Anomalous Origin of the Right Pulmonary Artery from the Ascending Aorta in a 10-Day-Old Boy: A Case Report

Anomalous origin of the right pulmonary artery from the ascending aorta is a rare anomaly, comprising approximately 0.1% of all congenital heart diseases. Patients suffered congestive heart failure in infancy, and some patients will experience progressive pulmonary vascular disease without surgical repair. In patients of this disease, early surgical intervention is generally advised and has demonstrated a high level of safety and efficacy, yielding excellent outcomes. We report a unique case involving a 10-day-old boy, characterized by the rare anomalous origination of the right pulmonary artery from the ascending aorta. This case is further complicated by the presence of a patent ductus arteriosus (PDA) and a right descending aorta. The ligation of the PDA and reimplantation of the right pulmonary artery (RPA) were successfully performed. The patient exhibited a favorable recovery trajectory postoperatively.
