title: Aberrant right subclavian artery associated with common carotid trunk. A rare cause of vascular ring.
abstract: We have reviewed four cases of incomplete vascular rings caused by the presence of a common carotid trunk from which arose both carotid arteries associated with an aberrant right subclavian artery. The patients were aged between 3 and 9 months. All patients presented with recurrent respiratory tract infections. Three patients showed signs of malnutrition and failure to thrive caused by episodes of bronchial aspiration from extrinsic compression of the oesophagus. One patient presented with dyspnoea induced by feeding and another had stridor. A common carotid trunk associated with an aberrant subclavian artery was confirmed in all cases. No other associated anomaly was observed in any patient. Ligature and section of the anomalous right subclavian artery was performed in all patients. The low incidence of this type of vascular ring, its physiopathological mechanism and surgical management are discussed.
