Don't trust a vein graft to treat carotid aneurysm in patients with Behçet disease

Extracranial carotid aneurysm is a rare vascular manifestation of Behçet disease. To our knowledge, only 32 cases have been reported. This article presents a complex case of a 28-year-old man who was first treated by vein graft reconstruction. At 12 months of follow-up, a nonanastomotic false aneurysm of the vein graft occurred and was treated by interposition of prosthetic graft. Two months later, an anastomotic pseudoaneurysm between the two grafts was excluded by two stent grafts. Based on our experience and a review of the literature, we compared the outcomes of prosthetic and autologous vein reconstructions and discussed the role of carotid ligation and immunosuppressive treatment.
