Transcatheter Embolization of Pulmonary Artery Aneurysm With Vascular Plug in Behcet's Disease: A Case Report

Pulmonary artery aneurysm (PAA) is one of the pulmonary manifestations of Behçet's disease, with hemoptysis as the primary symptom, carrying a high mortality risk. Treatment options include medical therapy, transcatheter embolization, and surgery. We report a case of a wide-neck PAA in a patient with Behçet's disease who did not respond to immunosuppressive therapy and was successfully treated with endovascular embolization using a vascular plug. The patient remained asymptomatic, with no recurrence of hemoptysis post-procedure. Treatment selection depends on aneurysm characteristics and institutional expertise. Vascular plugs offer a valuable alternative, particularly for wide-neck aneurysms, ensuring effective and durable occlusion.
