Treatment of May–Thurner Syndrome in a Patient with an Iliac Artery Stent

May–Thurner syndrome (MTS) is a well-known condition where compression of the left iliac vein by the right iliac artery can lead to clinical manifestations of lower limb outflow obstruction and precipitate deep venous thrombosis (DVT). Endovascular intervention of the iliac arteries is a common procedure and is frequently done without any incidence of MTS. Although rare, it is important to recognise that the implantation of a device in the iliac arteries can precipitate iatrogenic MTS while also complicating the treatment of underlying venous pathology. With an increase in iliac artery interventions and the recognition of the contribution of iliac veins in lower limb pathology, clinicians need to be aware of the implications of treating venous disease. We present a case of the treatment of a long-standing iliac vein occlusion with an overlying stent in the iliac artery.
