Anomalous Systemic Arterial Supply to Normal Basal Segments of the Left Lower Lobe of the Lung: Therapeutic Implication

Abstract

We describe a 5-month old infant who presented with a continuous murmur and enlargement of the left heart. The patient's diagnosis was an anomalous systemic arterial supply to basal segments of the left lower lobe characterized by a lack of a pulmonary arterial supply. This condition was treated without lobectomy. To our knowledge, this report is the first to describe an anomalous systemic arterial supply to basal segments of the lower lobe of the left lung with a single arterial supply that was treated in childhood without lung resection. Our case offers an alternative treatment to surgical lobectomy for this abnormality.
