Description

<p>Although aberrant fissure of the lung is sometimes noted during pulmonary resection, most cases show a partial or incomplete division. We encountered two cases of pulmonary segmentectomy for lung cancer with a distinct aberrant fissure between the left upper and lingular divisions. In case 1, a 57-year-old man with lung cancer in the left S1+2 underwent thoracoscopic upper segmentectomy. There was a distinct aberrant fissure between the left upper and lingular divisions and the pulmonary artery ran anterior to the anomalous upper bronchus with independent upper segmental branching. In case 2, an 80-year-old woman with lung cancer in the left lingular segment underwent thoracoscopic lingual segmentectomy. There was a distinct aberrant fissure between the left upper and lingular divisions with no aberrant ramifications of the bronchus or vessels except for the common pulmonary vein. Postoperative courses of the two cases were uneventful, and there has been no recurrence of lung cancer to date. Herein, we report these cases with a review of the literature.</p>
