AbstractA 34-year-old male presented with an infected intralobar pulmonary sequestration of the left lower lobe. Aortography revealed bilateral anomalous systemic arteries, originating in the lower level of the descending thoracic aorta, to the lower lobe on each side. The portion of the right lower lobe, which was perfused by the anomalous systemic artery was seen otherwise normal in anatomy without any recognizable sequestered lung tissue. The patient underwent a left postero-lateral thoracotomy on June 22, 1994. Each aberrant artery was recognized to take off from a common branch of the descending aorta at the level of the diaphragm. A left lower lobectomy with division of the left aberrant artery as well as ligation of the right anomalous artery were done. A postoperative pulmonary perfusion scan depicted normal uptake of radioactivity in the right lower lobe, suggesting normal pulmonary arterial perfusion to the area receiving previously the anomalous systemic arterial flow. An anomalous systemic artery perfusing an otherwise normal lung can be classified as one of the forms of intralobar pulmonary sequestration and could be ligated without resection of the involved area of the lung.
