Particle Image Velocimetry Measurements of the Flow-Diverting Effects of a New Generation of the eCLIPs Implant for the Treatment of Intracranial Bifurcation Aneurysms

Applied Sciences, 2020
Flow diverters (FDs) for the endovascular treatment of intracranial aneurysms are effective for sidewall aneurysms, but their use at a bifurcation is problematic because FDs only partially cover the aneurysm neck and impede flow into a daughter branch ...

Vorapaxar as an Alternative for Ticagrelor Resistance in Neuroendovascular Intervention

Stroke: Vascular and Interventional Neurology, 2021
Background Perioperative dual‐antiplatelet therapy for flow diversion limits thromboembolic complications. However, resistance to dual‐antiplatelet therapy medications remains a concern for neuroendovascular intervention.

Experimental Study on Water Diversion and Sediment Control at Water Intake Hub of Central Yunnan Water Diversion Project [PDF]

长江科学院院报
[Objective] For water intake projects, the arrangement of the intake location is of paramount importance, as it must ensure the required water diversion volume while simultaneously preventing excessive sediment from entering the diversion channels and ...

Experimental research on opening diversion piers at Xifeihe combined sluice-pump station

Shuili Shuiyun Gongcheng Xuebao, 2018
In view of the problems of raceway and diagonal flow (whirling flow and skew flow) during the operation of the Xifeihe combined sluice-pump station alone, the hydraulic model tests on the combined sluice-pump junction are carried out by use of the ...

Antiplatelet Therapy in Flow Diversion

Neurosurgery, 2019
Abstract Dual antiplatelet therapy is typically employed as a means to mitigate thromboembolic complications after deployment of flow diverters, most commonly consisting of aspirin with either clopidogrel, prasugrel, or ticagrelor. Recent studies have demonstrated at least similar efficacy for ticagrelor as compared to clopidogrel in the form

Experimental Study on Hydraulic Characteristics of Trapezoidal Control Gate with Upstream Water Diversion Outlets in Irrigation Area [PDF]

长江科学院院报
To support precise measurement and control of water volume in irrigation area, this study investigated the influence of diversion outlet on the flow pattern in front of control gate, as well as the variation laws of flow coefficient and head loss of ...

Flow diversion of a dissecting PICA aneurysm

Neurosurgical Focus: Video, 2022
A 47-year-old female with a history of a ruptured left posterior inferior cerebellar artery (PICA) aneurysm, status post coil embolization and retreatment for recurrence, presented with evidence of a recurrent dissecting PICA aneurysm. Given that these aneurysms are considered high risk and have a greater propensity for rupture than anterior ...

O-017 Repeat flow diversion for previously failed flow diversion: multicenter experience [PDF]

Oral Abstracts, 2020
Background Aneurysmal persistence after flow-diversion (FD) occurs in 5–25% of aneurysms which might necessitate further treatment. A frequently used retreatment paradigm utilizes the deployment of another flow-diverting device (FDD) in a telescoping fashion within the existing device. There are no current data evaluating this strategy.
