老年患者脑动静脉畸形的临床特点及治疗策略

Clinical Features and Treatment Strategy of Brain Arteriovenous Malformations in Elderly Patients

目的探讨老年患者脑动静脉畸形的临床特点及治疗策略。方法对首都医科大学附属北京天坛医院自1997年3月至2008年9月收治的老年脑动静脉畸形患者25例进行回顾性分析,总结患者的临床症状、治疗策略及其预后。结果患者首发症状为颅内出血者17例(68.0%),非出血引发的神经功能缺失者4例(16%),顽固性头痛、头晕者4例(16%)。25例患者中有4例行多种治疗方案,累计治疗共30次。选择保守治疗者7例,其中有4例(57.1%)患者在保守治疗期间发生出血或再出血;选择进行放射治疗者共7例,其中3例(42.9%)随访过程中出现出血,2例患者出现神经功能缺失;选择进行介入栓塞治疗者共5例,2例为完全栓塞,1例死于术后脑梗死;另外3例部分栓塞;选择进行手术治疗者共11例,其中急诊手术3例,择期手术8例,11例患者手术患者中死亡2例(18.2%),其余9例患者中,2例急性出血患者术后分别出现不全混合性失语和癫痫发作,7例择期手术患者未出现与手术相关的神经功能缺失,术前症状得到不同程度改善。结论老年患者脑动静脉血管畸形多见于男性,有较高出血率。显微神经外科手术切除是治疗老年脑动静脉畸形安全和有效的方法,高龄不是手术切除脑动脉畸形的禁忌证。

Objective To analyze clinical features and treatment strategy of brain arteriovenous malformations(AVMs) in elderly patients(age≥60 y).Methods A retrospective survey of 25 cases of brain AVMs in elderly patients diagnosed from March 1997 to September 2008 in Beijing Tiantan Hospital was undertaken.The clinical features,treatment and outcomes were analyzed along with a systematic review of literature.The median follow-up period was 50 months(4~120 months).Results In this series the median age of patients was...
