CTICasesIatrogenic Aortic Root Pseudoaneurysm
Imaging findings
CT angiography in a patient with a prior aortic valve replacement and healed sternotomy demonstrates a giant pseudoaneurysm at the aortic root near the origin of the right coronary artery, with an associated large right hemothorax, occurring after a recent coronary angiogram.
Key takeaways
Aortic root pseudoaneurysm is a rare, dangerous complication of cardiac surgery or percutaneous coronary interventions. Cannulation or catheter injury to the sinus of Valsalva can lead to a contained hematoma or pseudoaneurysm, which carries a high risk of rupture and hemothorax.
