Clinical Trial Summary

A multicenter, prospective, outcome-assessor-blinded, randomized controlled trial study (MOSCASH) is designed to compare the efficiency of distal and proximal embolism protection devices during carotid angioplasty and stenting (CAS) procedure of patients with high-intensity signal in the plaque on the time-of-flight magnetic resonance angiography(TOF-MRA) .


Clinical Trial Description

CAS is an alternative to carotid endarterectomy(CEA) for treating carotid stenosis with a similar efficacy in preventing future stroke. High-intensity signal in the plaque on the TOF-MRA is associated to a high risk of cerebral embolism during stenting. The evidence of protection selection in such patients was limited. A multicenter, prospective, outcome-assessor-blinded, randomized controlled trial study (MOSCASH) is designed to compare the efficiency of distal and proximal embolism protection devices during CAS procedure of patients with high-intensity signal in the plaque on the TOF-MRA. Asymptomatic patients with internal carotid artery stenosis ≥ 70% (NASCET) and symptomatic patients with a stenosis ≥ 50% who have a high-intensity signal in the relevant plaques on TOF-MRA will be included. Patients are randomized in two balanced groups (1:1) to receive CAS with either distal (Spider FX) or proximal (Mo.Ma Ultra) protection. The primary endpoint is the incidence of new cerebral ipsilateral ischemic lesions on the Diffusion Weighted Imaging(DWI) in 7-days post operation. Secondary endpoints include the number, size, location of new cerebral ischemic lesions on the DWI, procedural complications, stroke, myocardial infarction, and death in 7 days. ;
