CT立体定向脑组织活检90例分析

CT-Guided Stereotactic Brain Biopsy in 90 Cases Analysis

目的：采用CT引导立体定向术对脑内病变进行活检，为诊断与治疗及其预后的评估提供组织学依据。材料与方法：使用CJF-I型脑立体定向系统和SOMATOMCR或SOMATOMPlus-4CT机，对90例脑肿瘤和非肿瘤性病变实施立体定向脑活检。结果：82例获得明确的病理诊断，占91．1％，无严重手术并发症和死亡。结论：CT立体定向脑活检术是安全的，具有很高的确诊价值。作者就手术操作技巧进行了详细探讨。

Purpose: To provide the histologic specimen for the disgnosis and therapeutic and prognosis of brain disease with stereotactic biopsies. Materials and Methods: 90 cases that 50 cases had brain neoplasm and 40 cases non-neoplasm were performed CT -guided stereotactic biopsy using CJF - I brain stereotactic system and SOMATOM CR as well as SOMATOM Plus- 4 CT scanners. Results:A mong them,the accurate pathological diagonsis was obtained in 82 cases (91.1% ) and not diagnosis result in eight. There were no mortality and serious complications. Conclusio.: Authers suggest that this method is safe and precise, can provide important evidence for the diagnosis, treatment and prognosis of intracerebral disease. The operative technique are discussed in detail in this paper.
