title: Rare types of aortic arch anomalies.
abstract: Rare types of aortic arch malformations include isolation of the right or left subclavian arteries in conjunction with a left or right aortic arch respectively. Isolation of the innominate or carotid arteries and an aberrant left innominate artery may exist in association with a right aortic arch. Other anomalies are persistent fifth aortic arch, subclavian artery as the first branch of the aortic arch, pulmonary artery, and ductus arteriosus sling. The angiocardiographic features and embryology of each of these malformations are discussed.
