title: Video-assisted anatomic mediobasal segmentectomy of lung.
abstract: Although video-assisted thoracic surgery (VATS) is now widely accepted, pulmonary segmentectomy is rarely performed. We present a case series of patients undergoing this procedure. The first patient had multiple arteriovenous malformations of the right mediobasal segment and a leiomyoma in the bronchus of the mediobasal segment. The second patient had multiple pulmonary metastases from colon cancer, including one in the right mediobasal segment. The third patient had metastases in the right ventrobasal and mediobasal segments from a solitary fibrous tumor that originated in the contralateral diaphragm. In the first two patients, a solitary mediobasal segmentectomy was done. In the third patient, a combined ventrobasal and mediobasal bisegmentectomy was performed. There were no complications, and visualization was excellent. Because VATS provides such excellent exposure, mediobasal segmentectomy of the lung is feasible, even though this operation is not done as an open procedure.
