ANGIOGRAPHIC DEMONSTRATION OF ANOMALOUS ORIGIN OF THE SUBCLAVIAN ARTERY IN INTERRUPTION OF THE AORTIC ARCH

Abstract

Two cases of interruption of the aortic arch with angiographic demonstration of anomalous subclavian arteries are reported. Abnormal differentiation in a specific region of the embryonic arch system occurring during the second month of fetal life accounts for the development of interruption of the aortic arch and associated anomalies. Clinically, patients with interruption of the aortic arch present with nonspecific signs of congestive heart failure. Differential cyanosis is not usually noted. Selective angiocardiography is the most precise method for establishment of the correct diagnosis in the living infant.
