From: Imaging of the aortic root on high-pitch non-gated and ECG-gated CT: awareness is the key!
A 58-year-old female post-op day 10 status post supracoronary ascending aorta replacement with graft repair and concern of pseudoaneurysm on a pulmonary embolism rule-out CT (not shown). Axial (a) and sagittal (b) high-pitch CTA images show a smooth contrast filled outpouching from proximal graft (white arrow) near to the anastomosis (black arrow in a). This smooth outpouching is a normal post-operative appearance, related to over sewn reperfusion catheter stump from cardiopulmonary bypass during surgery
