Type I hybrid aortic arch debranching without cardiopulmonary bypass

Abstract

Aortic arch aneurysms represent a major challenge as the involvement of the supra-aortic vessels demands a complex surgical technique. Since the advent of endovascular aortic repair, hybrid treatment of aortic arch disease has emerged in recent years. The procedure consists of surgical bypass of the supra-aortic vessels followed by exclusion of the aneurysm with an endograft. This hybrid method is known as debranching and, briefly, consists in performing bypasses between the ascending aorta and the brachiocephalic artery, the left carotid artery and possibly the left subclavian artery without cardiopulmonary bypass, in order to advance an endograft to cover the entire lumen of the aneurysm.
The aim of this paper is to describe the surgical technique of type I hybrid debranching without cardiopulmonary bypass and antegrade endograft delivery to treat aortic arch aneurysms.
