The patient was a 68-year-old woman with chief complaints of severe lumbago, left lateral abdominal pain and high fever. Computer tomography(CT)at a local hospital showed a left psoas abscess and a low density area around the terminal aorta. Blood tests indicated a high inflammatory response and MSSA was detected in a blood culture. Control of the infection was first attempted with antibiotics, but CT showed a pseudoaneurysm at the terminal aorta, and therefore she was transferred to our hospital. We diagnosed infected abdominal aortic and left common iliac aneurysms complicated by an MSSA psoas abscess, and performed extra-anatomic reconstruction with axillo-bifemoral bypass, aneurysmectomy and omentopexy in the psoas abscess cavity. Because of massive intestinal edema and mesentery, we attempted temporary abdominal closure with the vacuum-assisted closure(VAC)technique, and finally succeeded in closing without abdominal infection in the 6th operation, 42 days after the first operation. Infected abdominal aortic aneurysm complicated by psoas abscess is extremely rare and life threatening. The VAC technique is very effective not only in avoiding abdominal compartment syndrome but also in avoiding abdominal infection.
