Coronary artery bypass graft ( CABG ) is a surgical procedure to restore normal blood flow to an obstructed coronary artery. CABG belongs to very frequent procedures carried out at the Glenfield Hospital. We operate several hundred of CABG a year. CABG is usually performed with the heart stopped, using cardiopulmonary circuit / machine to maintain blood circulation in the rest of the patient's body.
A normal coronary artery transports blood to the heart muscle itself, not through the main circulatory system. If blocked or significantly narrow, this condition may cause chest pain - angina, which would be the leading symptom. Partially limited blood flow through one or more coronary arteries or complete occlusion may damage the muscle of the heart. To prevent these changes to happen, bypass enables the blood to reach beyond the obstacle in flow. The procedure typically takes 3 to 4 hours under general anesthesia and approx one week of in-hospital recovery.
