Incidence of cerebral venous sinus thrombosis in patients with idiopathic intracranial hypertension / 眼科

ABSTRACT

Objective To explore the rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Design Restrospective case series.Participants 92 cases with idiopathic intracranial hypertension.Meth- otis All patients diagnosed with papilledema from January 1,2000 through May 1,2007 at our ophthalmology center.Consecutive pa- tients with a diagnosis of papilledema were identified.Patients with space-occupying lesions,hydrocepbalus,or meningitis were excluded. The remaining patients were evaluated with lumbar puncture,magnetic resonance imaging(MRI)and magnetic resonance venography (MRV).Main Outcome Measures The rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Results Excluding patients with mass lesions,meningitis,or hydrocephalus,the occurrence of CVST was 7 (7.6%)of 92 patients with presumed IIH.One additional patients had a diagnosis of suspected CVST.Cerebral venous sinus thrombosis was diagnosed in 1 of the 7 patients with MRI alone,whereas it was evident in all 7 patients with MRV.Conclusions Cerebral venous si- nus thrombosis accounts for 7.6% of patients with presumed IIH in our ophthalmology services.Magnetic resonance venography in com- bination with MRI is recommended to identify this subgroup of patients.(Ophthalmol CHN,2007,16410-413)
