Detailed Description
The DIVE-IIN-LATE trial is a multicenter randomized controlled trial designed to evaluate whether transverse sinus stenting is more effective than best medical therapy alone for patients with idiopath...
Eligibility Criteria
Inclusion
- Subject is ≥ 18 years old at inclusion.
- Subject with definite diagnosis of IIH satisfying the modified Dandy criteria (A to E) ) at the time of initial diagnosis, under BMM including ACZ for more than 1 year
- Patient with elevated intracranial pressure defined as \> 25 cm H20 or 18 mmHg
- Subject with intracranial TVS stenosis on dominant transverse sinus and hypoplastic contralateral one (or bilateral TVS stenosis) diagnosed on MRI
- Normal MRI findings excepted intracranial TVS stenosis or IIH related abnormalities
- Patient having received information about data collection and having signed and dated an Informed Consent Form
- Subjects must be able to attend all scheduled visits and to comply with all trial procedures
- Subjects must be covered by public health insurance
Exclusion
- Patients receiving topiramate in the previous month
- Known contrast product, Nickel, titanium allergy
- Exposure to an oral drug (other than ACZ), substance, or disorder that has been associated with elevation of intracranial pressure within 2 months of diagnosis (lithium, vitamin A, tetracycline and related compounds)
- History of intracranial venous thrombosis or intracranial neoplasia
- Fulminant decrease of visual acuity due to the IIH defined as a visual loss (of the most seriously impaired eye) of at least 3/10 (from corrected vision) within 4 weeks, in absence of any other ophthalmologic pathology and Mean Deficit of visual field superior to -10 dB
- Optic nerve atrophy
- Amblyopia
- Refractive error greater ±8 sphere or more than ±3 in cylinder in either eye if there are abnormalities in funduscopy (optic disc tilt, staphyloma), previous glaucoma, other disorders causing visual loss
- Pregnancy: if a woman is of childbearing potential a urine or serum beta HCG test is positive
- Patient with a severe or fatal comorbidity that will likely prevent improvement or follow-up or that will render the procedure unlikely to benefit the patient.
- Evidence of intracranial hemorrhage (subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), etc.)
- Life expectancy under 6 months
- Patients with renal failure (creatinine \> 1.5 mg/dl and/or creatinine clearance \< 60 mL/min, except if patient is already on hemodialysis)
- History of previously implanted intra-cranial sinus stent
- Previous gastric bypass surgery AAP-DGOS PHRC-N 22\_0175 CHU DE MONTPELLIER Pr Costalat Vincent/Pr Ducros Anne Version n°2.2 date 25/03/2025 Page 28 sur 63
- Contra-indication to general anesthesia
- Contra-indication to aspirin, clopidogrel or other P2Y12 anti-aggregant
- History of chronic obstructive pulmonary disease or other severe respiratory disease
- History of deep vein thrombosis or pulmonary embolism
- History of atrial fibrillation or other risks of stroke
- Cerebral vascular lesions (arteriovenous malformation, arteriovenous fistula, aneurysms, significant stenosis of extra- or intra-cranial vessels other than the targeted venous sinus stenosis, intracranial artery dissection, etc.).
- Anatomical anomaly of the venous sinus which would prevent safe catheterization and stenting
- Subject who are in a dependency or employment with the sponsor or the investigator
- Participation in another clinical trial or administration of an unapproved drug within the last 4 weeks before the screening date
- Subject protected according to the French Public Health Code (e.g. patients under law protection, prisoners, pregnant, parturient or lactating women, and patients under guardianship/curatorship)
