Isolated left common carotid artery in an infant with pulmonary atresia and intact ventricular septum

Jennifer L Cohen et al. Ann Pediatr Cardiol. 2019 May-Aug.

Abstract

Isolation of the left common carotid artery (LCCA) is a very rare congenital aortic arch anomaly. We present this finding in a female infant with pulmonary atresia and intact ventricular septum, with a clinical diagnosis of CHARGE syndrome. Cardiac catheterization revealed an anomalous origin of the LCCA from the pulmonary trunk, with retrograde filling of the pulmonary trunk seen during left subclavian artery injection. The LCCA was ligated during central shunt placement.

Keywords: Aortic arch anomaly; CHARGE syndrome; isolated carotid artery; pulmonary atresia with intact ventricular septum.

(a) Aortic arch injection demonstrating a right aortic arch with the right common carotid artery arising from the transverse arch. The main pulmonary artery fills via the patent ductus arteriosus, and the left common carotid artery origin form the main pulmonary artery is also seen. (b and c) Anteroposterior and lateral projections demonstrating the left common carotid artery arising from the superior portion of the main pulmonary artery near the bifurcation. (d) Left subclavian injection with retrograde flow seen in the left common carotid artery
