Review Meta Analysis
Carotid Artery Stenting Versus Carotid Endarterectomy for Treatment of Asymptomatic Carotid Artery Stenosis.
Asymptomatic carotid stenosis is common and is associated with increased risk of stroke. The relative efficacy and safety of carotid endarterectomy (CEA) and carotid stenting (CAS) in patients with asymptomatic carotid stenosis remain unclear. Five studies that recruited patients with asymptomatic but significant carotid stenosis, who underwent CEA or CAS, were included in this systematic review and meta-analysis. ⋯ In the subgroup analysis, the decreased risk of MI after CAS was significant only in the mixed patients group. CAS was associated with higher risk of stroke but lower risk of MI than those with CEA. Both procedures appeared equivalent in terms of the risk of death.
