Abstract

We report one of the rare anatomical variations of the pulmonary vein wherein the left V2 drained into the inferior pulmonary vein. A 63-year-old man was referred to our hospital because of an abnormal shadow in the left lower lung field that was noted on chest X-ray. Computed tomography (CT) revealed a tumor in the left lower lobe. A biopsied tumor specimen was diagnosed as an adenocarcinoma, and thus, left lower lobectomy was performed. Preoperative three-dimensional CT revealed that an anomalous V2 of the left lung drained from the superior segment into the inferior pulmonary vein. This variation type was confirmed during thoracoscopic left lower lobectomy. We were able to perform left lower lobectomy with the preservation of the anomalous V2. The postoperative course was uneventful, and the patient was discharged on postoperative day 12. It is important to identify anatomical variations of the pulmonary vein and reliably preserve and process the affected area to prevent postoperative complications.
