Owing to all the difficulties involved in selecting patients with normal pressure hydrocephalus for shunt-operation, a cerebrospinal fluid-tap-test (CSF-TT) is introduced. Psychometric and motor capacities of the patients are measured before and after lumbar puncture and removal of 40-50 ml CSF. Patients fulfilling criteria for normal pressure hydrocephalus were compared to patients with dementia and atrophy shown by computed tomography. Normal pressure hydrocephalus patients showed temporary improvement after lumbar puncture. The extent of the temporary improvement appeared to be well correlated with the improvement after shunt operation. Accordingly, the CSF-TT seems to be of value when selecting those patients who will probably benefit from a shunt operation.
由于选择正常压力脑积水患者进行分流手术存在诸多困难,因此引入了脑脊液穿刺试验(CSF-TT)。在腰椎穿刺并抽取40 - 50毫升脑脊液前后,测量患者的心理测量和运动能力。将符合正常压力脑积水标准的患者与计算机断层扫描显示有痴呆和萎缩的患者进行比较。正常压力脑积水患者在腰椎穿刺后显示出暂时改善。这种暂时改善的程度似乎与分流手术后的改善情况密切相关。因此,脑脊液穿刺试验在选择可能从分流手术中获益的患者时似乎具有价值。
