脑静脉窦血栓形成的临床特点及误诊分析

Clinical features and misdiagnosis of cerebral venous sinus thrombosis

目的探讨脑内静脉窦血栓形成的临床特点,降低误诊率。方法回顾分析55例脑内静脉窦血栓形成的临床资料。结果发病年龄以青壮年为主,男女均可患病,起病形式可急可缓,症状体征表现多样,影像学表现既可为出血也可缺血,脑脊液压力均升高,细胞学可正常,也可轻度异常。一旦确诊,肝素抗凝,预后良好。结论脑静脉窦血栓形成的临床表现缺乏特异性,MRV及DSA可以确诊,可存在解剖异常现象,需综合考虑才能减少误诊。

Objective To explore the clinical features of cerebral venous sinus thrombosis and to decrease the misdiagnostic accuracy.Methods The clinical data of 55 CVST patients were analyzed retrospectively.Results Cerebral venous sinus thrombosis especially often occurred in young adults,including men and women.The performance of CVST was complex,acute or subacute clinical characteristics,various symptoms and signs,the cerebral infarction or hemorrhage found out by imaging.Cerebrospinal fluid pressure was increased in all cases.CSF results may be normal or mildly abnormal.Once diagnosed,heparin,the prognosis was good.Conclusion The symptoms of CVST have no specificity.MRV and DSA can make diagnosis.In order to reduce the rate of misdiagnosis,we should take all examination results into account,considering anatomical abnormalities.
