Abstract
Surgery for aneurysms of the aorta is a formidable challenge especially when these aneurysms involve the ascending aorta and the transverse arch. We have used the technique of cardiopulmonary bypass, profound hypothermia and total circulatory arrest with marked reduction in neurological complications. Availability of albumin coated and gelatin sealed grafts, as well as blood components, has reduced the associated bleeding problems. Ninety-six patients with aneurysms of the ascending aorta and the transverse arch were operated upon between 1983 and 1993. Patients with aneurysms of the sinus of Valsalva have not been included in this study. Syphilitic pathology was predominant in the group with late presentation of very large aneurysms. The mortality was 17.71% and was largely due to low cardiac output, prolonged ventilatory support, lung infections, and mediastinitis.
