Cystic Adventitial Disease of the Common Femoral Vein Successfully Treated with Resection, Synthetic Graft Reconstruction, and Fistula Creation.

Cystic adventitial disease (CAD) is a rare, benign disease of blood vessels which most commonly affects the popliteal artery. Less than 50 cases of CAD affecting veins have ever been described in the literature to date. We report the case of a 56-year-old woman who presented with unilateral lower extremity swelling and varicosities due to CAD of her common femoral vein. Resection and reconstruction with a venous interposition graft, employing a polytetrafluoroethylene graft and arteriovenous fistula in order to maintain venous bypass patency, were performed successfully. The patient recovered well without any evidence of recurrence or postoperative complications.
