Recruiting NA Carotid Endarterectomy

New treatment option for Carotid Endarterectomy

Official title Carotid Endarterectomy and Stenting Timing

ClinicalTrials.gov ID: NCT06898151

What this study is testing

What it's testing
To compare the safety and efficacy of carotid revascularization performed within 48 hours versus after 14 days in patients with symptomatic carotid stenosis accompanied with MRI-confirmed acute infarction (high signal on diffusion-weighted imaging accompanied by low apparent diffusion coefficient signal) in the responsible vascular territory.
