title: Isolation of Left Common Carotid Artery with Its Origin Proximal to Patent Ductus Arteriosus Presenting in Adult Age.
abstract: Anomalies of aortic arch are a common occurrence. Such anomalies of right sided aortic arch with its various branching patterns are of clinical importance. Rarer anomalies include isolation (deficient connection) of either left subclavian artery or left common carotid artery; that is, they do not have their origin from aorta or its major branches. We present a case of an 18-year-old male who presented with gradual onset pulsatile swelling with bruit in neck on left side and was evaluated by CT brain and neck angiography. CT angiography revealed right sided aortic arch with aberrant left subclavian artery and isolated left common carotid artery. Very few cases of such an anomaly have been documented in the literature but none in an adult.
