title: Simplified elephant trunk graft technique for aortic arch replacement.
abstract: We refined the elephant trunk graft to facilitate and reinforce the distal anastomosis in aortic replacement operations. A cuff is created in a single four-branch graft, which is used for the distal anastomosis; the trunk below the cuff is inserted into the distal aortic stump. This method is feasible for repairing extensive aortic aneurysm with a fragile wall and for treating acute aortic dissection where thromboocclusion of the remaining false lumen is desired.
