Abstract:
Objective To assess the elasticity change of common carotid artery in early stage of atherosclerosis in patients with type 2 diabetes by velocity vector imaging(VVI).Methods Sixty patients with type 2 diabetes were divided into group A(32 cases)and group B(28case)according the vascular complications(including Macroangiopathy and Microangiopathy).Patients without vascular complications belong to group A,others belong to group B.Fifty-eight healthy volunteers were supplied as normal control group.Time to the peak of velocity(VTTP),maximum of velocity(Vmax),maximum of strain(Smax),and maximum of strain rate(SRmax)of six segment(anterolateral wall,anterior wall,anteromedial wall,posteromedial wall,posterior wall,posterolateral wall)were measured,which were supplied by VVI automatic analysis software.Results VTTP,Smax and SRmax had no significant differences in any segments intra-group A,B and control group(P＞0.05).Vmax had significant differences in some segments in control group,group A and group B,Vmax of anterior wall,anterolateral wall and posterolateral wall were higher than those of posterior wall,posteromedial wall and anteromedial wall(P＜0.05).VTTP,Vmax,Smax and SRmax of corresponding segments had significant differences among group A,group B and control group(P＜0.05),control group＞group A＞group B(P＜0.05).Conclusions The change of common carotid elasticity can be detected in early stage of atherosclerosis in patients with type 2 diabetes by VVI.
