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.
