Coiling Techniques in management of Cerebral Aneurysms Preoperative assessment, Outcome and Complications [PDF]

Minia Journal of Medical Research, 2019
Background: according to the International Subarachnoid Trial (ISAT), patients with subarachnoid hemorrhage (SAH) fared better with endovascular coiling than those with surgical clipping (Molyneux et al., 2005).

Use of a flow diverter with antegrade-retrograde coil embolization for an unruptured persistent primitive trigeminal artery aneurysm

Interdisciplinary Neurosurgery, 2022
Persistent primitive trigeminal artery (PPTA) is the most common primitive carotid-basilar anastomosis, and it is associated with cavernous aneurysms.

Optimization of flow diverters for cerebral aneurysms [PDF]

Journal of Computational Science, 2012
Abstract A modern technique to treat cerebral aneurysms is to insert a flow diverter in the parent artery. In order to produce an optimal design of such devices, we consider a methodology combining simulated annealing optimization and lattice Boltzmann simulations.

Effect of Flow Diverter Porosity on Intraaneurysmal Blood Flow [PDF]

Clinical Neuroradiology, 2009
Growth and rupture, the two events that dominate the evolution of an intracranial aneurysm, are both dependent on intraaneurysmal flow. Decrease of intraaneurysmal flow is considered an attractive alternative for treating intracranial aneurysms by minimally invasive techniques.

Compacting a Single Flow Diverter versus Overlapping Flow Diverters for Intracranial Aneurysms: A Computational Study [PDF]

American Journal of Neuroradiology, 2017
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.Using a high-fidelity virtual stent placement method, we simulated 3 flow-diverter strategies (single noncompacted, 2

Abstract Number ‐ 82: Central Retinal Artery Metallic Embolus After Ophthalmic Segment Internal Carotid Artery Aneurysm Flow‐diverter Embolization

Stroke: Vascular and Interventional Neurology, 2023
Introduction Flow‐diverting stents are effective devices in treating what would have previously been difficult to treat aneurysms such as wide‐necked, fusiform, blood blister, or giant aneurysms.

Overview of Different Flow Diverters and Flow Dynamics

Neurosurgery, 2019
Abstract Over the past decade, flow diverter technology for endocranial aneurysms has seen rapid evolution, with the development of new devices quickly outpacing the clinical evidence base. However, flow diversion has not yet been directly compared to surgical aneurysm clipping or other endovascular procedures.

Blood flow in intracranial aneurysms treated with Pipeline embolization devices: computational simulation and verification with Doppler ultrasonography on phantom models [PDF]

Ultrasonography, 2015
Purpose: The aim of this study was to validate a computational fluid dynamics (CFD) simulation of flow-diverter treatment through Doppler ultrasonography measurements in patient-specific models of intracranial bifurcation and side-wall aneurysms. Methods:

Two patients of visual disturbance and optic perineuritis after placement of a flow diverter

Radiology Case Reports, 2022
The pathogenesis of new visual symptoms after flow diverter stent placement in the ophthalmic artery for internal carotid artery aneurysms remains unclear. We report two cases of patients who developed visual field disturbance and decreased visual acuity
