Computational fluid dynamic characterization of carotid bifurcation stenosis in patient-based geometries
Hemodynamic forces play a role in determining endothelial cell (EC) phenotype and influence vascular remodeling. We present a lesion-based computational fluid dynamic (CFD) pilot analysis to understand the complex spatial and temporal hemodynamic changes that prevail in patients with high-grade carotid artery stenosis (CS). High-resolution three-dimensional (3D) rotational angiography datasets ...
متن کاملReconstruction of carotid bifurcation hemodynamics and wall thickness using computational fluid dynamics and MRI.
A thorough understanding of the relationship between local hemodynamics and plaque progression has been hindered by an inability to prospectively monitor these factors in vivo in humans. In this study a novel approach for noninvasively reconstructing artery wall thickness and local hemodynamics at the human carotid bifurcation is presented. Three-dimensional (3D) models of the lumen and wall bo...
متن کاملCatheter dilatation of proximal carotid stenosis during distal bifurcation endarterectomy.
Although the deliberate therapeutic dilatation of arteriosclerotic plaques was described more than 15 years ago, clinical acceptance of the technique has been slow [1]. Since Gruntzig and Hopff [2] developed a tough, reliable, and easy to use polyvinylchloride balloon catheter, however, the applicability of the technique has been extended beyond the dilatation of the iliac, femoral , and renal ...
متن کاملEvaluation framework for carotid bifurcation lumen segmentation and stenosis grading
This paper describes an evaluation framework that allows a standardized and objective quantitative comparison of carotid artery lumen segmentation and stenosis grading algorithms. We describe the data repository comprising 56 multi-center, multi-vendor CTA datasets, their acquisition, the creation of the reference standard and the evaluation measures. This framework has been introduced at the M...
متن کاملComputational fluid dynamic analysis of RO membrane performance with novel feed spacer geometries
A finite element based numerical model has been employed to describe momentum and mass transfer in open and spacer-filled crossflow membrane channels. Simulations considering operating conditions typical of seawater (SW), brackish water (BW), and reuse water (RW) reverse osmosis (RO) applications are employed for optimization of hypothetical spiral wound element feed spacer designs. Preliminary...
