Kommerell's diverticulum is a rare congenital anomaly, consisting in aneurysmal dilatation at the origin of an aberrant subclavian artery. Depending on concomitant anatomical characteristics, different endovascular and open surgical procedures have been proposed. The following report describes the first single-stage hybrid repair of a type I Kommerell's diverticulum associated with an aortic arch aneurysm and anomalous origin of the brachiocephalic vessels by total aortic arch replacement with a composite frozen elephant trunk prosthesis and endovascular treatment of the right subclavian artery. This hybrid procedure may represent an alternative to more challenging open repairs when totally endovascular approach is unfeasible.
Keywords: Kommerell diverticulum; aortic arch aneurysm; hybrid approach.
