CTICasesInferior Epigastric Artery Pseudoaneurysm
Imaging findings
CT abdomen shows a large hematoma in the right abdominal wall containing a pseudoaneurysm arising from the right inferior epigastric artery, occurring shortly after cardiac catheterization.
Key takeaways
Pseudoaneurysms of the inferior epigastric artery are rare iatrogenic complications of femoral access during cardiac catheterization. They occur when the access needle is placed too high, accidentally cannulating the epigastric artery. They can be treated successfully via percutaneous thrombin injection.
