Anomalous systemic arterial supply to normal basal segments of the lung

—Two cases of segmentectomy by video-assisted thoracoscopic surgery—

Abstract

We experienced 2 cases of segmentectomy for anomalous systemic arterial supply to normal basal segments of the lung by video-assisted thoracoscopic surgery (VATS). Segmentectomy conserving the normal lung area enabled preservation of the respiratory function with radical cure. The VATS procedure with minithoracotomy was minimally invasive and appropriate for safety. Case 1: A 29-year-old female was diagnosed with an anomalous systemic arterial supply to normal basal segments of the lung, and the aberrant artery distributed to the basal segments of the left lower lobe. Left basal segmentectomy was performed by VATS. Case 2: A 36-year-old female was diagnosed with an anomalous systemic arterial supply to normal basal segments of the lung, and the aberrant artery was supplying the right S⁹ and S¹⁰. Right S⁹+S¹⁰ segmentectomy was performed by VATS.
