Abstract
A 44-year-old man with anomalous systemic arterial supply to the left basal lung was admitted to a hospital complaining of sudden hemoptysis. Chest computed tomography (CT) scan showed a high density area in the left S^8 segment and no abnormal findings in the bronchial trees. An aortogram revealed that an aberrant tortuous artery diverged from the descending aorta supplied to the left lower lobe. Under the diagnosis of pulmonary sequestration, the patient was referred to our hospital. We diagnosed anomalous systemic arterial supply to the left basal lung because an aberrant artery supplied the left basal segments and the sequestrated lung was not recognized. A left lower lobectomy and transection of the aberrant artery after its closure with a knifeless endostapling device were performed. The postoperative course was uneventful. We report here the successful treatment of anomalous systemic arterial supply to the left basal lung and the use of chest CT scan findings for the diagnosis of this disease. Operative procedures and histopathological findings were also discussed.
