REVIVE-CVST is a multicenter, prospective, randomized, open-label, blinded-endpoint (PROBE) trial evaluating whether early endovascular thrombectomy (EVT) combined with standard anticoagulation improves outcomes compared to anticoagulation alone in patients with severe cerebral venous sinus thrombosis (CVST).
The study targets adult patients (aged 18 years or older) presenting within 14 days of symptom onset with imaging-confirmed CVST and at least one severity marker, such as a Glasgow Coma Scale score of 14 or below, intracerebral hemorrhage, venous infarction, or deep venous system involvement.
Participants will be randomly assigned in a 1:1 ratio to either the intervention arm (EVT plus anticoagulation) or the control arm (anticoagulation alone). The primary endpoint is functional outcome at 180 days as measured by the modified Rankin Scale (mRS), using a shift analysis across all mRS categories.
The trial aims to enroll 440 participants across approximately 15 centers in the Middle East, North Africa, South Asia, and Turkey (MENA-SINO network). The study duration is approximately 42 months, including 18 months of enrollment and 12 months of follow-up for the last enrolled patient.

Inclusion Criteria:
* Age 18-65 years, inclusive
* Radiologically confirmed cerebral venous sinus thrombosis (CVST) by CT venography (CTV), MR venography (MRV), or digital subtraction angiography (DSA), with thrombosis of at least one major dural sinus
* Acute or subacute presentation with symptom onset within 21 days of randomization
* MRI phase characterization confirming acute or subacute phase
* At least one risk factor for poor outcome: symptoms of intracranial hypertension (severe headache, papilledema, visual obscurations), focal neurological deficit, seizures, altered consciousness (GCS 9-14), intracranial hemorrhage from venous congestion, or deep venous system thrombosis
* Significant venous outflow obstruction on imaging
* Written informed consent from patient or legally authorized representative
Exclusion Criteria:
* Isolated cortical vein thrombosis without dural sinus involvement
* Isolated cavernous sinus thrombosis
* Chronic-phase CVST on MRI phase characterization
* Pre-morbid modified Rankin Scale (mRS) score greater than 2
* Glasgow Coma Scale (GCS) score less than 9 at randomization
* Imminent risk of transtentorial herniation requiring emergent decompressive craniectomy
* Massive cerebral edema with midline shift greater than 10 mm requiring surgical intervention
* Active systemic bleeding or hemorrhagic diathesis
* Severe allergy to iodinated contrast media
* CVST secondary to active hematological malignancy or life expectancy less than 12 months
* Pr…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
