Comparative analysis of the results of interventional and surgical treatment for stenotic atherosclerosis of the carotid arteries

Abstract

Aim. Improving the short- and long-term outcomes of carotid artery stenting (CAS) and ca
rotid endarterectomy (CEA) in patients with significant carotid stenosis by optimizing diag
nostic methods to select the most appropriate treatment modality.
Material and methods. This prospective, non-randomized, observational clinical trial
included 100 patients with severe carotid artery stenosis (stenosis ≥70%) confirmed by
Doppler ultrasonography and CT angiography. Patients were allocated to either carotid
stenting (CAS) (n=50) or carotid endarterectomy (CEA) (n=50) using a decision-making
algorithm proposed by the authors based on diagnostic ultrasonography and CT angiog
raphy data.
Results. At 1-year follow-up, CAS and CEA demonstrated comparable rates of restenosis,
stroke freedom, and reintervention. This supports the idea that both CAS and CEA are effec
tive treatment options for preventing cerebrovascular events in patients with carotid artery
stenosis
