Catheter rehabilitation of occluded aberrant pulmonary artery

Abstract

A 10-year old girl underwent a CT angiogram to investigate right lung hypoplasia. This showed a normal bronchial tree, lung parenchyma and pulmonary venous drainage, but an absent right pulmonary artery. Cardiac catheterization with pulmonary vein wedge injections identified a disconnected hypoplastic right pulmonary artery system supplied by an occluded right-sided ductus arteriosus. Transcatheter recanalization of the ductus re-established right pulmonary artery flow and growth. Ultimately, this allowed for complete surgical repair and restoration of normal perfusion of the right lung, leading to complete functional rehabilitation. © 2013 The Author.
