Anomalous Origin of the Right Subclavian Artery from the Right Pulmonary Artery in a Patient with d-Transposition of the Great Arteries: Diagnosis and Surgical Treatment

Abstract

Anomalous origin of the right subclavian artery (AORSA) from the right pulmonary artery is a rare congenital anomaly usually diagnosed by computed tomography, magnetic resonance imaging, or angiography. We present a very rare case of diagnosis and surgical correction of AORSA coexisting with d-transposition of the great arteries in a newborn’s first hours of life. Due to the critical local hospital and patient conditions, additional cross-sectional imaging was not feasible. The diagnosis was suspected by clinical signs, confirmed by transthoracic echocardiogram, and the patient was urgently taken to the operating room. We discuss clinical and echocardiographic signs of this child with d-transposition of the great arteries and AORSA from the right pulmonary artery.
