To report the results of the use of the stereotactic techniques in the management of intra cranial lesions.
Between july 1994 and march 1998, we carried out 117 stereotactic procedures of whom only 100 cases were analyzed. All the procedures were achieved after a CT scan. Patients were separated in two groups: (A) stereotactic biopsy (91 patients), (B) surgery with laser guidance (9 patients). The mean age in group A was 38 years (2-75 years) versus 27 years (11-66 years) in group B. The sex-ratio was 1.3.
In the group A, the correct pathological diagnosis was obtained in 91.2% of cases. Glial tumors was the frequent histopathological variety of tumor (67.47%). Only one patient was operated after biopsy for a bilateral meningioma of the anterior 1/3 of the falx. There was only one death (1.09%) and 3.29% of transitory complications. In the group B, all patients were operated with laser guidance. Thirty seven per cent of patients underwent radiotherapy after the stereotactic biopsy or surgery.
Stereotactic biopsy is a reliable method for the histopathological diagnosis of deep-seated brain lesions. Surgery with laser guidance is a useful alternative for the management of small deep-seated lesions or lesions located in functional areas.
报告立体定向技术在颅内病变治疗中的应用结果。
1994年7月至1998年3月，我们共进行了117例立体定向手术，仅对其中100例进行分析。所有手术均在CT扫描后完成。患者分为两组：（A）立体定向活检（91例），（B）激光引导手术（9例）。A组平均年龄38岁（2 - 75岁），B组平均年龄27岁（11 - 66岁）。性别比为1.3。
A组中，91.2%的病例获得了正确的病理诊断。胶质肿瘤是最常见的肿瘤组织病理学类型（67.47%）。活检后仅1例患者因双侧大脑镰前1/3脑膜瘤接受手术。仅1例死亡（1.09%），短暂并发症发生率为3.29%。B组所有患者均接受激光引导手术。37%的患者在立体定向活检或手术后接受了放疗。
立体定向活检是深部脑病变组织病理学诊断的可靠方法。激光引导手术是治疗小的深部病变或位于功能区病变的有用替代方法。
