Evaluation of elasticity of carotid artery in perimenopausal women by velocity vector imaging / 中华超声影像学杂志

ABSTRACT

Objective To discuss the change of elasticity of common carotid artery(CCA) with velocity vector imaging(VVI) technique in perimenopausal women.Methods 68 women in perimenopausal period were divided into two groupsestrogen drop group(42 women) and normal control group(26 women) according to the level of estrogen in serum.All women were examined with color Doppler ultrasound,and the maximum time to peak of the velocity(VTTP),maximum velocity(Vmax),maximum radial strain (Smax),maximum strain rate(SRmax) and the change rate of area(ΔS) were measured and assessed in common carotid artery(CCA) including 6 segmentsanterior wall,posterior wall,anterolateral wall,anterior internal wall,posterolateral wall and posterointernal wall.Results There were signicantly differences of the elastic parameters between two groups inculding VTTP,Smax and ΔS (P ＜0.01),and there were no statistical difference on the Vmax and SRmax in both two groups(P ＞0.05).Conclusions The change of elasticity in CCA can be observed susceptibly with VVI in perimenopausal women,and VVI is an effective and sensitive technique for detecting CCA elastic characteristics.
