Symptomatic May-Thurner Syndrome Without Deep Venous Thrombosis

The authors present a case of symptomatic May-Thurner syndrome in the absence of a deep venous thrombosis. This is an unusual case, as most cases are diagnosed with a deep venous thrombosis as the underlying finding. The clinical presentation and suggested diagnostic workup are discussed. A key point is the need to consider this frequently under-diagnosed condition. Optimal management is often with a stent, but if not diagnosed, the patient can develop unnecessary clot burden, be placed on lifelong anticoagulation, or both.
