Intrasaccular flow-disruption treatment of intracranial aneurysms: preliminary results of a multicenter clinical study.
BACKGROUND AND PURPOSE The endovascular treatment of intracranial aneurysms with unfavorable anatomy (large aneurysms, wide-neck) is frequently challenging and is also associated with a high incidence of significant recurrences. The WEB, an intrasaccular flow disrupter, was designed for use in this type of aneurysm. We report our early experience with this device in this multicenter study. MA...
متن کاملComputational fluid dynamics modeling of intracranial aneurysms: effects of parent artery segmentation on intra-aneurysmal hemodynamics.
PURPOSE The purpose of this study is to show the influence of the upstream parent artery geometry on intraaneurysmal hemodynamics of cerebral aneurysms. METHODS Patient-specific models of 4 cerebral aneurysms (1 posterior communicating artery [PcomA], 2 middle cerebral artery [MCA], and 1 anterior communicating artery [AcomA]) were constructed from 3D rotational angiography images. Two geomet...
متن کاملComputational fluid dynamic analysis of intracranial aneurysmal bleb formation.
BACKGROUND The management of unruptured aneurysms is controversial, with the decision to treat influenced by aneurysm characteristics including size and morphology. Aneurysmal bleb formation is thought to be associated with an increased risk of rupture. OBJECTIVE To correlate computational fluid dynamic (CFD) indices with bleb formation. METHODS Anatomic models were constructed from 3-dimen...
متن کاملComputational fluid dynamics analysis on recurrence of simple coiling intracranial aneurysms with remnant neck
Background: Hemodynamic factors are considered to play an important role in the initiation and recurrence of cerebral aneurysms. However, hemodynamic characteristics leading to the recurrence of aneurysms is not well recognized. This study analyzes the hemodynamics of simple-coiling and remnant-neck aneurysms, and discusses the impact of hemodynamic factors on the recurrence of cerebral aneurys...
متن کاملInfluence of hemodynamic factors on rupture of intracranial aneurysms: patient-specific 3D mirror aneurysms model computational fluid dynamics simulation.
BACKGROUND AND PURPOSE Hemodynamics factors play an important role in the rupture of cerebral aneurysms. The purpose of this study was to evaluate the impact of hemodynamic factors on the rupture of the MANs with 3D reconstruction model CFD simulation. MATERIALS AND METHODS RDSA was performed in 9 pairs of intracranial MANs. Each pair was divided into ruptured and unruptured groups. The hemod...
