Clinical trials

This study is a multicenter, prospective, randomized, open-label, blinded-endpoint clinical trial designed to evaluate the safety and potential efficacy of endovascular recanalization strategies in patients with symptomatic non-acute carotid artery occlusion and cognitive impairment. Eligible participants will be randomly assigned to best medical treatment alone, endovascular recanalization without proximal protection plus best medical treatment, or endovascular recanalization with proximal balloon protection plus best medical treatment. The study will assess whether endovascular recanalization improves cognitive function and whether proximal protection reduces procedure-related new ischemic lesions on diffusion-weighted magnetic resonance imaging.
