Easy and Safe Total Debranching of Arch Aneurysms Using Axilloaxillary Arterial Bypass

Techniques used in hybrid repair of proximal aortic arch diseases are associated with perioperative complications such as cerebrovascular emboli. We present an easy and safe technique of total debranching thoracic endovascular aortic repair for arch diseases using axilloaxillary arterial bypass. The placement of the axilloaxillary arterial bypass enables perfusion of the brachiocephalic artery even when the artery is clamped. After reconstruction of the brachiocephalic artery and the left common carotid artery, the left subclavian artery is proximally ligated, and it is perfused through the bypass. This procedure is simple, safe, and useful for the prevention of neurologic complications.
