Anomalous systemic arterial supply to the basal segments of the lung with three aberrant arteries.

We report a case of anomalous systemic arterial supply with three aberrant arteries supplying the basal segments of the right lung. There is no published report of a patient of anomalous systemic arterial supply to the basal segments with three aberrant arteries. Transverse computed tomography (CT) showed one aberrant artery in the right lower lobe, and preoperative three-dimensional CT showed three aberrant arteries, which provided detailed information and assisted in the thoracoscopic surgery. The patient underwent a complete thoracoscopic right lower lobectomy.
