作者对所在医院1987～1992年间经血管造影证实的313例AVM作了γ-刀治疗,其中有2个病人有2处病灶,故共计315个病灶。其中295(94％)例随访达24个月以上。作者分析了220例(占总数的70％)病人,其中203例在24个月或更长时间复查了血管造影,7例AVM经γ-刀治疗未消失而行手术切除,1例出现新的神经功能障碍而无影像学资料,9例死亡。另有30％的病人因γ-刀治疗后拒绝血管造影复查而排除在外,这些病人无一例出现新的神经功能障碍。48例 The author of the hospital from 1987 to 1992 confirmed by angiography of 313 cases of AVM γ-knife treatment, of which 2 patients have 2 lesions, so a total of 315 lesions. Of these, 295 (94%) were followed up for more than 24 months. The authors analyzed 220 patients (70% of the total), 203 of whom underwent angiography at 24 months or longer. Seven AVMs were surgically removed without gamma-knife treatment and one with new Nerve dysfunction without imaging data, 9 patients died. Another 30% of patients were excluded from the angiographic review after gamma-knife treatment and none of these patients developed new neurological dysfunction. 48 cases
