[...]. Pseudoaneurysm at Cannulation Site Post-CABG. CTICases. Published August 28, 2015. https://str-case-explorer.pages.dev/c/r8z9v
Imaging findings
Non-contrast CT shows soft tissue in the anterior mediastinum adjacent to the ascending aorta. Contrast CT reveals a pseudoaneurysm arising from the anterior aspect of the ascending aorta. A felt pledge is visible on non-contrast CT, which is an arterial cannulation site for cardiopulmonary bypass. Another linear opacity, likely another felt pledge from a cardioplegia or arterial cannulation site, is seen adjacent to the pseudoaneurysm.
Key takeaways
This case demonstrates a pseudoaneurysm at a cannulation site following CABG. Knowledge of surgical anatomy, including the appearance and location of felt pledges from cardiopulmonary bypass cannulation sites, is crucial for accurate diagnosis and to avoid misinterpretation of mediastinal masses, preventing unnecessary biopsies. The pseudoaneurysm was planned for elective repair.
