Rigid intraluminal prosthesis for replacement of thoracic and abdominal aorta

From December 1976 to April 1983, 55 patients underwent operations in which intraluminal ring grafts were used for replacement of thoracic and abdominal aortic aneurysms. Twenty-eight patients had dissections, and 11 had ascending aneurysms. There were 10 descending aneurysms; three of these were traumatic. There were two arch aneurysms, three abdominal aneurysms, and one thoracoabdominal aneurysm. The follow-up period was 78 months with a mean follow-up period of 24 months. There were six postoperative deaths and six late deaths. No evidence of complications of thrombosis, migration, erosion, or pseudoaneurysm resulting from the ring within the 78-month follow-up period was seen, and we conclude that this is a safe, reliable, quick method for replacement of the aorta in certain well-defined situations.
