作者报告从1980年10月至1990年5月间,在美国放射外科中心接受立体定向Bragg质子束照射治疗的68例脑AVM病例。该组患者或者由于AVM病灶的大小和/或部位的关系而认为手术危险性高,或者因患者拒绝手术,所以选择放疗。有63例患者(92.6％)获得了完整的临床和放射学随访检查。结果表明临床和放射学的远期效果与AVM病灶大小和$petzler—Martin分级有关。 资料和方法 本组男30例,女38例,年龄14～60岁,平均32.8岁。68例AVM中,28例(41.2％)病变位于顶叶双侧,15例(22％)位于左
The authors report 68 patients with brain AVM who underwent stereotactic Bragg proton beam irradiation at the U.S. Radiological Center between October 1980 and May 1990. This group of patients chose radiotherapy because of the high risk of surgery due to the size and / or location of the AVM lesion, or because the patient refused surgery. Sixty-three patients (92.6%) received complete clinical and radiological follow-up examinations. The results indicate that the long-term clinical and radiological effects are related to AVM lesion size and the petzler-Martin classification. Materials and Methods The group of 30 males and 38 females, aged 14 to 60 years, mean 32.8 years old. In 68 cases of AVM, 28 cases (41.2%) were located on both sides of the parietal lobe, 15 cases (22%) were located on the left
