A Giant Transsternal Aortic Pseudoaneurysm

Aortic pseudoaneurysm is a rare but life-threatening complication after a cardiac surgery. Potential mecha-nisms are suture dehiscence, iatrogenic trauma, and poor quality of aortic tissues. Most cases are diagnosed in the first months after the surgery and are caused by an infec-tious process. Here, we report a case of transsternal aortic pseudoaneurysm after an aortic valve replacement surgery, and we describe our surgical approach. This case is exceptional for its late timing and presentation with a pulsatile sternal mass.
