Mycotic pseudoaneurysm of the ascending aorta caused by Escherichia coli.
An 81-year old woman with high fever and a history of hospital admission because of pyelonephritis 3 months previously was transferred to our hospital. Contrast-enhanced computed tomography revealed a mycotic pseudoaneurysm in the ascending aorta and a massive pericardial effusion. We resected the ascending aorta and the proximal part of the brachiocephalic artery and performed in situ revascularization with a prosthetic vascular graft. Bacterial examination proved that the causative micro-organism was Escherichia coli. The prosthetic graft was wrapped with a pedicled omentum following completion of the aortic reconstruction. Her postoperative course was uneventful. She was discharged from the hospital 1 month postoperatively.
