Carotid stenosis – basing treatment on individual patients’ needs. Optimal medical therapy alone or accompanied by stenting or endarterectomy

Abstract

Abstract. Though carotid artery stenosis is a known origin of stroke, risk assessment and treatment modality are not yet satisfactorily established. Guideline updates according to latest evidence are expected shortly. Current clinical weakness concerns in particular the identification of “at-risk” patients. Beside the symptomatic status and the degree of stenosis, further signs of unstable plaque on carotid and cerebral imaging should be considered. Moreover, medical and endovascular therapy are continuously improving. Randomized trials and meta-analyses have shown similar long-term results for protected carotid artery stenting and endarterectomy. However, endovascular revascularization was associated with an increased 30-day rate of minor strokes. Newly developed embolic protection devices could possibly compensate for this disadvantage. Furthermore, high-level optimal medical therapy alone is currently being evaluated comparatively. We assume that a comprehensive evaluation of plaque vulnerability, serious consideration of advanced embolic protection, and more space for optimal medical therapy alone according to latest evidence, will benefit patients with carotid stenosis.
