本文分析４５例原发性低频压综合征的临床表现，诊断和治疗。全部病例均有坐立时头痛、眩晕等，二例癫痫样发作。腰穿压力＜０．６８６ｋＰａ，其中１０例负压；脑脊液合少许红细胞白细胞，蛋白含量增高。经头低足高位休息，补充大量液体，鞘内注射生理盐水，一般３周左右恢复，预后良好。文中提出原发性低颅压综合征可能与病毒感染、身体状况不佳有关，其发病机理是否与脊髓蛛网膜下腔调节障碍或／和蛛网膜颗粒样结构吸收增强有关。
This article analyzes 45 cases of primary low pressure syndrome clinical manifestations, diagnosis and treatment. All cases were sitting immediately headache, dizziness, etc., two cases of epileptic seizures. Waist wear pressure <0.686kPa, of which 10 cases of negative pressure; cerebrospinal fluid combined with a small red blood cell leukocytes, protein content increased.
