部分肺静脈還流異常症を伴う右上葉切除の1例

Right Upper Lobectomy for Lung Cancer with Partial Anomalous Pulmonary Venous Connection；Report of a Case

はじめに　肺静脈還流異常は肺静脈系が左房に流入せずに体静脈系に流入する先天奇形で，総肺静脈還流異常（TAPVC）と部分肺静脈還流異常（PAPVC）に分類される1）．われわれは，術前CTでPAPVCを認めた患者の右上葉肺癌に対して右上葉切除を行った1手術例を報告する．

A 75-year-old woman was pointed out a mass shadow in the right upper lobe by chest computed tomography （CT） 3 month ago. Bronchoscopic examination revealed adenocarcinoma, and right upper lobectomy was performed. Preoperatively, it was revealed that V1＋2 returned to the superior vena cava while V3 returned to the normal position. Postoperative course was uneventful and there has been no recurrence 6 months post-surgery.
