Five patients exhibited an apparently communicating hydrocephalus -- type of disorder, with ventricular reflux on the cisternograms, lack of air-encephalographic parasagittal air-filling and clearly enlarged temporal horns. The group seemed heterogeneous, with regard to age distribution; possible etiological factors and duration of the hydrocephalic process. In all 5 patients increased intracranial/intrathecal pressure was observed: in 2 patients, only with intrathecal measurement in the lumbar area, but in the remaining 3 patients with epidural/ventricular fluid pressure monitoring. Continuously increased pressure extending over 1 or more days was observed in these patients. This pressure increase may seem different from the episodic pressure increase previously reported in normal-pressure hydrocephalus. These patients seem to be cases of so-called normal-pressure hydrocephalus according to the commonly accepted criteria. It is therefore suggested that the term normal-pressure hydrocephalus should be abandoned, and replaced by, e.g., low-pressure hydrocephalus, malresorptive or malabsorptive hydrocephalus.
5例患者表现为明显的交通性脑积水——一种疾病类型，脑池造影显示脑室反流，脑气造影矢状旁气腔未充盈，颞角明显扩大。该组患者在年龄分布、可能的病因以及脑积水病程方面似乎具有异质性。所有5例患者均观察到颅内/鞘内压升高：2例患者仅通过腰椎区域鞘内测量发现，但其余3例患者进行了硬膜外/脑室液压力监测。这些患者观察到压力持续升高超过1天或更长时间。这种压力升高可能与先前报道的正常压力脑积水的间歇性压力升高有所不同。根据普遍接受的标准，这些患者似乎是所谓正常压力脑积水的病例。因此，建议放弃“正常压力脑积水”这一术语，并用例如“低压脑积水”“吸收不良性脑积水”来替代。
