Hemodynamic-morphologic discriminants for intracranial aneurysm rupture.
BACKGROUND AND PURPOSE the purpose of this study was to identify significant morphological and hemodynamic parameters that discriminate intracranial aneurysm rupture status using 3-dimensional angiography and computational fluid dynamics. METHODS one hundred nineteen intracranial aneurysms (38 ruptured, 81 unruptured) were analyzed from 3-dimensional angiographic images and computational flui...
متن کاملHemodynamic changes in recurrent intracranial terminal aneurysm after endovascular treatment.
RATIONALE AND OBJECTIVES Multiple cases of recurrence of aneurysms after endovascular treatment have been reported. The purpose of the current hemodynamic study was to identify changes in shear stress and pressure associated with the recurrence of terminal intracranial aneurysms after endovascular occlusion. METHODS Using a finite element method, a pulsed flow with a non-Newtonian viscosity o...

Background and Aim: This study aimed to present the results of early and delayed operation on patients with ruptured brain aneurysms. In addition to comparing the results and rates of morbidity and mortality in the surgical procedure and identifying the effective factors, this study aimed to provide methods to improve the treatment of brain aneurysm. Methods and Materials/Patients: This was a ...
متن کاملHiFiVS Modeling of Flow Diverter Deployment Enables Hemodynamic Characterization of Complex Intracranial Aneurysm Cases
Object—Flow diversion via Pipeline Embolization Device (PED) represents the most recent advancement in endovascular therapy of intracranial aneurysms. This exploratory study aims at a proof of concept for an advanced device-modeling tool in conjunction with computational fluid dynamics (CFD) to evaluate flow modification effects by PED in real treatment cases. Methods—We performed computational...
متن کاملA Critical Role for Proinflammatory Behavior of Smooth Muscle Cells in Hemodynamic Initiation of Intracranial Aneurysm
BACKGROUND Intracranial aneurysm initiation is poorly understood, although hemodynamic insult is believed to play an important role in triggering the pathology. It has recently been found in a rabbit model that while macrophages are absent during hemodynamic aneurysm initiation, matrix metalloproteinases (MMPs) are elevated and co-localize with smooth muscle cells (SMCs). This study investigate...
