Asymptomatic moderate carotid artery stenosis with intraplaque hemorrhage: onset of new ischemic stroke.

abstract：BACKGROUND:Experience with the endovascular treatment of cerebral aneurysms by flow diverter devices (FDDs) is limited to four devices (Pipeline, Covidien; FRED, Microvention; Silk, Balt Extrusion; Surpass, Stryker), as reported in different studies. OBJECTIVE:To describe the initial experience and the technical innov...
