摘　　要：目的总结Ｘ－刀治疗脑动静脉畸形的效果。方法作者应用Ｘ－刀技术治疗脑动静脉畸形（ＡＶＭ）１７例。其中，位于幕上者１５例，幕下者２例。１７例患者均为单次照射，边缘剂量１５～３０Ｇｙ。结果２年内ＡＶＭ完全消失者１３例，部分消失者３例，无变化者１例。治疗后出现放射性脑水肿２例。经保守治疗患者症状改善。结论Ｘ－刀治疗脑血管畸形有其独特的作用。Objective To summarize the effectiveness of radiosurgery for cerebral arteriovenous malformations(AVMs). Method We treated with linear accelerator radiosurgery 17 patients harboring AVMs in the brain.15 AVMs were located supratentorially and others infratentorially.All the patients were treated with singal fraction.The doses at AVM margin were 15 to 30 Gy. Result AVMs disapeared in 13 of the 17 patients, reduced in 3 and unchanged in only 1 at 2 year follow up.Vasogenic edema observed in 2 patients,their neurologic deficits were all improved with steroid. Conclusion Linear accelerator radiosurgery is effective in dealing with cerebral AVMs. It provides with a new means of treatment for AVMs which can′t be effectively treated with microsurgery and embolization.
