Investigation of physiological pulsatile flow in a model arterial stenosis using large-eddy and direct numerical simulations [PDF]

, 2012
Physiologicalpulsatileflow in a 3D model of arterialstenosis is investigated by using largeeddysimulation (LES) technique. The computational domain chosen is a simple channel with a biological type stenosis formed eccentrically on the top wall.

Aortic stenosis [PDF]

European Journal of Echocardiography, 2005
Aortic stenosis is a common finding at echocardiography. This review describes the assessment of the aortic valve, the left ventricle, and the rest of the heart. It discusses grading the stenosis including cases in which there are discrepancies between the different echocardiographic measurements.

Utility of Blood Flow/Resistance Index Ratio (Qx) as a Marker of Stenosis and Future Thrombotic Events in Native Arteriovenous Fistulas

Frontiers in Surgery, 2021
Objective: The resistance index (RI) and the blood flow volume (Qa) are the most used Doppler ultrasound (DUS) parameters to identify the presence of stenosis in arteriovenous fistula (AVF).

Association of developmental lumbar spinal canal stenosis and stunting

Indian Spine Journal, 2021
Objective: To determine a possible relationship between developmental lumbar spinal canal stenosis (DLSS) and stunting. Background: Stunting is due to failure of longitudinal length with shortened long bones. Stunted individuals have failure of growth of

The effect of varying degrees of stenosis on transition to turbulence in oscillatory flows [PDF]

arXiv, 2022
Many complications in physiology are associated with a deviation in flow in arteries due to a stenosis. The presence of stenosis may transition the flow to weak turbulence. The degree of stenosis as well as its configuration whether symmetric or non-symmetric to the parent artery influences whether the flow would stay laminar or transition to ...
