Stroke:未破裂脑动静脉畸形!

2017-11-07 xing.T MedSci原创

在uBAVM试验中,单独进行Onyx栓塞或联合立体定向放射治疗取得了较高的闭塞率。发病率仍然是一个挑战,即使它似乎比ARUBA试验中要低。

根据未破裂脑动静脉畸形随机试验(ARUBA试验)的证据,神经血管专家不得不重新考虑未破裂脑动静脉畸形(uBAVMs)的专科治疗。近日,卒中领域权威杂志Stroke上发表了一篇研究文章,研究人员的目的是确定采用乙烯-乙烯醇(ONYX)通过栓塞治疗uBAVM的疗效。

uBAVM试验的患者满足ARUBA的入选标准,并采用Onyx栓塞治疗的患者被分配到该回顾性研究。该研究的主要结局为改良的Rankin量表评分。次要结局为由于uBAVM或干预以及uBAVM闭塞所致的卒中或死亡。

该研究纳入了六十一例(平均年龄为38岁)的患者。中位观察期为60个月。患者接受单纯栓塞治疗(41%)、栓塞和放射治疗(57.4%)或栓塞和切除(1.6%)治疗。在完成治疗的57例患者中有44例达到闭塞(77.2%)。四十七例患者(77.1%)在观察结束后没有发生临床功能障碍(改良Rankin量表评分< 2)。十二例患者(19.7%)由于uBAVM或干预发生了卒中或死亡的结局。治疗相关的死亡率为6.6%(4例)。

在uBAVM试验中,单独进行Onyx栓塞或联合立体定向放射治疗取得了较高的闭塞率。发病率仍然是一个挑战,即使它似乎比ARUBA试验中要低。
