Stroke:动脉瘤性蛛网膜下腔出血患者通过腰椎导管进行脑脊液过滤的疗效

2019-08-01 xing.T MedSci原创

由此可见,PILLAR治疗动脉瘤性蛛网膜下腔出血的初步尝试具有安全性和可行性,其证明了安全过滤脑脊液和清除血液和血液副产物的潜能。

通过脊柱导管进行体外蛛网膜下腔出血过滤(PILLAR)研究是动脉瘤性蛛网膜下腔出血患者进行脑脊液(CSF)过滤的首次人体试验。近日,心血管疾病领域权威杂志Stroke上发表了一篇研究文章,该研究旨在评估一种新型过滤系统对患者动脉瘤破裂后迅速从脑脊液中清除血液血液分解产物的安全性和可行性。

动脉瘤性蛛网膜下腔出血的患者在动脉瘤固定后放置双腔腰椎、鞘内导管,并接受长达24小时的CSF过滤(神经再灌注治疗)。导管从腰部池吸入受血液污染的CSF,并将过滤后的CSF返回到胸蛛网膜下腔。在进行2小时后进行神经检查,收集CSF样品用于细胞计数,总蛋白质和革兰氏染色检查。在基线和过滤后获得计算机断层扫描结果。在2周和30天进行临床随访。

13名患者放置了导管(平均时间为发作后24:13小时)。该系统在过滤的15:07小时(5:32-24:00小时)内过滤了632.0mL(180.6-1447.6mL)CSF。平均初始CSF红细胞计数为2.78×10 5个细胞/μL,过滤后降低至1.17×10 5个细胞/μL(减少52.9%),总蛋白质减少71%。对基线和滤过后计算机断层扫描的独立分析发现脑池血液显著减少,平均Hijdra评分降低46.5%。研究人员报告了三种轻微的可预期的不良事件。 

由此可见,PILLAR治疗动脉瘤性蛛网膜下腔出血的初步尝试具有安全性和可行性,其证明了安全过滤脑脊液和清除血液和血液副产物的潜能。
