Endarterectomy Versus Stenting in Patients With Symptomatic Severe Carotid Stenosis - 2

Condition(s) studied

Investigational drug(s) / intervention(s)

carotid endarterectomy: Carotid endarterectomy is a surgical procedure used to reduce the risk of stroke due to carotid artery stenosis. During an endarterectomy, the surgeon opens the artery and removes the plaque.

Carotid artery stenting: Carotid artery stenting is an endovascular procedure in which a stent is deployed in the lumen of the carotid artery to treat narrowing of the carotid artery and reduce the risk of stroke.

Study summary

Carotid stenosis caused by atherosclerosis is a significant risk factor for ischemic stroke, accounting for up to 15% of all strokes and transient ischemic attacks. Randomized clinical trials (RCTs) have demonstrated the benefits of carotid endarterectomy (CEA) in reducing stroke risk in patients with severe symptomatic carotid stenosis. Carotid artery stenting (CAS) has been developed as an alternative to CEA, offering several potential advantages, such as avoiding local surgical complications. However, unlike CEA, CAS has not been compared to medical therapy in RCTs for symptomatic carotid stenosis.

Eligibility

Primary outcome measure(s)

• DWI Lesion Detection Rate — From 3 days before procedure to 7 days after procedure
  Imaging endpoint : Proportion of patients having at least one new lesion on post-treatment Diffusion-Weigthed Imaging (DWI) MRI compared to pre-treatment DWI MRI and confirmed by a core lab. The pre-treatment DWI MRI will be performed within 3 days before procedure. The post-treatment DWI MRI will be performed within 7 days after procedure.
