肺静脈走行異常を伴った肺癌切除の1例

Surgical Case of Lung Cancer with Anomalous Right Pulmonary Vein；Report of a Case

はじめに　肺癌手術を遂行するうえで肺血管の分岐・走行異常を術前に把握することは大変重要である．われわれは術前に右肺静脈（V8）の走行異常を把握し，安全に手術を行うことができたので報告する．

We report a case of an anomalous pulmonary vein with right V8. A 67-year-old man was found to have an abnormal shadow on chest X-ray film. He had a diagnosis of clinical stage IB lung adenocarcinoma. Preoperative three-dimensional computed tomographic angiography （3D-CT angiography） showed middle lobe pulmonary vein directly flow into the left atrium and the right V8 flow into the middle lobe pulmonary vein. Based on these findings, right lower lobectomy was safely and successfully performed. A complete understanding of the anatomic features of the pulmonary vascular branches prior to surgery is essential for safe and accurate pulmonary resection.
