Early Obliterated Cabrol Shunt: Culprit of Aortopulmonary Fistula in Large Pseudoaneurysm after Bentall Procedure

Aortopulmonary fistula secondary to a large pseudoaneurysm after a Bentall procedure is a rare but complex complication. Herein, we report a case of Cabrol shunt obliteration and pseudoaneurysm formation three months after a Bentall procedure. The patient also presented with congestive heart failure due to an aortopulmonary fistula six years later. Surgery was successfully performed to repair the dehiscence of the biliteral coronary ostia and the aortopulmonary fistula, and to replace the ascending aorta. Postoperatively, the patient recovered uneventfully.
