Anomalous Origin of Left Common Carotid Artery From Left Pulmonary Artery in a 22q11.2 Deletion Syndrome Newborn With Right Aortic Arch and Aberrant Left Subclavian Artery

摘要

A2-month-old boy of 3.8 kg, born from consanguineous parents, was referred to our department for subaortic ventricular septal defect, right aortic arch and suspicion of vascular ring in 22q11.2 deletion syndrome. Computed tomography scan showed aberrant left subclavian artery with minimal compression on the esophagus and the rare and unexpected finding of isolated left common carotid artery (LCCA) arising from the left pulmonary artery via the residual left ductus arteriosus (Figure [A] through [C]), with small caliber of the vessel in its extracranial course.
