Coronary artery bypass graft surgery (CABG surgery, "cabbage" surgery) is a method of unblocking clogged arteries. During the surgery, a blood vessel is removed and used as a bypass around a blocked blood vessel. The grafted vessel can come from a number of places in the body. More than one of these grafts may be done during the same surgery. One option for this type of surgery is minimally invasive heart bypass surgery, which leaves a smaller scar and requires a shorter recovery time.
