摘要
目的探讨低颅内压脑积水（LPH）的临床特征、发病机制和诊治方法O方法2007年1月至2011年10月收治LPH患者7例，均采用可调压分流管行脑室一腹腔分流术㈧Ps）治疗，其中1例内引流前行脑室外引流术采取负压引流确诊，余6例均为正常压力脑积水内引流后随访中根据症状反复调压后确诊。结果本组7例VPS后随访3。33个月，除1例高龄患者（73岁）术后1年有轻度头昏、反应迟钝、智力下降外，余6例症状明显缓解，扩大脑室显著回缩。结论LPH临床少见，发病隐蔽，临床表现与正常颅压脑积水相类似；头部CT及MRI可表现为脑室扩大，部分甚至室周明显水肿；可调压管行VPS是治疗LPH的有效方法。
Objective To explore the clinical symptoms, pathogenesis, diagnosis and treatment of low intracranial pressure hydrocephalus （LPH）. Methods The ventrieulo-peritoneal shunt （VPS） with pressure- adjustable valves was performed in 7 patients with hydrocephalus. The diagnosis of LPH in 1 patient was definitely made by the suction extraventrieular drainage before VPS. LPH developed during the following-up during which the patients＇ symptoms were not improved untile the drainage under the negative pressure in 6 patients with normal pressure hydrocephalus. Results The following-up from 3 to 33 months after VPS showed that the clinical symptoms were improved and the enlarged ventricles significantly retracted in 6 patients, and the action was slow and intelligence declined possibly due to encephalatrophy 1 year after VPS in 1 patient aged 73 years. Conclusions LPH is uncommon and occultly comes on. LPH is similar to normal pressure hydrocephalus in the clinical manifestation. CT and MRI show that there are ventriculomegaly in all the patients with LPH and periventrieular edema in some patients with LPH. VPS with pressure-adjustable valve is an effective method to treat LPH. The perfect threshold value of pressure adjustable valves, which is suitable for the individual may be ~ot bv more than once adiustment and long-term observation of the curative effect.
