Left-Sided Varicocele as a Rare Presentation of May-Thurner Syndrome

Varicocele is a leading cause of testosterone insufficiency and infertility in young males. In the majority of cases, successful treatment can be achieved by addressing reflux in the internal spermatic vein (ISV) and/or GV by a variety of surgical or endovascular approaches. In unusual cases, the culprit pathology may be reflux in the vein of the vas deferens, which unlike the ISV and GV, drains into the internal iliac vein. In such cases, iliac vein compression usually associated with MTS may result in varicocele. To our knowledge, this is the first report of refractory varicocele secondary to iliac vein compression successfully treated with endovenous stenting.
