Objective To discuss the application of cerebrovascular intervention technique in evaluating the correlation between cerebral venous sinus and idiopathic intracranial hypertension (ⅡH).Methods The clinical data,including complete related clinical signs and symptoms,laboratory results,magnetic resonance venography (MRV) findings,etc.,of 13 ⅡH patients were retrospectively analyzed.Under local anesthesia whole brain DSA was performed,and superselective catheterization of venous sinus was accomplished to perform sectional pressure measurement of sagittal sinus,transverse sinus,sigmoid sinus and jugular vein.Results Cerebral DSA examination revealed that venous sinus stenosis or occlusion was seen in 10 patients (76.9％),including transverse sinus (n=6),sigmoid sinus (n=3),and transverse sinus together with sigmoid sinus (n=l).Superselective pressure neasurement of venous sinus showed that the pressure difference between the two ends of the narrowed venous sinus was up to 120-580 mmH20 in these 10 patients.In 8 patients (61.5％,8/13) the venous sinus stenosis and/or occlusion might be implicated in the occurrence of ⅡH,in 2 patients (15.4％,2/13) the venous sinus stenosis might be secondary to ⅡH,and in 3 patients (23.1％,3/13) the venous sinus stenosis might bear no relationship to ⅡH.Conclusion Cerebrovascular interventional angiography combined with superselective pressure measurement of venous sinus can clearly identify the relationship between ⅡH and venous sinus
