Analysis of the effect of stent porosity and shape on saccular intracranial aneurysm using the Lattice Boltzmann method

This article presents an analysis of blood flow patterns in intracranial saccular aneurysm and the effects of the shape and porosity of the stents used in endovascular treatments. In this study will be used the flow reduction criteria for characterizing the efficiency of the stent. The hemodynamic p...

In this study will be used the flow reduction criteria for characterizing the efficiency of the stent. The hemodynamic properties of a newtonian blood flow into the aneurysm will be evaluated using the Lattice Boltzmann method (LBM). Porosity values and stent forms are proposed for analysis. In all stent cases analyzed is observed a reduction of velocity and pressure and an increase in viscosity.

En este estudio se utilizarán los criterios de reducción de flujo para caracterizar la eficiencia del stent. Las propiedades hemodinámicas del flujo sanguíneo newtoniano hacia el aneurisma se evaluarán utilizando el método Lattice Boltzmann (LBM). Se proponen valores de porosidad y formas de stent para el análisis. En todos los casos de stent analizados se observa una reducción de la velocidad y la presión y un aumento de la viscosidad. Se observa además que el stent de contorno rectangular es el caso óptimo y reduce la magnitud de la velocidad de flujo dentro del aneurisma hasta en un 76%. Los resultados ayudan a comprender el papel de la porosidad en la forma y el diseño de un stent.application/pdfspaUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/1680http://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/1680Copyright (c) 2013 D S Ayala, D A MaderoAcceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 9, No 18 (2013)Analysis of the effect of stent porosity and shape on saccular intracranial aneurysm using the Lattice Boltzmann methodAnálisis del efecto de la porosidad y forma de un stent en un aneurisma sacular intracranealarticleinfo:eu-repo/semantics/articlepublishedVersioninfo:eu-repo/semantics/publishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Saccular Intracranial AneurysmStentLattice Boltzmann MethodAneurisma Intracraneal SacularStentMétodo De Enrejado De BoltzmannAyala, D Sa3740bc0-fa1c-4d02-b898-d715c249bd89-1Madero, D A2d1f5f98-ce64-46f2-bd38-f6def9b06e0e-1Oncólogos del Occidente S.AIngeniería y Ciencia9183359ing.cienc.ORIGINALdocument (18).pdfdocument (18).pdfTexto completo PDFapplication/pdf3270126https://repository.eafit.edu.co/bitstreams/860a4653-0a5a-42b9-8110-42d6f2618c32/download9faaa6fdd221cd2405dee84fd36d8f12MD51articulo.htmlarticulo.htmlTexto completo HTMLtext/html374https://repository.eafit.edu.co/bitstreams/6fd55edf-f6e3-45e1-bba2-3b82882ae4cc/download885827724ec4a6fcc47cda7de58a2e22MD53THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/46ba5a88-0dca-430d-8533-2e627df90e2e/downloadda9b21a5c7e00c7f1127cef8e97035e0MD5210784/14422oai:repository.eafit.edu.co:10784/144222024-12-04 11:48:55.004open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co
