作者报告了1984年11月～1992年8月间用直线加速器放射外科治疗180例脑动静脉畸形(AVM)病人,其中男性85例,女性95例,平均年龄32.2岁。临床表现:脑出血149例,癫痫23例,神经衰弱6例,突眼1例,放射治疗前,25例曾1次或多次接受手术,但未成功。9例不完全栓塞,72例病灶位于深部或后颅窝(基底节36例,脑干15例,及胼胝体11例,小脑10例)。108例位于半球皮质或皮质下(颞叶45例,枕叶22例。顶叶33例,额叶8例)。病变位于左侧86例,右侧83例,累及中线结构12例。病变直径4～40mm,(平均16.1mm),靶中心单次剂量18.7～40GY,(平均28.
The authors reported 180 patients with cerebral arteriovenous malformation (AVM) who underwent radiosurgery with a linear accelerator between November 1984 and August 1992, 85 were males and 95 were females with a mean age of 32.2 years. Clinical manifestations: Cerebral hemorrhage in 149 cases, 23 cases of epilepsy, neurasthenia in 6 cases, exophthalmos in 1 case, before radiation therapy, 25 cases had one or more times underwent surgery, but failed. Nine cases were incompletely embolized, and 72 lesions were located in deep or posterior fossa (basal ganglia 36, brain stem 15, and corpus callosum 11, cerebellum 10). 108 cases were located in the hemisphere cortex or under the cortex (45 cases of temporal lobe, occipital lobe 22 cases, parietal lobe 33 cases, frontal lobe 8 cases). The lesions were located on the left side in 86 cases and on the right side in 83 cases, involving the midline structure in 12 cases. Lesions diameter 4 ~ 40mm, (average 16.1mm), the target single-dose center 18.7 ~ 40GY, (average 28.
