title: Anomalous systemic arterial supply to the Basal segments of the lung: feasible thoracoscopic surgery.
abstract: BACKGROUND
  Anomalous systemic arterial supply to the basal segments of the lung is a rare anomaly. This study aimed to evaluate the outcomes of thoracoscopic surgery for this anomaly.
  
  
  METHODS
  We reviewed patients who underwent thoracoscopic surgery for anomalous systemic arterial supply to the basal segments of the lung between October 2007 and September 2012 at our institution.
  
  
  RESULTS
  Four patients (mean age 37.5 years; range, 22 to 54) underwent thoracoscopic surgery for anomalous systemic arterial supply to the basal segments of the lung. The mean diameter of the anomalous arteries was 14 mm (range, 10 to 16 mm). Two patients underwent thoracoscopic segmentectomy, 1 of whom had a complicated anomaly that necessitated conversion to thoracotomy. The other 2 patients underwent thoracoscopic lower lobectomy of the left lung. One of them had an aneurysm in the anomalous artery; therefore, endovascular devices were kept on standby in case massive hemorrhage occurred. The anomalous arteries were divided uneventfully using a vascular stapler in all patients. No patient had severe postoperative complications.
  
  
  CONCLUSIONS
  Thoracoscopic surgery for anomalous systemic arterial supply to the basal segments of the lung is feasible, safe, and minimally invasive, with confirmed effectiveness in typical cases.
