【摘要】 目的总结分析脑动静脉畸形(AVM)的临床特点及其显微外科治疗效果。方法回顾性分析103例显微手术治疗的脑AVM患者的临床资料,评估指标包括年龄,性别,AVM的部位、大小、供血动脉、引流静脉,是否伴有出血及显微手术治疗的效果。结果本组脑AVM患者平均年龄33．1岁；男：女比例为1．4：1；103例中伴脑出血的高达87例(84．5%)；AVM位于半球浅表功能区59例(57．3%)；小型AVM占47例(45．6%)；69例(67．0%)AVM有2根以上的供血动脉；单根引流静脉者占41例(39．8%)；显微手术疗效优69例,良14例,差10例,死亡10例。结论脑AVM好发于青壮年；男略多于女：多伴出血；多发生于半球浅表的功能区,其次是脑深部功能区；大小以微型到中型占大多数,巨大型少见：大部分AVM有多根供血动脉,少数有多根引流静脉；显微外科手术治疗脑AVM疗效优良、为大多数脑AVM患者的治疗首选。更多还原

【Abstract】 Objective To summarize and analyze the clinical characteristic and curative effect of 103 cerebral arteriovenous malformations(AVM).Methods The clinical characteristics of 103 AVM patients who had undergone microsurgery were retrospectively analyzed to evaluate the indexes including age,gender and curative effect,the location,size,feeding artery,drainage vein of AVM and combined hemorrhage.Results The average age of the patients with AVM was 33.1 years old,the ratio of male: female was 1.4:1.Among the 103 patients,87 patients(84.5%)had complication of cerebral hemorrhage.59 AVMs(57.3%)were located at hemispheric superficial domain,with a size of 2～4 cm in 47 cases(45.6%). 89 cases(67%)had hemorrhage in more than 2 arteries and 41(39.8%)had only single vein for drainage. The curative effect was excellent in 69 patients,good in 14 patients,bad in 10 patients and 10 patients were dead.Conclusion Cerebral AVM more likely occur in youth,usually combined with hemorrhage.The lesion is usually located at hemispheric superficial domain,with small size in most patients.Most AVMs have several feeding arteries and few AVMs have more than 2 drainage veins.Microsurgery,as the prime choice for most AVM patients,brings with the curative effect usually.更多还原
