Chronic Pulmonary Artery Pseudoaneurysm Associated With Patent Ductus Arteriosus and Endocarditis

Pulmonary artery pseudoaneurysms are rare, life-threatening conditions linked to trauma, infection, or congenital anomalies such as patent ductus arteriosus. A 40-year-old man with an untreated patent ductus arteriosus and endocarditis presented in mixed cardiogenic and septic shock. Imaging identified a large pseudoaneurysm, a restrictive patent ductus arteriosus, and severe aortic valve disease. He underwent successful open surgical repair with aortic valve replacement, ductus closure, and pseudoaneurysm resection using a pericardial patch. A surgical video documenting the procedure offers an educational resource for managing similar cases. This case emphasizes the importance of individualized surgical strategies and multidisciplinary care for optimizing outcomes in high-risk patients.
