The pulmonary sequestration is a rare congenital malformation of the lung, concerning about the abnormal feeding systemic artery, may happen a serious complication of bleeding during operation if not recognized before operation. We experienced a case of bilateral intralobar pulmonary sequestration preoperatively confirmed by aortogram. An Aortogram demonstrated a anomalous systemic artery arising from thoracic aorta just above the diaphragm. The artery bifurcated and supplied areas of both right and left lower lobes. On the operative field, left lower lobectomy was done with devision and ligation of left branch of anomalous artery and triple ligation of remained branch of anomalous artery was done. Postoperative course was uneventful. She was discharged on postoperative seventeenth day.
