Abstract
In “Comparison of Symmetrical Hemodialysis Catheters Using Computational Fluid Dynamics” ( 1 Clark T.W.I. Isu G. Gallo D. Verdonck P. Morbiducci U. Comparison of Symmetric Hemodialysis Catheters using Computational Fluid Dynamics. J Vasc Interv Radiol. 2015; (In press) PubMed Google Scholar ), Clark and coworkers use computational fluid dynamics (CFD) to analyze the hemodynamics of three symmetric permanent hemodialysis catheters. Based on previous publications, the hemodynamic characteristics that may influence catheter function are identified and described, and then CFD is used to quantify and compare these characteristics between catheters. The catheters are evaluated based on how effectively they display positive characteristics including: less thrombogenic flow patterns, less shear-induced platelet activation, less recirculation, and greater flow deflection angle. Comparison of Symmetric Hemodialysis Catheters Using Computational Fluid DynamicsJournal of Vascular and Interventional RadiologyVol. 26Issue 2PreviewSymmetric-tip dialysis catheters have become alternative devices because of low access recirculation and ease of tip positioning. Flow characteristics of three symmetric catheters were compared based on computational fluid dynamics (CFD) as they relate to catheter function. Full-Text PDF Open Access
