Introduction
A Kommerell diverticulum (KD) is a complex congenital anomaly of the aorta. It is asymptomatic but has a risk of a rupture or dissection. Several options have been described to treat an aberrant subclavian artery (ASA) and associated KD. We report a rare case of a successful staged hybrid open repair of a KD and two thoracic saccular aortic aneurysms.
