Innominate artery aneurysm: Axial reconstruction via a cervical approach

Abstract

True aneurysms of the innominate artery are rare. Successful axial reconstruction in the past has required a combined cervical and transthoracic approach with placement of a prosthetic graft. We describe herein the occurrence of an innominate artery aneurysm that extended to and involved the proximal common carotid artery and subclavian artery in a 63-year-old woman. The patient presented with thomboembolic sequelae in her fingertips and had a pulseless upper extremity. Successful aneurysmectomy and axial reconstruction with a bifurcated graft was achieved by using cervical exposure alone. A subsequent staged revascularization of the upper extremity was successfully accomplished with a brachial to radial artery bypass and ulnar artery transposition.
