JAMA:未破裂的脑动静脉畸形保守治疗或介入治疗后的转归

2014-04-25 刘素梅 译 中国医学论坛报

对于未破裂的脑动静脉畸形(bAVMs),由于缺乏长期的比较数据,保守治疗是否优于介入治疗尚不清楚。来自英国爱丁堡市爱丁堡大学临床脑科学中心临床神经分部的鲁斯塔姆·阿勒沙希·萨洛曼等博士考察比较了bAVMs保守治疗与介入治疗的长期转归。 设计、场所和参与者 对204名年龄≥16岁的居民进行了基于人群的起始队列研究,他们均于1999-2003年或2006-2010年期间首次被确诊为未破裂的bAVMs

对于未破裂的脑动静脉畸形(bAVMs),由于缺乏长期的比较数据,保守治疗是否优于介入治疗尚不清楚。来自英国爱丁堡市爱丁堡大学临床脑科学中心临床神经分部的鲁斯塔姆·阿勒沙希·萨洛曼等博士考察比较了bAVMs保守治疗与介入治疗的长期转归。

设计、场所和参与者 对204名年龄≥16岁的居民进行了基于人群的起始队列研究,他们均于1999-2003年或2006-2010年期间首次被确诊为未破裂的bAVMs,且之后接受了12年的前瞻性随访。

治疗 保守治疗(无介入)对比介入治疗[任何血管内栓塞(疗法)、神经外科切除术或立体定位放射外科手术,单用或联合应用]。

主要转归与检测指标 为比较主要转归[任何原因引起的死亡或持续病残率,牛津残障量表(OHS)评分≥2、持续≥2年(0=无症状,6=死亡]和次要转归(非致死性症状性卒中或bAVM、相关动脉瘤或介入治疗引起的死亡)的发生率,(研究人员)进行了考克斯(Cox)回归分析,如果风险成比例,则对预后因素和基线不平衡进行多变量校正。

结果 在204例患者中,103例接受了介入治疗。与接受保守治疗者相比,接受介入治疗者较年轻,更可能有癫痫表现,有大bAVMs的可能性较小。中位随访6.9年(随访完成率为94%),随访的前4年内,保守治疗组患者进展至主要转归的发生率较低(36对39次事件,9.5对9.8次/100人-年,校正风险比为0.59,95%可信区间为0.35~0.99),但随后两组的发生率相似。在12年的随访期内,保守治疗组患者的次要转归发生率较低(14对38次事件,1.6对3.3次/100人-年,校正风险比为0.37,95%可信区间为0.19~0.72)。

结论 与相关性在年龄≥16岁、确诊有未破裂的bAVMs患者中,与接受介入治疗相比,接受保守治疗与治疗后12年内的临床转归较好相关。需要进行更长时间的随访研究,以了解这种相关性是否能够持续。

Lancet:未破裂的脑动静脉畸形仅药物治疗就足够了吗?(ARUBA试验)

背景:未破裂脑动静脉畸形进行预防性根治的临床获益仍存在争议。ARUBA是一项随机试验,旨在比较这些患者接受单一药物治疗或药物联合介入治疗,对死亡和症状性脑卒中风险的影响。 方法:在九个国家共39个临床中心招募的未破裂脑动静脉畸形成年患者(18岁以上),被随机分配至药物联合介入治疗组(介入治疗包括神经外科手术、血管栓塞术或立体定向放射治疗,可单用或联用)、药物治疗组(如果有需要,则针对神经

大型脑动静脉畸形的栓塞策略和技巧

由于缺乏理想的栓塞材料,血管内治疗脑动静脉畸形(AVM)的治愈率一直较低。氰基丙烯酸正丁酯(NBCA)有粘管的危险性,不能长时间注射,因此对于大型脑AVM栓塞疗效很不理想。 近年来,新型液态栓塞剂Onyx应用于临床,使脑AVM的栓塞疗效明显提高。Onyx不易与微导管粘连,可以长时间缓慢注射,且弥散性和可控性较好。使用Onyx血管内栓塞治疗目前巳是国内外治疗大型脑AVMW或缺的重雖施之一。
