A novel technique of coronary revascularization in porcelain aorta: report of two cases.
Severe atherosclerosis of the distal ascending aorta increases the risk of intraoperative stroke during coronary artery bypass. More than one in situ arterial graft is required to avoid aortic manipulation during proximal anastomosis. The application of bilateral internal thoracic arteries is a good choice, but it also carries the risk of sternal wound complications. Using a composite graft constructed with a partially harvested in situ right internal thoracic artery graft and another vascular conduit prevents extreme ischemia of the sternum. This study describes the experience of successful coronary revascularization using bilateral internal thoracic arteries and modified with a composite graft in two patients with a severely atherosclerotic ascending aorta.
