T-graft technique under antegrade cerebral perfusion for aortic arch aneurysm.

Abstract

We have devised a T-graft technique for selected extensive aortic arch replacement under antegrade cerebral perfusion. Under hypothermic circulatory arrest using antegrade cerebral perfusion, one graft was island-anastomosed to the supraaortic arteries. The other graft was anastomosed to the descending aorta. Proximal and distal grafts were then end-to-side anastomosed in a T-shape. During rewarming, the ascending aorta and proximal graft were anastomosed. The surgical field was good in the 6 patients included in this report. No perioperative deaths or serious complications were encountered. This procedure was effective for patients with extensive aortic arch aneurysm and relatively intact orifices of the supraaortic arteries.
