[A case of pseudoaneurysm of the thoracic aorta with Behçet's disease].

A 54-year-old female with incomplete type of Behçet's disease was operated on because of impending rupture of the thoracic aneurysm. There was a saccular pseudoaneurysm below the left subclavian artery, and a punched out lesion of the aorta was recognized. The defect of the aortic wall was closed with a PTFE patch. Before and after the operation, we have given prednisolone. The postoperative course was uneventful. Two years later, there was no recurrence of pseudoaneurysm near the PTFE patch. In many reports, aneurysms of Behçet's disease are saccular pseudoaneurysms, and have high incidence of complications about anastomosis postoperatively. We need a further follow-up about this patient.
