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.
