Simplified Zone 2 Arch Repair Using a Trifurcated Graft for Acute Type A Dissection.

Overview

We report a simplified zone 2 arch repair using a trifurcated graft for acute type A aortic dissection. The right axillary artery is cannulated. After completion of proximal aortic repair using a 1-branched graft, a trifurcated graft is anastomosed to the ascending graft just above the proximal suture line or coronary buttons in case of Bentall procedure. Distal aortic anastomosis is performed at the zone 2 level under unilateral antegrade cerebral perfusion. Full cardiopulmonary bypass flow is resumed via the right axillary artery and ascending graft using both Y-shaped arterial limbs. The left common carotid and innominate arteries are sequentially anastomosed.
