Anomalous right pulmonary artery from aorta, surgical approach case report and literature review

Abstract

Background: Anomalous origin of one pulmonary artery from the aorta is a rare congenital anomaly affecting the right pulmonary artery more than the left. These patients are at risk for the early development of significant pulmonary hypertension. Early surgical treatment has been proven safe with excellent results. The surgical approach and technique is challenging and should be decided ahead before the patient to surgery. Different techniques were described including direct reimplantation, conduit interposition, aortic ring flap. Aim: We present a neonate with anomalous origin of the right pulmonary artery from the aorta and discuss the surgical technique and complications in the literature.
