Acute superior vena cava syndrome after rupture of Kommerell's diverticulum: a case report.

Abstract

Kommerell's diverticulum, a rare congenital aortic anomaly, is dilatation at the region in which an aberrant subclavian artery branches from either a left-sided or right-sided thoracic aorta. We report a rare case of acute superior vena cava syndrome that developed in a young healthy male patient who presented to the emergency department in imminent respiratory arrest after rupture of this diverticulum.
