Abstract:
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.
Insights
A mycotic pseudoaneurysm in the ascending aorta caused by Escherichia coli was successfully treated with aortic reconstruction and prosthetic vascular graft replacement. The patient recovered well after the surgical intervention.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Vascular Surgery
Background:
- A mycotic pseudoaneurysm is a rare but life-threatening complication of infection.
- Ascending aortic pseudoaneurysms require prompt surgical intervention to prevent rupture.
- Escherichia coli can cause serious infections, including vascular complications.
