Right Lower Lobe Superior Segmentectomy in a Patient With a Displaced Bronchus.

An 81-year-old woman with adenocarcinoma in the lower superior segment of the right lung underwent superior segmentectomy of the right lower lobe through a thoracotomy. Preoperatively, we detected an anomalous B10c bronchus branching from the right lower superior segment bronchus with multiplanar reconstruction computed tomography and virtual bronchoscopy. Intraoperatively, we stapled and cut the right lower superior segment bronchus at the level of the peripheral anomalous B10c bronchus under bronchoscopic visualization. Precise anatomic understanding is very important for segmentectomy, especially in patients with anomalous bronchi. Multiplanar reconstruction computed tomography and virtual bronchoscopy are useful for preoperative planning.
