Migration of two venous stents into the right ventricle in a patient with May-Thurner syndrome.

May-Thurner syndrome is an uncommon process in which the right common iliac artery compresses the left common iliac vein, possibly resulting in pain, severe edema of the left leg or in left iliofemoral deep vein thrombosis [May R, Thurner J. The cause of the predominately sinistral occurrence of thrombosis of the pelvic veins. Angiology 1957; 8: 419-427 .]. Corrective surgical treatment requires extensive dissection. Therefore, endovascular venous stenting is currently used in these patients [Lamont JP, Pearl GJ, Patetsios P, Warner MT, Gable DR, Garrett W, et al. Prospective evaluation of endoluminal venous stents in the treatment of the May-Thurner syndrome. Ann Vasc Surg. 2002 Jan; 16(1): 61-4. Epub 2002 Jan 17 .]. We present a case of migration of two iliacal vein stents into the right ventricle in a patient with May-Thurner syndrome.
