Coronary Artery Bypass Graft

What is Coronary Artery Bypass Graft (CABG)?

Coronary Artery Bypass Graft (CABG) surgery is to graft normal blood vessels to  the heart by  connecting the main artery and the normal arteries,  bypassing the coronary artery stenosis.  The situation is just like a bridge erected , so that blood can once again go through to supply oxygen to relieve the myocardial condition.
CABG surgery patients will go under general anesthesia. The doctor will first cut the patient's  chest median sternotomy incision. The right atrial venous drainage tube is inserted, blood will be drained into the cardiopulmonary bypass machine, after adding oxygen, then it will flow back into the patient's body. In addition, to ensure that the surgery is completed under the state without blood, the doctor will clamp the aorta to suspend blood flow, the heart will be will during the period. 2-4 blood vessels will usually be grafted during a bypass surgery, it will take about 3-4 hours.
Leg saphenous vein is commonly used in CABG; because it is long, it can be used for multiple bypass. Many patients are worried that removal of a blood vessel from the leg will affect the ability to walk. In fact, this does not affect the leg's function. Data show that 60% of patients' bypass remain smooth 10 years after the surgery; 50% of patients' bypass had become moderately narrow.  This is because as time goes by the proliferation of cells in the vascular wall adhesion that results in vein narrowing. In recent years, invasive surgical techniques can be applied to this surgery.
More and more people use  mammary artery in the breast in CABG. The 10-year rate has increased from 60% to 90%. However, due to the limited length of mammary artery, it is only suitable for CABG that goes through the front the heart. In addition, in recent years an increasing number of radial forearm have been used in bypass surgery in younger patients.
