[Total aortic arch replacement through a median approach].

Seven patients underwent total aortic arch replacement only through a median approach since March 1990, in our institute. The woven Dacron graft with three side arm branches were used. After the proximal anastomosis at the ascending aorta, open distal anastomosis at the descending aorta was performed in five cases, under circulatory arrest of the lower body using separate perfusion to the brain. In two cases with true aneurysms involving the aortic arch, occlusion balloon catheters were employed for distal anastomosis. The anastomosis of the arch vessels was performed after coronary reperfusion. There was no early operative death, and our results demonstrate that total arch replacement can be safely accomplished through a median approach with an acceptably low operative risk.
