Radical Endarterectomy of Severely Calcified Ascending Aorta Prevents Stroke During Open-heart Surgery

Abstract

In ten patients (7 women), mean age 73 years, with severely calcified ascending aorta, aortic valve and coronary artery disease were surgically treated after radical endarterectomy of the ascending aorta during cardiopulmonary bypass and with or without deep hypothermic total circulatory arrest. One patient died 10 days and one 11 months postoperatively of complications which neither directly nor indirectly could be attributed to the aortic endarterectomy. The eight surviving patients are doing well after follow-up averaging 16 months. CT scans 1 year postoperatively showed no aneurysmal dilation of the ascending aorta or aortic dissection distal to the endarterectomy site. Radical endarterectomy of calcified ascending aorta thus can be performed with relatively low mortality and stroke risk and may be considered in patients undergoing valve replacement and/or coronary artery bypass grafting.
