Flow Diverters in the Treatment of Pediatric Cerebrovascular Diseases [PDF]

American Journal of Neuroradiology, 2016
There is very limited data concerning utilization of flow diverters in children. Our aim is to report results for the treatment of complex intracranial aneurysms and carotid cavernous fistulas by using flow diverters in children.Retrospective review of children (17 years of age or younger) treated with flow diverters between May 2011 and July 2014 was ...

Surpass Evolve flow diverter in the treatment for complex wide neck ruptured internal carotid artery aneurysm: technical report of two cases with brief literature review

Egyptian Journal of Neurosurgery
Background Treatment of complex wide neck internal carotid aneurysm is technically difficult with both surgical as well as endovascular therapy. In this study, we work with flow diverter device to construct vascular lumen which diverts the blood flow ...

P49 Experimental Flow Visualization of a Flow Diverting Stent in a Popliteal Aneurysm

Artery Research, 2020
Purpose: Flow diverting stents are commonly used in saccular cerebral aneurysms [1]. Their use has not yet been investigated for popliteal aneurysms, which are commonly fusiform in nature and exposed to pulsatile triphasic flows.

Prediction of obliteration of unruptured cerebral aneurysm by residual aneurysm volume after flow diverter stent treatment

World Neurosurgery: X
Introduction There is no methodology to predict aneurysm occlusion using residual volume after flow diverter stent treatment. We retrospectively examined whether residual aneurysm volume at 6 months postoperatively can predict the degree of aneurysm ...

Multi-objective optimization of a porous diverter plate for a liquid-cooled micro-jet heat sink via surrogate modeling

Case Studies in Thermal Engineering
This work reports on the optimization of a porous diverter plate for a micro-jet heat sink to obtain the optimum jet nozzle diameter and flow opening ratio, which play a significant role in the cooling characteristics of heat sinks for electronic chips ...

Radiopaque FeMnN-Mo composite drawn filled tubing wires for braided absorbable neurovascular devices

Bioactive Materials
Flow diverter devices are small stents used to divert blood flow away from aneurysms in the brain, stagnating flow and inducing intra-aneurysmal thrombosis which in time will prevent aneurysm rupture.

Delayed Aneurysmal Rupture Following Flow Diverter Placement despite adjunctive coiling: Case report

Case Reports in Neurology
Introduction: Flow diverters significantly alter the inflow dynamics of an aneurysm, leading to both qualitative and quantitative changes in the intra-aneurysmal hemodynamic environment.
