Key result
In a 3D-printed experimental model of carotid artery stenosis, the radial sectional velocity exhibited a plateau-like distribution with similar velocity in the central region (>65% of channel width).
Why the study?
Due to a lack of flow field measurements in carotid stenosis vessels, commonly assumed velocity distributions can cause wall shear stress estimates to vary by over 40%, affecting mechanical analysis accuracy.

No immediate clinical implications for carotid stenosis; extends experimental models for wall shear stress estimation.
Experimental and numerical simulation of carotid artery stenosis revealed a plateau-like radial velocity distribution, improving the accuracy of wall shear stress estimation.
Song et al. (2022) studied Carotid artery stenosis. 3D-printed experimental model and microparticle image velocimetry was evaluated on Radial sectional velocity distribution and wall shear stress. In a 3D-printed experimental model of carotid artery stenosis, the radial sectional velocity exhibited a plateau-like distribution with similar velocity in the central region (>65% of channel width).
