This paper reviews the mechanics of shunts currently used to treat hydrocephalus and contrasts these devices with the normal mechanism of CSF circulation. These differences are examined with reference to the biomechanical testing performed in hydrocephalus children. These studies show that in most untreated hydrocephalics, enhanced volume storage accompanies a partial absorptive defect. After treatment, volume storage changes in most children but persists in a minority. Using these tests, it is possible to describe the requirements for successful shunting of hydrocephalic children at all stages of the process. This discussion elaborates the theoretical requirements for revising current shunt design.
本文回顾了目前用于治疗脑积水的分流装置的力学原理，并将这些装置与脑脊液正常循环机制进行了对比。参照对脑积水患儿进行的生物力学测试，对这些差异进行了研究。这些研究表明，在大多数未经治疗的脑积水患者中，容量储存增加伴随着部分吸收缺陷。治疗后，大多数患儿的容量储存情况发生变化，但仍有少数患儿持续存在该情况。通过这些测试，可以描述脑积水患儿在整个治疗过程中成功分流的要求。本讨论详细阐述了改进当前分流装置设计的理论要求。
