Video-assisted thoracoscopic right upper lobectomy in a patient with a displaced bronchus and vascular abnormalities.

Bronchial abnormalities are rare, and they are infrequently associated with pulmonary vascular abnormalities. It is important to identify such abnormal anatomical structures before lobectomy of the lung under thoracoscopy. There have been only three reports on video-assisted thoracoscopic lobectomy in patients with anomalous bronchi and vascular abnormalities to date. Here, we present a report of video-assisted thoracoscopic right upper lobectomy performed in a patient with bronchial and vascular abnormalities. Both preoperative imaging and intraoperative findings revealed a displaced anomalous B bronchus arising from the bronchus intermedius, as well as abnormal distribution of the aberrant vein V draining into vein V . It is critical to understand the precise anatomical structures preoperatively to perform video-assisted thoracoscopic pulmonary lobectomy safely.
