What is coronary artery bypass surgery?

kalp02Coronary artery bypass is an open heart surgery in which arteries or veins from elsewhere in the patient's body are grafted to the coronary arteries to bypass narrowing and improve the blood supply to the coronary circulation. Arteries or veins used in the surgery are easy to remove from their location and do not harm the blood circulation where they have been removed.
A typical example of an artery or graft is the mammary artery which extends down the interior chest wall, and an example of a vein is the saphenous vein which is a large, subcutaneous superficial vein extending from the tarsus to the inguen. Sometimes venous grafts can be prepared using dorsal veins of the leg or arm veins. Radial artery of forearm and gastric artery can also be used as arterial graft. 

Arterial and venous grafts are directly connected to coronary vessels on the surface of the heart during the surgery so that the grafts function as a bridge and ensure blood to flow beyond the stenosis.   

A heart and lung machine is often used to perform a coronary artery bypass surgery. This machine oxygenates the blood, and ensures blood flow to the body at a specific pressure to stop the heart. In this way, coronary arteries are bypassed.

What does a coronary artery bypass surgery provide?

A coronary artery bypass surgery increases the decreased blood flow to myocardium. This increased blood flow removes the chest pain (angina). In addition, it diminishes the fatigue and reduces excessive use of drugs, resulting in patients feeling better. Thus, the quality of life of the patients is improved. Bypass surgery extends the life time of persons with a severe coronary artery disease.  


Coronary bypass on a beating heart

Currently, patients who carry high risk rates for a heart surgery are gradually increasing among the ones who apply to Florence Nightingale Hospital which stands out to be the "referred hospital. Most of these patients apply to Florence Nightingale because the other hospitals are unable to operate these patients. In coronary bypass operations without using a heart-lung machine, i.e. without stopping the heart and lungs, the risk is considerably reduced in patients at pulmonary, cerebral and renal risk. With the use of state-of-the-art technology equipment, this surgery can be safely performed. More than 300 patients are successfully operated by this method at our clinic. In addition, the length of recovery and hospital stay is shortened.
