OBJECTIVES: We sought to describe the midterm results of extensive primary repair of the thoracic aorta by means of the modified @entity7105 trunk technique with a stent graft for acute @entity1580 , particularly the changes of the false lumen shown by enhanced computed tomographic scanning. METHODS: The subjects were 35 consecutive @entity1 who received arch replacement with open stent grafting for type A acute aortic dissection between December 1997 and April 2002. The mean follow-up period was 55 months (range, 30-83 months). Computed tomographic scanning was performed at 1, 3, 12, and 36 months postoperatively to detect @entity715 and obliteration of the false lumen after its exclusion by the stent graft. The diameter of the aorta was measured at 3 levels: the distal edge of the stent graft, the diaphragm, and the origin of the superior mesenteric artery. RESULTS: Two @entity1 died in the initial operation, but no @entity1 required additional surgical treatment of the thoracic aorta. The mean diameter of the stent grafts was 26.2 mm, and the mean length was 8.9 cm. @entity715 formation in the false lumen was recognized at the distal edge of the graft in all @entity1 , at the diaphragmatic level in 26 @entity1 , and at the superior mesenteric artery level in 15 @entity1 . Obliteration of the false lumen was recognized at the distal edge of the graft in all @entity1 , at the diaphragmatic level in 20 @entity1 , and at the superior mesenteric artery level in 15 @entity1 . The aorta distal to the stent graft showed minimal changes. CONCLUSIONS: In @entity1 with acute type A aortic dissections, it is possible to perform extensive primary repair of the thoracic aorta with relative safety by using a synthetic graft with a self-expanding stent, and this method might reduce the necessity of further operations not only for the distal descending aorta but also for the thoracoabdominal aorta.
