The intrathecal infusion test leads to a more accurate diagnosis of communicating hydrocephalus, and is useful in identifying those patients with insufficient cerebrospinal fluid (CSF) absorption who are most likely to improve after a shunt operation. Furthermore, shunt function can be evaluated by assessing the CSF absorption of shunt-operated patients in the same way. Some patients do not improve after surgery because of irreversible or shunt-independent neurological and radiological signs, while the postoperative infusion test demonstrates a normal shunt function. The clinical condition and neuroradiological picture of such patients cannot be improved by shunt revision if the implanted shunt already allows a normal CSF outflow. By means of infusion tests the number of patients who need a further operation can be reduced, with a consequent drop in shunt infections, a very welcome aspect especially in pediatric neurosurgery. In our department 298 infusion tests were carried out over a seven-year period, and a decrease in shunt revisions and infections could be observed.
鞘内注入试验能更准确地诊断交通性脑积水，有助于识别那些脑脊液（CSF）吸收不足、分流手术后最有可能改善的患者。此外，通过同样的方式评估接受分流手术患者的脑脊液吸收情况，可对分流功能进行评估。一些患者术后没有改善是由于不可逆或与分流无关的神经和放射学表现，而术后注入试验显示分流功能正常。如果植入的分流装置已能使脑脊液正常流出，那么对此类患者进行分流装置修复并不能改善其临床状况和神经放射学表现。通过注入试验，可以减少需要进一步手术的患者数量，从而降低分流感染的发生率，这在小儿神经外科尤其值得欢迎。在我们科室，七年间共进行了298次注入试验，分流装置修复和感染情况有所减少。
