MENA Regional Endovascular Intervention for Venous Cerebral Venous Sinus Thrombosis
Starting soon · Not applicable
Conditions studied: Cerebral Venous Sinus Thrombosis
In brief
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.
