Comparison of 2-Year Angiographic Outcomes of Stent- and Nonstent-Assisted Coil Embolization in Unruptured Aneurysms with an Unfavorable Configuration for Coiling

Abstract

The present study did not show that additional hemodynamic and biologic effects of stents designed for neck remodeling were enough to enhance progressive occlusion and prevent the recanalization of unruptured aneurysms. Our finding suggests that stent placement provides no better long-term angiographic outcomes for unruptured aneurysms with an unfavorable configuration for coiling.
