title: Innominate vein vascular ring provides novel insight into systemic venous embryogenesis.
abstract: Anomalies of the innominate vein are uncommon in congenital cardiac disease. We report a case of duplicate innominate veins forming a vascular ring encircling the ascending aorta. We postulate that this vascular ring represents the failure of both a dorsal and ventral precardinal anastomosis to regress.
