Operation for infected thrombus in the false lumen after ascending aortic repair for acute aortic dissection

Abstract

Background: Aortic dissection requires operation for some reasons. Methods: We experienced a case for infected thrombus caused by Escherichia coli in the false lumen of the descending aorta 3 years after ascending aortic replacement for acute aortic dissection. Results: A deep sternal wound infection caused by Staphylococcus species after the initial surgery had been successfully treated with both administration of antibiotics for 8 weeks and omental transfer. Replacement of the descending aorta resulted in successful outcomes. Conclusion: A thrombosed false lumen with a low blood flow may be vulnerable to bacteremia.
