Giant pseudoaneurysm from Vieussens' arterial ring

Abstract

A giant coronary pseudoaneurysm of uncertain cause, arising from Vieussens' arterial ring, was preoperatively diagnosed in an oligosymptomatic female patient. Successful off-pump surgical excision without additional bypass grafting was performed. Difficulties in diagnostic algorithm, as well as possible cause and extremely rare localization were discussed. © 2004 by The Society of Thoracic Surgeons.
