CT-guided stereotaxic systemによるOmmaya reservoir埋込み術の有用性

CT-Guided Stereotaxic Implantation of Ommaya Reservoir for Cystic Brain Tumor

I．はじめに

　脳腫瘍内のcystにOmmaya reservoirを埋込む際，目標点の決定，穿刺ルートの選択，tubeの長さの決定などは，従来のfree handによる操作では不正確であったが，われわれはこれらをCTで確認しながら定位的に行っており，有用であると考えられたので報告する．

We report the use of CT-guided stereotaxic system to implant Ommaya reservoir in 26 patients with cystic brain tumors consisting of 16 gliomas, 3 craniopharyn-giomas, 3 metastatic brain tumors and 5 other and un-known pathologies, on the way of their biopsy. The en-tire procedure was carried out in the CT room using Leksell's CT stereotaxic system.
