[A case of aneurysm of the descending thoracic aorta associated with Behçet's disease].

A 66-year-old male with Behçet's disease admitted again with hemoptysis. He underwent the resection and direct closure of descending aortic aneurysm 3 years ago, followed without the use of steroid. Chest CT scanning demonstrated a recurrent aneurysm of the descending aorta which was could not be detected on the previous CT only 23 days before. In the current operation, we performed resection, direct closure and wrapping of the aneurysm. The pathological examination showed a true aneurysm of Behçet's disease. The patient is free from recurrence for 17 months since the operation under steroid therapy.
