Brief Summary

The VEHICLE Registry is a multicenter observational study aimed at evaluating the management and outcomes of patients with Idiopathic Intracranial Hypertension (IIH) undergoing venous sinus stenting in the Middle East and North Africa (MENA) region. The study focuses on assessing clinical characteristics, treatment efficacy, safety, and the role of venous sinus stenting as a therapeutic modality in IIH.

Outcome Measures

Primary Outcomes (3)

  • Symptom Improvement

    Proportion of patients reporting significant improvement or resolution of IIH symptoms (headache, visual disturbances, tinnitus) at six months post-venous sinus stenting.

    Six months post-procedure.

  • Change in Papilledema Grade

    Improvement in papilledema grade assessed by fundoscopic examination using the Frisén scale from baseline to six months post-procedure.

    Six months post-procedure.

  • Quality of Life Improvement

    Change in Quality of Life (QOL) scores measured using a standardized questionnaire from baseline to six months post-procedure.

    Baseline and six months post-procedure.

Secondary Outcomes (4)

  • Stent Patency Rate

    Six months post-procedure.

  • Adverse Events

    Up to six months post-procedure.

  • Visual Field Improvement

    Six months post-procedure.

  • Cranial Neuropathy Resolution

    Six months post-procedure.

Interventions

Performed under general or local anesthesia. Targeted stenosis sites included the right transverse sinus, left transverse sinus, bilateral transverse sinuses, and right transverse and sigmoid sinuses. Stents used included Venous Sinus Stent (CWS), CASPER, PRTCS, and multiple stents where necessary. Post-procedure care included antiplatelet therapy and routine follow-up assessments

Healthy VolunteersNo
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Patients diagnosed with Idiopathic Intracranial Hypertension who are candidates for venous sinus stenting, recruited from multiple centers across the MENA region.

You may qualify if:

  • Adults aged 18 to 60 years.
  • Diagnosed with Idiopathic Intracranial Hypertension (IIH) based on the modified Dandy criteria, including:
  • Symptoms of increased intracranial pressure (e.g., headache, visual disturbances).
  • Elevated opening pressure (\>250 mm H₂O) on lumbar puncture with normal cerebrospinal fluid composition.
  • No evidence of intracranial pathology (e.g., mass lesion, hydrocephalus) on neuroimaging.
  • Presence of papilledema. Evidence of venous sinus stenosis on Magnetic Resonance Venography (MRV) or Digital Subtraction Angiography (DSA).
  • Refractory to medical therapy or intolerant to medications (e.g., acetazolamide).
  • Willingness to undergo venous sinus stenting. Provided informed consent for participation.

You may not qualify if:

  • Secondary causes of intracranial hypertension (e.g., cerebral venous sinus thrombosis, neoplasm).
  • Coagulopathies or contraindications to antiplatelet or anticoagulation therapy. Pregnancy or lactation. Incomplete baseline data or inability to complete follow-up assessments. Severe comorbid conditions that preclude endovascular procedures.

Data Sharing

IPD Sharing
Will share

The VEHICLE Registry plans to share de-identified individual participant data (IPD) to promote transparency and facilitate further research in the field of Idiopathic Intracranial Hypertension (IIH). Sharing this data aims to contribute to a better understanding of IIH management and outcomes, especially regarding venous sinus stenting in the Middle East and North Africa (MENA) region.

Shared Documents
STUDY PROTOCOL
Time Frame
Data will be available beginning 6 months after publication of the primary study results. Data availability will continue for a period of 5 years following the initial publication.
Access Criteria
Qualified researchers affiliated with academic institutions, research organizations, or medical institutions. Researchers who provide a methodologically sound research proposal that is approved by an independent review committee.
