Isolated Left Subclavian Artery, Multiple Ventricular Septal Defects and Pulmonary Hypertension In A Child: A Case Report

Abstract

\n solated left subclavian artery is a rare congenital aortic arch anomaly in which the left subclavian artery is connected to the pulmonary artery via a patent Ductus Arteriosus or a remnant of it, instead of the arota. Generally, it is associated with the right aortic arch and other congenital heart defects, mostly tetralogy of Fallot. Isolated left subclavian artery can cause subclavian steal syndrome, pulmonary steal syndrome and size or blood pressure discrepancy between the two upper limbs. We present a 14-months-old infant with isolated left subclavian artery, multiple ventricular septal defects and pulmonary hypertension. To our knowledge, it is a rare anomaly which can influence the surgical planning and outcomes.
