Three cases with May-Thurner syndrome: a possibly under-reported disorder.

The May-Thurner syndrome is an acquired stenosis of the left common iliac vein causing left lower leg edema, thigh discomfort, and deep venous thrombosis. This condition was first described by May and Thurner in 1956 in 22% of autopsy series. They concluded that it was the underlying factor for deep venous thrombosis on the left side. Here, we present three young female patients with May-Thurner syndrome, but without actual thrombosis. One of these patients was successfully treated with a Wall stent, and the other two patients underwent clinical follow-up with anticoagulant therapy.
