Prenatal ultrasound diagnosis of fetal isolated left innominate vein under the aortic arch: A case report

Abstract

Abnormalities of the left innominate vein beneath the aortic arch are exceedingly rare. While they may not exhibit overt clinical symptoms, misdiagnosis, or failure to diagnose can significantly complicate and increase the risk associated with cardiac interventional procedures.

Keywords: fetus; left innominate vein under aortic arch; prenatal echocardiography.
