Modified four-branched graft technique without circulatory arrest and antegrade thoracic endovascular aortic repair for extensive thoracic aorta reconstruction.

Abstract

A modified technique is described, using four-branched graft for proximal aortic repair without the need of deep hypothermic circulatory arrest, and simultaneously using antegrade stent-graft implantation for thoracic endovascular aortic repair of distal aorta in patients with extensive aortic aneurysm, acute type A aortic dissection, and chronic type B dissecting aneurysm. A good surgical field was obtained in 6 patients in this report, and no hospital mortality developed. The modified four-branched graft technique with no circulatory arrest provided good short-term outcome for proximal aorta repair, and the single-stage operation combined with antegrade thoracic endovascular aortic repair is feasible and effective to extend the repair down to the descending aorta.
