摘要
本文对70例脑动静脉畸形(AVM)进行回顾性研究,探讨脑 AVM 大小及引流静脉数与出血危险性的相关关系。全组男51例,女19例。年龄5~55岁。临床表现分为出血及非出血症状两大类。全例中,徽型或小型脑 AVM16例,中型30例,大型24例;引流静脉1支者37例,2支者11例,3支或3支以上者22例。结果提示:引流静脉数及脑 AVM 大小与出血危险性呈反相关关系。在制定脑AVM 治疗方案时,应考虑到脑 AVM 大小及其引流静脉数。
A retrospective study of 70 cerebral arteriovenousmalformations(AVMs)has been made to determinethe correlation between the number of efferent veinsand size of AVMs as related to haemorrhagic risks.There Were 51 males and 19 females.Patient agesranged from 5 to 55 years.The clinical manifestationswere divided into haemorrhagic and non-haemorrhagicgroups.There were 16 small AVM,30 mediumAVMs and 24 large AVMs in our series.37 of all thecases have only one efferent veins,11 have two and 22have multiple efferent veins.Statistical analysisdemonstrate that those AVMs with only one drainingvein have a high risk of bleeding(89.2%).As thenumber of drainage vein increased,bleeding risk de-creasing,becoming very low in AVMs with multipledrainage veins(4.5%).In another hand small andmedium AVMs usually have one drainage vein,thuscarrying a high risk of haemorrhage.As their size in-creased and efferent veins also established the possibil-ity of haemorrhage become less gradually.In makingtreatment scheme,the size and drainage veins ofAVMs should be taken into consideration.
