title: Aberrant right common carotid and subclavian arteries causing tracheoesophageal compression combined with persistent left superior vena cava--case report.
abstract: Vascular rings are a rare group of congenital thoracic vascular anomalies which are characterized by abnormal vascular structures that completely or incompletely encircle the trachea, esophagus, or both. We report the case of a vascular ring formed around the trachea and esophagus by aberrant right subclavian artery and aberrant right common carotid artery, associated with persistent left superior vena cava, complete absence of azygos vein, and with multiple nonvascular abnormalities. Recurrent pulmonary infections were the only clinical manifestation of this complex vascular anomaly. Our report represents a so-far-undescribed anatomic variation of the vascular ring that clinicians should be aware of.
