Computational Fluid Dynamic Simulation of the Flow through Venous Valve
The cause of varicose veins remains unidentified, despite their high incidence. The purpose of this study was to investigate the role of the blood flow through venous valves in the pathogenesis of varicose veins, using a computational fluid dynamics (CFD) simulation. A complex vortex flow with a large apparent first eddy and a small second deep eddy were observed in all models. The presence of a venous sinus significantly altered vortex formation, which was considered to affect the retention and deposition of platelet aggregates in the valvular pocket. This is thought to be a part of the mechanism of thrombus formation in venous-valve pockets that consequently leads to varicose vein formation.
