Postoperative Lung Perfusion with Anomalous Origin of One Pulmonary Artery from the Aorta

Abstract

Pulmonary artery damage is difficult to estimate in a patient with one pulmonary artery from the aorta, and the pulmonary artery of anomalous origin is usually damaged. We describe a newborn patient with anomalous origin of the right pulmonary artery from the aorta who presented with significant lung perfusion at the anastomotic site 6 months postoperatively; the left/right perfusion ratio was 10:90 on a scintigram. The unbalanced left/right lung perfusion gradually improved over a number of years. In a newborn patient with anomalous origin of one pulmonary artery from the aorta, unbalanced lung perfusion may improve.
