作者报道Mayo医院用γ刀治疗5例11个(2例复发,2例残存,7例新诊断)脑膜血管外皮细胞瘤。每个患者曾至少1次开颅(1～6个肿瘤作1～3次手术)切除病变,继用放射外科治疗(3例)或在颅内不同位置切除肿瘤(2例)。3例放射外科前用分割外照射50～53Gy。此次放射外科是置患者于立体定向架内(LeksellG型),局麻下作立体定向CT扫描以确定肿瘤边缘与剂量计划等中心坐标,1例后颅窝多病灶者为更清楚显示肿瘤与周围结构还用了立体MR显象。最后的剂量计划是经Micro Vax计算机完成,后来用一种新的、
The authors reported that Mayo Hospital treated 5 patients with gamma knife in 11 patients (2 recurrent, 2 survived, and 7 newly diagnosed) with meningeal vascular hemangiomas. Each patient had at least one craniotomy (1 to 6 tumors for 1 to 3 surgeries) at least one time, followed by radiosurgery (3) or resection of the tumor at various locations in the skull (2). Three cases before radiosurgery with external irradiation 50 ~ 53Gy. The radiosurgery is to set the patient in the stereotactic frame (LeksellG type), under local anesthesia for stereotactic CT scan to determine the tumor margin and dose planning center coordinates, a case of multiple posterior fossa lesions in order to more clearly show the tumor and The surrounding structure also used stereoscopic MR imaging. The final dose plan was completed by a Micro Vax computer and later replaced by a new,
