Title: Exploration of carotid artery elasticity in children with simple obese by echo tracking imaging technique
Abstract: Objective To explore the elasticity of carotid artery in children with simple obese by echo tracking imaging technique.Methods Intima-media thickness (IMT), resistent index (RI), pulsatility index(PI ), the ratio of systolic phase and diastolic phase(S/D ) of common carotid artery (GCA) were detected differently in 50 simple obese children (obese group) and 50 normal children (control group) by CDFI.Internal systolic diameter (Ds), internal diastolic diameter (Dd),pressure-strain elastic moduhs(E ρ ), stiffness parameter ( β ), arterial compliance (AC), augmentation index (AI), pulse wave velocity ( PWV β ) were calcuhted automatically by means of echo tracking system.Results There was no significant difference in Ds,Dd,RI, PI,S/D and AI'between two groups (P >0.05).In obese group, IMT was significantly thicker,E ρ,β, PWV β were significantly higher,and AC was significantly lower thon those in control group (P < 0.05).Conclusions It has alteration of early atherosele in carotid artery of simple obese children.Echo tracking imaging technique is a quick, noninvasive, accurate and quantitative evaluating method for the elasticity of carotid artery.
