title: Anomalous systemic arterial supply to the basal segments of the left lung with two aberrant arteries.
abstract: A 30-year-old man was admitted to our hospital because of hemoptysis. Digital subtraction aortography revealed an anomalous systemic artery (10 mm diameter) from the descending thoracic aorta to the basal segments of the left lung. The presence of another smaller aberrant artery from the abdominal aorta was strongly suspected on the basis of aortography. We confirmed the presence of a smaller aberrant artery (3 mm diameter) traversing the pulmonary ligament after thoracotomy. We performed left lower lobectomy with resection of the two aberrant arteries via posterolateral thoracotomy with a favorable postoperative outcome. Although it is rare, the possibility of the presence of several aberrant arteries should be considered in anomalous systemic arterial supply to the basal segment of the left lung. Preoperative identification of aberrant arteries was useful for a safe operative procedure.
