The so called slit-ventricle syndrome appears as a potential complication of the CSF derivations, whatever their types. It consists of repetitive episodes of elevated intracranial pressure, associated with collapsed ventricles as demonstrated by CT scan. Clinical symptoms happen after several months or years during which the derivation worked well, and then get more and more frequent. Between the episodes, the only statement one can do is the slow re-filling of the pump after it has been depressed with finger. The valveless lumbo-peritoneal derivations, and the ventriculo-atrial or ventriculo-peritoneal derivations using a low-pressure valve, are most often found in patients with the slit-ventricle syndrome. This suggests that overdrainage of the CSF is likely to be the main cause of this syndrome. Possible managements comprise: changing the valve, for an other one with a higher opening pressure,--adding to the derivation an antisyphon device, and making a subtemporal decompression.
所谓的裂隙脑室综合征似乎是脑脊液引流的一种潜在并发症，无论其类型如何。它表现为颅内压反复升高，并伴有CT扫描显示的脑室塌陷。临床症状在引流装置正常工作数月或数年后出现，且发作越来越频繁。在发作间隙，唯一能观察到的情况是用手指按压泵后，泵会缓慢重新充盈。无阀腰大池 - 腹腔分流术，以及使用低压阀的脑室 - 心房或脑室 - 腹腔分流术，最常出现在患有裂隙脑室综合征的患者中。这表明脑脊液过度引流可能是该综合征的主要原因。可能的处理方法包括：更换瓣膜，换成开启压力更高的另一种瓣膜；在引流装置上添加抗虹吸装置；以及进行颞下减压术。
