Thoracoscopic segmentectomy for congenital pulmonary airway malformation arising in a lung with an accessory fissure: A case report.

ABSTRACT

Congenital pulmonary airway malformation is a rare congenital lung lesion. This report documents the successful application of thoracoscopic segmentectomy in a 1-year-old boy prenatally diagnosed with congenital pulmonary airway malformation. Preoperative imaging studies revealed a microcystic lesion with a region of consolidation in the middle area of the right lung. Elective thoracoscopic resection was performed when the patient was aged 1 year and 4 months. Intraoperatively, the superior segment of the right lower lobe was partially separated from the normal lower lobe by a superior accessory fissure. A solid mass, fused with this segment, shared the visceral pleura. Thoracoscopic segmentectomy was successfully performed, and the patient had an uneventful postoperative course. Histological examination revealed congenital pulmonary airway malformation stocker type 2. Thoracoscopic segmentectomy is a viable surgical option that preserves the normal lung parenchyma in pediatric patients with congenital pulmonary airway malformation.
