Objectives: To minimize any residual false lumen when operating on patients with an acute type A aortic dissection, we tried to perform extensive primary repair of the thoracic aorta with the modified elephant trunk technique. The early and midterm results of these surgical interventions are reported and evaluated.

Methods: Among the acute type A aortic dissections with extensive false lumen encountered since December 1997, 19 consecutive patients, 15 DeBakey type I with the tear in the ascending, transverse, or both aortas, and 4 DeBakey type III-D with the tear located in the descending aorta, underwent insertion of a synthetic graft with a distally anchored stent in the descending thoracic aorta.

Background: The late results of direct open stent grafting of the aortic arch for aortic arch repair have not been reported previously.

Methods: Between September 1997 and December 2000 19 patients underwent open stent grafting with carotid artery bypass for thoracic arteriosclerotic aneurysms (TAA) of the distal aortic arch. In addition, 21 patients underwent open stent grafting with total aortic arch replacement for Stanford type A acute aortic dissection and 7 patients underwent stenting with carotid bypass for Stanford type B chronic aortic dissection.
