Iliac vein stenting for May Thurner syndrome

May-Thurner syndrome

May–Thurner syndrome (MTS), also known as the iliac vein compression syndrome, is a rare condition in which compression of the common venous outflow tract of the left lower extremity may cause discomfort, swelling, pain or blood clots, called deep venous thrombosis (DVT). The specific problem is compression of the left common iliac vein by the overlying right common iliac artery. This leads to pooling or stasis of blood, predisposing the individual to the formation of blood clots.

The diagnosis needs to be confirmed with a CT or MRI scan. Intravascular ultrasound is sometimes used.

Severe May–Thurner syndrome may require thrombolysis if there is a recent onset of thrombosis, followed by angioplasty and stenting of the iliac vein after confirming the diagnosis with a venogram or an intravascular ultrasound. A stent may be used to support the area from further compression following angioplasty.

This is currently being studied to determine if this will decrease the incidence of post-thrombotic syndrome.
