does not affect just one section of one artery, it
affects your whole arterial system, bypass
surgery often
has to be performed several times or until you have no suitable leg
or arm veins to use in the procedure. And of course those procedures
carry risks, in fact 5 percent of patients die during or within 2
weeks of the procedures and another small percentage have been known
to leave this life 90 days after bypass surgery.
Coronary artery bypass surgery is the flow of blood around arteries which are clogged. This improves the flow of blood and oxygen to the heart. Coronary arteries, which are the arteries through which blood flows to the heart, can sometimes become clogged by the buildup of cholesterol or fat. This clogging slows or stops the flow of blood to the heart, which in turn can lead to pain in the chest, or even a heart attack. The object of heart bypass surgery is to increase the flow of blood to the heart to restore optimal heart functioning.
The surgeon takes a piece of blood vessel from the chest or leg of the patient and grafts it onto the aorta, the artery which leaves the heart, and then he grafts the other end to the coronary artery beneath the block, thus creating a detour around the arterial blockage. The number of bypasses - single, double, triple, quadruple - refer to how many coronary arteries are bypassed in the operation, which depends upon the number of blocked coronary arteries. A triple bypass Illinois means that three coronary arteries are bypassed. In some bypass operations a heart lung machine is employed to maintain the flow of blood and oxygen to the heart during the procedure.
When the surgery is over the patient is placed in the intensive care unit so that the heart rate and the blood pressure can be monitored continuously for a day or so. Medication which regulates blood pressure and circulation are given intravenously, and a breathing tube may be used until the patient is able to breathe alone.
