Subclavian venous aneurysm: endovascular treatment

Abstract

Few cases of venous aneurysm involving the subclavian vein have been reported in the literature to date, and all were treated conservatively or with surgical excision. The present report describes a 73-year-old woman with a pulmonary thromboembolism that likely originated from a large right subclavian vein aneurysm that was treated by percutaneous endovascular means. The technique involved placement of a self-expanding stent in the parent vein across the aneurysm, followed by filling of the lumen of the aneurysm with coils through a microcatheter. The patient has remained symptom-free at 18-month follow-up.
