Unusual cause of absent pulse in one arm: Isolated subclavian artery

Asian Cardiovasc Thorac Ann. 2015 May;23(4):439-42. doi: 10.1177/0218492313513593. Epub 2013 Nov 28.

Abstract

Isolated origin of the subclavian artery is a congenital anomaly of the aortic arch in which one subclavian artery originates from the homolateral pulmonary artery through the ductus arteriosus. Isolated right subclavian artery with left-sided aortic arch is extremely rare. We report a case of isolated right subclavian artery from the right pulmonary artery via a right-sided ductus arteriosus in a 4-year-old girl. The child presented with subclavian pulmonary steal with perfusion of the right arm and lung from the right vertebral and carotid arteries. She underwent successful surgical repair.

Keywords: Ductus arteriosus; congenital; heart defects; patent; subclavian artery.
