術前3D-CTにより中葉肺静脈の破格を把握し安全に胸腔鏡下右下葉切除を施行しえた1例

Thoracoscopic Right Lower Lobectomy Safely Performed after the Identification of Anomalous Middle Pulmonary Vein by Preoperative Three-dimensional Computed Tomography Angiography：Report of a Case

はじめに　術前の3D-CTでV4＋5とV6の共通幹を形成するまれな肺静脈破格を有する右下葉肺癌に対して，胸腔鏡下右下葉切除を施行した1例を経験したので報告する．

A complete thoracoscopic right lower lobectomy was successfully performed for a 74-year-old woman with an anomalous right middle lobe pulmonary vein, forming a common trunk of V4＋5 and V6. Preoperative three-dimensional computed tomography was useful to identify the vascular anomaly and contributed to perform safe surgery under the thoracoscopy.
