Inominant Artery (Anomalous):
Clinical:
The right inominate artery (in a patient with a left arch) arises more
distally than usual- typically to the left of the trachea. As the vessel
courses to the right, it may create an anterior tracheal indentation and
occasionally these patients may be symptomatic. This anomaly is noted somewhat
more frequently in children with underlying congenital heart disease. Treatment
consists of surgical reposition of the vessel for symptomatic patients.
