Isolation of left subclavian artery with reversal of neurological and hemodynamic abnormalities after percutaneous closure

Abstract

Isolation of left subclavian artery is a rare congenital anomaly. In this abnormality, the left subclavian artery arises from the homo-lateral pulmonary artery rather than from aorta. This condition is often diagnosed by angiography and treated by surgery. The authors present a case, which had vertebro-basilar insufficiency, subclavian steal phenomenon and pulmonary plethora. All these clinical signs disappeared by a simple percutaneous intervention.
