Late Giant Aortic Pseudoaneurysm Following Iatrogenic Aortic Dissection.

Abstract

Aortic pseudoaneurysm occurs in 10 to 24% of patients after acute type A aortic dissection repair. We report the case of a 72-year-old female who developed an intraoperative iatrogenic ascending aortic dissection following mitral valve repair. A giant ascending aortic pseudoaneurysm was detected on follow-up imaging. This case emphasizes the importance of close radiological surveillance following acute aortic dissection repair.
