CTICasesRuptured Post-Operative Aortic Root Pseudoaneurysm
Imaging findings
Immediate post-operative CT angiography following a type A aortic dissection repair (including aortic valve, root, and ascending aortic graft replacement) shows a tiny, localized pseudoaneurysm at the distal suture line of the aortic root graft. On a follow-up gated CT angiography obtained four months later, this small pseudoaneurysm has ruptured, demonstrating a large, blood-filled cavity with contrast extravasation extending along the length of the ascending aortic graft, representing a contained rupture held by the adventitia.
Key takeaways
Small, iatrogenic pseudoaneurysms at graft anastomosis or suture sites are relatively common incidental findings on post-operative imaging after aortic reconstruction. While many remain stable and are managed conservatively, they carry a risk of progressive enlargement and catastrophic rupture, highlighting the necessity of careful surveillance imaging.
