We report a case of surgical treatment for idiopathic nonspecific inflammatory aneurysms of the abdominal aorta(AAA)with high-dose steroid therapy. The patient was a 35-year-old man who underwent steroid therapy(30mg/day prednisolone)for idiopathic nonspecific inflammatory AAA and right common iliac artery aneurysm(CIAA)for 5 months. However, the sizes of the aneurysms were slowly increasing, and they were sacculated types, so surgical replacement was performed. Before the operation we continued to give 30mg/day prednisolone, because decreasing the medicine made the c-reactive protein(CRP)value rise. Perioperatively the therapy continued, and the postoperative course was uneventful. With appropriate steroid therapy, replacement of idiopathic nonspecific inflammatory aneurysms of the abdominal aorta can be performed. It is also important to follow up the patient from long-term, to monitor for pseudoaneurysms from anastomosis or new aneurysms.
