title: Rigid intraluminal prosthesis for replacement of thoracic and abdominal aorta.
abstract: During the past seven years, 80 patients have undergone aortic substitution using a rigid intraluminal prosthesis. There were 9 early deaths. The procedures involved 32 dissecting aneurysms (18 ascending and 14 descending), 16 atherosclerotic aneurysms of the ascending aorta and 13 atherosclerotic aneurysms of the descending aorta, 3 thoracoabdominal aneurysms, 2 arch aneurysms, and 14 abdominal aortic aneurysms. There was one early dislodgment of the rings necessitating reoperation, but no other early complications related to the procedure. In the follow-up period (mean, 25 months) there were 6 late deaths. One occurred 6 months after operation in a patient with empyema. There were no late complications of thrombosis, erosion, pseudoaneurysm formation, or hemorrhage. The follow-up data are extremely encouraging. We now are using this device whenever possible in all substitutions of the aorta, although in approximately 40% of patients, it is necessary to remove one of the spools and suture either the proximal or distal end of the graft owing to the close proximity of the aneurysm to the coronary ostia or the origin of the subclavian artery. Important techniques of insertion and postoperative angiograms are presented.
