May-Thurner syndrome associated with Klippel-Trenaunay syndrome.

Abstract

We present an unusual case of a 23-year-old man who had symptomatic lower extremity varicosities that have been present since birth. He was complaining of pain and swelling of several years duration. Evaluation revealed Klippel-Trenaunay syndrome with associated compression of the left common iliac vein by the overriding left common iliac artery (May-Thurner syndrome). The patient was treated with left common iliac vein stenting followed by high ligation and inversion stripping of his grossly incompetent left small saphenous vein, stripping of his aberrant left lateral embryonic veins, and also by multiple stab phlebectomies, with excellent early result.
