Use of dual-layered stents in endovascular treatment of extracranial stenosis of the internal carotid artery. Results of a patient-based meta-analysis of 4 clinical studies
Objectives: The aim of this study was to evaluate the clinical efficacy of dual-layered mesh-covered carotid stent systems (DLS) for carotid artery stenting (CAS). Background: The need to minimize the risk for plaque debris prolapsing between stent struts following CAS has resulted in the development of DLS. Small clinical studies evaluating 2 available devices, Roadsaver and CGuard, have been recently published; none of these studies is sufficiently powered to test the role of common risk factors on the occurrence of stroke at 30 days post-CAS.
