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.

A 62-year old man was referred to our hospital with endocarditis. Although the infection was improved by antibiotic therapy, he underwent surgery because of severe aortic and mitral valve regurgitation. Preoperative computed tomography revealed a pseudoaneurysm of 20 mm in diameter at the posterior wall of the ascending aorta. The non-coronary cusp was infected and there was a punched-out pseudoaneurysm at the ascending aorta adjacent to the sino-tubular junction. After resection of the aortic wall and the aortic valve, a modified Bentall operation with a composite graft and mitral valve plasty was performed. Postoperative whole body computed tomography revealed no other pseudoaneurysms. In case of endocarditis, we have to consider the possibility of aneurysm formation throughout the body.

A 71-year-old man had sudden onset of left lower limb swelling and consulted an orthopedic surgeon 14 days later. Venous echography demonstrated compression of the left iliac vein and the thrombus of the common iliac vein. After emergency admission, conservative therapy was given for 7 days, but the symptoms did not sufficiently diminish and a thrombus was also present. We therefore performed femoro-iliac cross-over vein bypass using a 10mm ringed ePTFE graft. Symptoms were completely improved and the graft was shown to be patent by echography after 3 months.
