摘要
自发性低颅压综合征(SIH)是一种以体位性头痛为主要特征的临床综合征,可表现为眩晕、恶心、步态不稳、不同程度的意识障碍等,甚至威胁生命安全.SIH临床诊断的主要方法是头颅磁共振成像(MRI),可见幕上幕下弥漫性硬脑膜增厚、硬膜下积液、脑下移、脑垂体充血等,其复杂的临床症状及影像学特征极易造成误诊漏诊,延误治疗,影响患者预后.目前SIH治疗以卧床休息及补液治疗为主,大多数患者预后良好,少数患者需行硬脑膜修复治疗.因此,本文针对SIH的临床症状、诊断方法、治疗现状进行简要综述,以加强临床对SIH诊疗的认识.
Abstract
Spontaneous intracranial hypotension(SIH)is a clinical syndrome characterized by orthostatic head-ache,manifesting as vertigo,nausea,unsteady gait,different degrees of disturbance of consciousness,etc.It may even threaten people's health and life.As the main clinical diagnosis method for SIH,brain magnetic resonance imaging(MRI)shows supratentorial and subtentorial diffuse dural thickening,subdural effusion,brain moving up,pituitary hyper-emia,etc.Complex clinical symptoms and imaging features can easily lead to misdiagnosis and missed diagnosis,delay-ing the treatment and affecting the prognosis.Currently,the treatment for SIH is based on bed rest and fluid replacement therapy.Most patients have a good prognosis,and a few patients need dural repair.Herein,clinical symptoms,diagnostic methods,and treatment status of SIH were briefly reviewed to strengthen clinical understanding of diagnosis and treat-ment of SIH.
