Two cases of an anomalous systemic arterial supply to the basal segments of the left lower lobe without pulmonary wequestration are presented. In the first case, a preoperative diagnosis was made by chest CT, and confirmed by angiograpy, in a 22-year old man who had a recurrent hemoptysis. There was systemic arterial supply that originated from the thoracic descending aorta and no pulmonary arterial supply to the basilar segment of the left lower lobe. However, the pulmonary parenchyma was normal without sequestration. Ligation of the abnormal artery and a left lower lobectomy were performed without complication. In the second case, there were characteristic features of this anomaly on chest CT and the angiogram in a 31-year-old man with symptoms of hemoptysis. The patient refused surgery.
Key Words: Anomalous systemic arterial supply, pulmonary sequestration
