为了评价用立体定向放射手术治疗海绵窦脑膜瘤的效果,作者回顾了1988年5月到1992年1月间用201个钴_(60)源的r-刀采用立体定向放射手术治疗的34例病人(27例女性,7例男性)。其中28例(82%)以前为切除肿瘤曾行1～5次开颅手术(人均1.8次),均经病理学证实为脑膜瘤。进行放射手术治疗的条件是:1)肿瘤平均直径<35mm;2)肿瘤距视神经或神经管足够远(通常>4mm);3)由于惧怕手术危险而拒绝接受显微外科手术。病人经高分辨CT 增强扫描或MRI 进行肿瘤定位后,用Lek-
To evaluate the efficacy of stereotactic radiosurgery in the treatment of cavernous sinus meningiomas, the authors reviewed 34 patients treated with stereotactic radiosurgery with 201 cobalt-60 source r-knives from May 1988 to January 1992 Patient (27 women, 7 males). Among them, 28 (82%) had previously performed craniotomy (1-5 times) for resection of the tumor (1.8 per capita), all confirmed by pathology as meningioma. The conditions under which radiosurgery is performed are: 1) the average tumor diameter <35 mm; 2) the tumor is sufficiently far (usually> 4 mm) from the optic nerve or neural tube; and 3) the microsurgical treatment is rejected for fear of surgical risk. After high-resolution CT scan or MRI tumor localization, with Lek-
