Flow-Diverter Stent for the Endovascular Treatment of Intracranial Aneurysms
Background and Purpose—The purpose of this study is to report our preliminary experience with the flow-diverter Silk stent for the endovascular treatment of intracranial aneurysms. Methods—This prospective study was approved by the authors’ ethical committees. Twenty-nine patients with 34 fusiform or wide-necked unruptured aneurysms were included and treated by Silk stent placement alone by 2 p...
متن کاملCompacting a Single Flow Diverter versus Overlapping Flow Diverters for Intracranial Aneurysms: A Computational Study.
BACKGROUND AND PURPOSE Locally compacting the mesh of a flow diverter by a dynamic push-pull technique can accelerate intracranial aneurysm healing. We asked how this deployment strategy compares with overlapping 2 flow diverters for aneurysmal flow reduction. MATERIALS AND METHODS Using a high-fidelity virtual stent placement method, we simulated 3 flow-diverter strategies (single noncompact...
متن کاملThe FRED flow-diverter stent for intracranial aneurysms: clinical study to assess safety and efficacy.
BACKGROUND AND PURPOSE Flow-diverter stents are emerging for the endovascular treatment of difficult-to-treat or otherwise untreatable cerebral aneurysms (wide-neck, fusiform, dissecting, blisterlike, or giant). We assessed the clinical safety and efficacy of the Flow-Redirection Endoluminal Device. MATERIALS AND METHODS This was an institutional review board-approved single-center observatio...
متن کاملHemodynamic Effect of Flow Diverter and Coils in Treatment of Large and Giant Intracranial Aneurysms.
BACKGROUND This study aimed to investigate the hemodynamic changes induced by a flow diverter (FD) and coils in the treatment of internal carotid artery aneurysms, as well as to evaluate the effect of this treatment by using angiographic follow-up data. METHODS Six large and giant aneurysms were treated by the Tubridge FD and loose packing coils between June 2013 and May 2015. Patient-specifi...
متن کاملFailure of Flow Diverter Treatment of Intracranial Aneurysms Related to the Fetal-type Posterior Communicating Artery
PURPOSE The pipeline embolization device (PED) is a flow diverter that has shown promise in the treatment of intracranial aneurysms. Close to one-fifth of aneurysms, however, fail to occlude after PED placement. This study aims to identify anatomical features and clinicopathologic factors that may predispose failed aneurysm occlusion with the PED. MATERIALS AND METHODS We retrospectively revi...
