Atypical May-Thurner Syndrome Caused by Large Lumbar Osteophyte

Abstract

AbstractAn 82-year-old man presented to the emergency department with intermittent left lower extremity swelling for the last 4 to 5 months that limited his daily activities. The patient had a negative lower extremity venous duplex 3 months prior and had been treating symptoms with compression stockings but experienced no improvement. Venography showed venous outflow obstruction in his left common iliac vein and the etiology was confirmed to be a lumbar vertebral osteophyte compressing the vein. The patient underwent endovascular treatment with balloon venoplasty and stent placement over the lesion with return of adequate outflow. This report describes treatment of symptomatic left common iliac venous compression with endovascular therapy alone.
