Endovascular repair of a subclavian artery aneurysm in Behçet's disease.

Behçet's disease is a rare, chronic, relapsing condition comprising multisystemic inflammatory dysfunction, whereas subclavian artery aneurysm is a rare peripheral atherosclerotic aneurysm that has a high risk of rupture or embolization. Herein, we report the case of a 32-year-old man with Behçet's disease who developed pseudoaneurysm of the left subclavian artery. He was admitted to the emergency department due to radiating pain in the left neck and shoulder. Endovascular repair was performed, and high-dose anti-inflammatory therapy was begun. Ultrasonography performed on postoperative day 3 showed good stent patency. Endovascular therapy may be a safe and effective treatment for arterial aneurysm in patients with Behçet's disease.
