Right Aortic Arch With Aberrant Left Subclavian Artery and Anomalous Origin of Right Pulmonary Artery From Ascending Aorta

Abstract

The authors report a case of a neonate that was operated on with the diagnosis of right aortic arch and aberrant left subclavian artery and anomalous origin of right pulmonary artery from ascending aorta. Computed tomography (CT) scan suggested double aortic arch and cardiac catheterization suggested anomalous origin of right pulmonary artery from ascending aorta versus aorto-pulmonary window. The final diagnosis was made at the operation. There was a right aortic arch and aberrant left subclavian artery and persistent ductus arteriosus. Surgical repair consisted of section of the ductus arteriosus and reimplantation of the right pulmonary artery in the main pulmonary artery.

Right Aortic Arch with a Retroesophageal Left Subclavian Artery and an Anomalous Origin of the Pulmonary Artery from the Aorta

“…We diagnosed the neonate with right aortic arch with retroesophageal LSCA and anomalous origin of the pulmonary artery from the aorta using echocardiography and CT, and we treated the condition surgically. This variant has been reported by Hamzeh et al [ 1 ], but our case showed some differences in terms of the presence of an intracardiac anomaly (ASD) and DiGeorge syndrome. Congenital anomalies of the aortic arch range from asymptomatic normal variations in the arch vessel branch pattern to symptomatic vascular rings, stenosis, and arch interruptions.…”
