原发性低颅内压综合征(Primary intracranial hypotension.PIH)是一种与腰穿后头痛相似的综合征,表现为头痛、恶心、呕吐及眩晕,直立时症状加重,平卧后缓解,脑脊液压力在70mmH_2O以上,不伴外伤。腰穿或其他导致脑脊液生成减少,吸收增加或脑脊液漏等情况。由于比较少见,一般书籍中不提及本病,为提高对本病的认识,现作简一介绍。 1 病因分类 低颅内压综合征可分为原发性和继发性两类。继发性者由多种原因引起,如腰穿后,外伤或手术引起的脑脊液漏,神经袖套撕裂,各种原因所致的脑血流量减少(休克、严重失水、脑动脉硬化、脑膜脑炎、尿毒症、严重 Primary intracranial hypotension (PIH) is a syndrome similar to lumbar puncture headache, manifested as headache, nausea, vomiting and dizziness, increased symptoms in uprightness, recuperation after supine, cerebrospinal fluid Pressure above 70mmH_2O, without trauma. Waist wear or other lead to decreased production of cerebrospinal fluid, increased absorption or cerebrospinal fluid leakage and so on. As relatively rare, the general book does not mention the disease, in order to improve awareness of the disease, is a brief introduction. 1 cause classification Low intracranial pressure syndrome can be divided into primary and secondary categories. Secondary causes are caused by a variety of causes such as cerebrospinal fluid leakage due to trauma or surgery, laceration of the nerve cuff, reduction of cerebral blood flow due to various causes (shock, severe dehydration, cerebral arteriosclerosis, Meningoencephalitis, uremia, severe
