Minimally Invasive Treatment of Kommerell's Diverticulum and Left Aberrant Subclavian Artery.

Kommerell's diverticulum is an aneurysmatic offspring of the left aberrant subclavian artery, which is a rare vascular anomaly of the aortic arch. Here, we present our less invasive approach to the repair of a symptomatic Kommerell's diverticulum in a 31-year-old patient, without the use of cardiopulmonary bypass.
