Abstract
We report a successful case of ruptured infected abdominal aortic aneurysm treated by endovascular repair and continuous irrigation of retroperitoneal abscess. A 77-year-old man, presenting with abdominal pain and loss of consciousness, was transferred under the diagnosis of ruptured abdominal aneurysm. High inflammatory reaction and thickened retroperitoneum was detected, and the diagnosis of ruptured infected abdominal aneurysm was made. We performed emergency surgery with endovascular treatment first, and drainage with irrigation of retroperitoneal space via subsequent laparotmy under same operation. Postoperatively infection was controlled by administration of the adequate antibiotics and continuous irrigation. However, postoperative CT showed a pseudoaneurysmal formation at proximal edge of stent graft, and additional endovascular repair was performed on the 21 postoperative day. The postoperative course was uneventful and no complication was detected during the 12 months follow up.
