Contrast enhanced magnetic resonance venography in the follow-up evaluation of idiopathic intracranial hypertension patients with cerebral venous sinus stenting

Role of contrast-enhanced magnetic resonance venography (CE-MRV) in the follow-up of venous sinus stenting (VSS) among the idiopathic intracranial hypertension (IIH) patients. Prospective evaluation of VSS patients with CE-MRV, DRCV and DSA for follow-up of clinically suspected recurrent stenosis. C...

Description
Summary:Role of contrast-enhanced magnetic resonance venography (CE-MRV) in the follow-up of venous sinus stenting (VSS) among the idiopathic intracranial hypertension (IIH) patients. Prospective evaluation of VSS patients with CE-MRV, DRCV and DSA for follow-up of clinically suspected recurrent stenosis. CE-MRV was evaluated against DRCV and DSA. Ten patients with twelve episodes of recurrent symptoms. Sensitivity, specificity, PPV, NPV and accuracy of the CE-MRV for the detection of recurrent stenosis were: 100%, 33.33%, 81.82%, 100% and 83.3% respectively. CE-MRV was a reliable first-line investigation for the detection of recurrent stenosis following VSS. •MRV was not validated against DRCV or DSA for follow-up evaluation of VSS in IIH patients.•CE-MRV has 100% sensitivity and NPV to detect recurrent stenosis following venous sinus stenting in IIH.•TOF MRV was suboptimal for evaluation of recurrent stenosis due to susceptibility artifact from the native stent.•CE-MRV was 100% concordant with DRCV and DSA in the evaluation of stent patency, VOL patency and recurrent stenosis.•CE-MRV should be the initial test for VSS follow-up and DRCV with manometry reserved for patients with equivocal CE-MRV.
