Subclavian Venous Aneurysm: Endovascular Treatment

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.

Endovascular embolization of a muscular symptomatic arteriovenous malformation with Glubran 2 acrylic glue

Objective Few cases of muscle arteriovenous malformations have been reported in literature to date. Case report We report the case of a 32-year-old man presenting a muscle arteriovenous malformation involving the vastus lateralis muscle with recurrent episodes of pain. The patient was treated by transcatheter embolization with Glubran 2 acrylic glue. There were no periprocedural or subsequent clinical complications, the glue resulted in successful selective occlusion and the patient showed resolution of symptoms at the six-months follow-up. Conclusions Endovascular therapy has been shown to be beneficial in patients with high surgical risks and is the treatment of choice for arteriovenous malformation lesions that extend beyond the deep fascia and involve muscle, tendon, and bone. Glubran 2 constitutes a useful tool to attempt embolization of the muscle arteriovenous malformation nidus, with easier handling and promising results.
