BACKGROUND AND OBJECTIVE
The Medtronic PS Medical Strata valve has pressure flow characteristics that are noninvasively adjusted with a magnetic tool. The objective of this study was to examine its efficacy during our initial experience with it in shunt-dependent children.
MATERIALS AND METHODS
A retrospective review of 53 children with a median age of 2.0 years who had 61 Strata valves implanted.
CONCLUSION
The Strata valve is efficacious in the treatment of shunt-dependant hydrocephalus in children. The 1-year shunt survival rate of 67.2% is comparable to that previously reported from a multicenter trial. Of the 30 therapeutically aimed adjustments during the study period, 16 (53.3%) resulted in improvement in abnormal signs or symptoms. Our data indicate that adjustments can be used to treat signs or symptoms of cerebrospinal fluid overdrainage or underdrainage, which may obviate the need for additional surgery.
背景与目的
美敦力PS Medical Strata分流阀具有压力流量特性，可通过磁性工具进行无创调节。本研究的目的是在我们对依赖分流的儿童首次使用该分流阀的过程中，检验其疗效。
材料与方法
回顾性分析53例年龄中位数为2.0岁、植入了61个Strata分流阀的儿童。
结论
Strata分流阀在治疗儿童依赖分流的脑积水方面有效。1年分流存活率为67.2%，与之前多中心试验报告的结果相当。在研究期间进行的30次有治疗目的的调节中，16次（53.3%）使异常体征或症状得到改善。我们的数据表明，调节可用于治疗脑脊液引流过多或过少的体征或症状，这可能无需额外手术。
