Late results of operation for acute aortic dissection producing aortic insufficiency.
Since July, 1970, 8 patients with acute dissecting aneurysms of the ascending aorta producing aortic insufficiency have undergone immediate operation employing a technique in which the origin of the dissection is resected, the dissected base of the aorta is lined with nondistensible prosthetic cloth for support, and the native aortic valve is resuspended. Aortic continuity is then reestablished with end-to-end anastomosis or use of a short segment of woven graft (not necessarily circumferential). There were no operative deaths. Mean follow-up has been 60 months (range, 25 to 82 months). One late death has occurred (cerebral hemorrhage at 48 months); of the remaining 7 patients, 2 have faint murmurs of aortic insufficiency, but all are in New York Heart Association Functional Class I. This technique of aortic reconstruction in acute ascending dissections allows preservation of the native aortic valve while preventing late aortic root dilatation or major valve insufficiency.
