Abstract

Subclavian artery aneurysms (SAAs) are rare, and their repair can be technically complex. We have reported the redo repair of a large, expanding, right SAA after primary repair consisting of total aortic arch replacement with bilateral subclavian artery ligation and bypass. The redo repair used claviculectomy to facilitate exposure, ligation of the right deep cervical and internal thoracic arteries from within the aneurysm sac, and revision of the previous axillary artery bypass that had thrombosed owing to the mass effect of the expanding SAA. Claviculectomy can facilitate repair of large SAAs that are poorly suited to more routine exposure approaches, with acceptable risk and functional outcomes.
