Novel repair of an external iliac vein aneurysm.

Aneurysms involving the venous system are a rare entity. We report the case of a 37-year-old woman who presented to us with activity-limiting left gluteal pain and who on consequent workup was found to have a left external iliac vein aneurysm in a setting of iliocavomegaly. She underwent successful treatment of her aneurysm with a novel approach that involved staple plication and resection of the aneurysm over a balloon mandrel. We discuss the presentation, diagnosis, and surgical technique adopted for the treatment of this uncommon condition.
