Hemodynamics of Flow Diverters

Journal of Biomechanical Engineering, 2017
Cerebral aneurysms are pathological focal evaginations of the arterial wall at and around the junctions of the circle of Willis. Their tenuous walls predispose aneurysms to leak or rupture leading to hemorrhagic strokes with high morbidity and mortality rates.

A mini-review of intrasaccular flow diverters

Journal of NeuroInterventional Surgery, 2022
Treatment of wide-necked complex intracranial aneurysms continues to challenge neurointerventionalists. Intrasaccular flow diverters have expanded the armamentarium considerably and are now used extensively. While five types of devices have already obtained the CE mark for use within Europe, only the Woven EndoBridge (WEB) device is approved by the US ...

Modeling Flow Diverters Using a Porous Medium Approach: A Fast Alternative to Virtual Flow Diverter Deployment

World Neurosurgery, 2022
The Tubridge flow diverter (FD) (MicroPort Medical Co. Ltd., Shanghai, China) is a novel device aimed at reconstructing the parent artery and eliminating the aneurysm. Numerical simulations based on virtual FD deployment allow the assessment of the complex nature of aneurismal flow changes before the actual intervention but are demanding on ...

Flow diverters for intracranial aneurysms

Innovative Neurosurgery, 2015
Abstract The progressive establishment of endovascular management in treating intracranial aneurysms had lead to continuous technique advancements and development of innovative technologies. Flow diverters are “stent-like” devices currently used for complex unruptured aneurysms allowing endoluminal reconstruction of the parent artery and

Treatment with flow diverter stent during pregnancy

Neuroradiology, 2020
Intracranial aneurysms are rarely diagnosed during pregnancy. If treatment is necessary, surgery was traditionally preferred over embolization in case of ongoing pregnancy, due to concerns regarding foetal radiation exposure. We present a case of 21 mm unruptured carotid-ophthalmic aneurysm diagnosed during pregnancy and treated with flow diversion ...

Evaluation of a novel flow diverter, the DiVeRt system, in an animal model

Journal of NeuroInterventional Surgery, 2021
BackgroundUsing a surgical aneurysm model, this study assessed the performance of a new flow diverter (FD), the DiVeRt, and evaluated the angiographic and histologic features at different periods after stent deployment.MethodsFifteen New Zealand White rabbits were treated 3 days prior to intervention and until euthanization with dual antiplatelets ...

Baka ritual flow diverted

Hunter Gatherer Research, 2015
Ethnographers of Congo Basin hunter-gatherers have emphasised ritual as a levelling mechanism that strengthens community spirit and mediates power evenly between individuals and subgroups. Pursuant to recent research with a Baka community in Cameroon, now largely abandoning the hunter-gatherer lifestyle, I analyse the mutual causal interactions between

Flow Diverter

Flow Diverter
The flow diverter is a relatively new but revolutionary technology in the realm of Endo vascular management of complex cerebral aneurysms. The traditional approach in the past has been stent deployment assisted coil embolisation. However, this maybe associated with partial occlusion or late recanalisation of the aneurysm.

Flow diverter treatment of cerebral blister aneurysms

Neuroradiology, 2017
Blood blister-like aneurysms (BBA) are small, friable, broad-based aneurysms that represent high risk for rerupture. Treatment of BBA is challenging, and may include surgical wrapping, clipping, multiple overlapping stents, and/or coiling. Flow diversion is a rapidly evolving treatment strategy for intracranial aneurysms, but the evidence for its use ...

Flow Diverter Treatment of Tandem Intracranial Aneurysms

World Neurosurgery, 2017
To assess technical success and clinical and imaging outcomes of flow diversion (FD) treatment of multiple, tandem intracranial aneurysms.Retrospective analysis was performed of patients treated with FD for tandem intracranial aneurysms.Twenty female patients with a mean (±SD) age of 60 (±12) years were included.
