Physiological significance of helical flow in the arterial system and its potential clinical applications
X Liu, A Sun, Y Fan, X Deng - Annals of biomedical engineering, 2015 - Springer
Helical flow in the human aorta is possibly a typical example of 'form follows function'in the
vascular system. The helical blood flow may provide guaranties for the inner surface of the …

Helical flow as fluid dynamic signature for atherogenesis risk in aortocoronary bypass. A numeric study
The main purpose of the study was to verify if helical flow, widely observed in several
vessels, might be a signature of the blood dynamics of vein graft anastomosis. We …

Segment-specific associations between local haemodynamic and imaging markers of early atherosclerosis at the carotid artery: an in vivo human study
Low and oscillatory wall shear stress (WSS) has long been hypothesized as a risk factor for
atherosclerosis; however, evidence has been inferred primarily from model and post-mortem …
