A 21-year-old woman was admitted to our hospital because an abnormal shadow in the left lower lung field was pointed out on a health check-up chest radiograph. Chest computed tomography (CT) showed an anomalous artery of 1.5 cm in diameter arising from the descending aorta, diagnosed as an anomalous systemic arterial supply to a normal basal segment of the left lung. The bronchial system was normal and the left basal segmental pulmonary veins were congested. Video-assisted thoracoscopic surgery was performed considering the risks of pulmonary hypertension and hemoptysis. Dissection of the anomalous artery without lung resection was performed because the lung tissue was radiographically normal without sequestration. The postoperative course was uneventful and she was discharged 3 days after the operation. Chest CT six months after the operation revealed only an organized bundle of the anomalous artery, without pseudoaneurysm or congestion in the left basal segment. We suggest that some patients with an anomalous systemic arterial supply to a normal basal segment of the lung could be successfully treated only by dissection of the anomalous artery with a stapler if the bronchial system is normal.
