目的 :研究原发性低颅内压综合征的临床及治疗。方法 :对近 3年收治的 6例原发性低颅内压综合征患者观察其临床表现、脑脊液压力及治疗效果。结果 :当患者起立位时出现头痛、呕吐及颈强直 ,卧位时症状消失 ,脑脊液压力均低于7cmH2 O。当临床症状缓解时脑脊液压力恢复正常。结论 :了解原发性低颅内压综合征的临床表现、脑脊液压力至关重要 ,有时易与颅内高压混淆 Objective: To study the clinical and treatment of primary hypocephalic pressure syndrome. Methods: The clinical manifestations, cerebrospinal fluid pressure and therapeutic effect of 6 patients with primary hypoccnical syndrome admitted in the past 3 years were observed. Results: Headache, vomiting and neck stiffness occurred when the patient stood upright. The symptoms disappeared in the supine position and the CSF pressure was lower than 7 cmH2O. Cerebrospinal fluid pressure returned to normal when clinical symptoms eased. CONCLUSIONS: Understanding the clinical manifestations of primary hypcroscopic pressure syndrome, cerebrospinal fluid pressure is crucial, sometimes confounded with intracranial hypertension
