What is Coronary Bypass Surgery?
Coronary Bypass Surgery is an operation in which a bypass or bridging is performed with a vessel taken from another part of the body in order to minimize the damage as a result of the occlusion or narrowing of the coronary vessel that feeds the heart.
In this operation, the vein is not changed. The blood flow is provided by suturing the new vessel to the next area from the occluded place. Thus, the clogged area is bypassed, and the name of the operation comes from this. Thus, it is aimed to provide the necessary blood flow beyond the vein and to re-deliver the blood.
In bypass surgeries, the left mammary artery, leg vein or arm artery are generally used. Since these vessels do not cause any dysfunction in the regions and organs where they are located, they can be easily taken and used. However, the most ideal vein in bypass surgeries is the chest vein.
Coronary Bypass Surgery has been performed as open heart surgery for years by cutting the breastbone (board of faith) and stopping the heart. Today, there have been changes with the developing technology and the experience we have gained as a result of these surgeries that we have applied to thousands of patients. On the one hand, the harmful effects of the heart-lung machine that we used during the operation emerged and operations started to be performed while the heart was working (Beating Heart). In this case, there is no need to use a heart-lung machine, bypass surgery is performed while the heart continues to function normally. For this, the vessel is fixed with a special stabilizer device that fixes the vessel to be bypassed and bypass surgery is performed while the heart is working. On the other hand, with the precision instruments developed and the experience gained, we started to perform these surgeries with small incisions. We now perform these surgeries under the armpit with a minimally invasive method in almost all coronary bypass surgeries. The logic of bypass surgery is to bridge the clogged coronary artery in such a way that blood goes beyond the occlusion. During this bridging, right or left mammary artery is used. Arterial grafts remain open for longer years than vein grafts taken from the leg.
