Study on the characteristics of carotid wall shear stress in type 2 diabetes patients based on ultrasound vector flow imaging.

ABSTRACT:

Objectives

We aimed to quantitatively analyze wall shear stress (WSS) of the common carotid artery (CCA) and elucidate the relationship between WSS and cardiovascular disease (CVD) in patients with type 2 diabetes mellitus (T2DM) using ultrasound vector flow (V-Flow) imaging.

Methods

A total of 109 T2DM patients were selected as the DM group, while 49 healthy volunteers served as the control group. V-Flow examination of the bilateral CCA was conducted. The maximum wall shear stress (WSS_max) and mean wall shear stress (WSS_mean) at the bifurcation, proximal bifurcation and middle segment of the bilateral CCA were obtained.

Results

The DM group showed decreased WSS_mean in the middle region and proximal bifurcation of the CCA compared with
