Repair of thoracic aortic aneurysm with bilateral aberrant subclavian artery

Abstract

We present a rare anatomical configuration of a 19-year-old woman, characterized by descending thoracic aortic aneurysm with right aberrant subclavian arteries with a Kommerell's diverticulum in a left aortic arch. The complexity of this vascular anomaly was accompanied by an anomalous origin of left subclavian artery. The patient underwent a single-stage open surgical repair via left thoracotomy under deep hypothermic circulatory arrest. The bilateral aberrant subclavian arteries were separately reconstructed in situ using hand-sewn branched grafts.
