内照射是脑瘤局部治疗的一种有发展前途的方法.在用立体定向术置入放射物质时会遇到治疗剂量达到后需要除去剩余放射源问题,以免周围正常脑组织受损害.作者用装有可除去放射源的导管解决了此问题,并能准确进入肿瘤.本文介绍用载有~125碘的导管植入法治疗20例脑瘤病人.
Internal irradiation is a promising method of local treatment of brain tumors.When stereotactic placement of radioactive material will encounter the treatment dose to reach the need to remove the remaining radioactive sources, so as to avoid the surrounding normal brain tissue damage. Catheterization with a radioactive source solves this problem and allows accurate access to the tumor.This article describes the treatment of 20 patients with brain tumors using catheterization with ~125 iodine.
