Abstract
An intraluminal graft made of woven tubular Dacron with cloth-covered grooved rings at both ends is used to repair dissecting aneurysms of the thoracic aorta. White male patients(6) ranging in age from 31-69 yr with an average age of 55 yr were operated on with the use of this graft. Patients (3) had a dissecting aneurysm of the ascending aorta and 3 others had a dissecting aneurysm of the descending aorta. Total cardiopulmonary bypass was utilized in repairing dissecting aneurysms of the ascending aorta and left heart bypass was used in patients with dissecting aneurysms of the descending aorta. The basic technique consists in inserting the whole ringed graft into the true lumen of the dissected aorta and circumferentially ligating the aorta against the groove in the rings. The proximal ring of the graft effectively stabilized the flail aortic valve in 2 patients with aortic regurgitation associated with dissection of the ascending aorta. There were no hospital deaths. All patients are doing well 1 yr, 1 mo.-2 yr, 8 mo. after the operation.
