摘　　要：目的探讨血管回声跟踪技术(echo-tracking,ET)检测肥胖儿童干预治疗前后肱动脉弹性参数改变及意义。方法应用ET技术检测43例肥胖儿童干预治疗前、后双侧肱动脉弹性系数(Eρ)、硬化度(β)、顺应性(AC)、膨大系数(AI)、脉搏波传导速度(PWVβ)及内中膜厚度(IMT),分析干预治疗前、后各参数变化情况。结果肥胖儿童干预治疗前后比较:治疗后Eρ、β及PWVβ均降低,差异有统计学意义(P<0.05),AC、AI增高,但无统计学差异(P>0.05),IMT无明显变化。结论 ET技术能定量反映肥胖儿童干预治疗前后肱动脉弹性状况。Objective To detect the brachial artery elasticity in obese children by echo tracking technique（ET） pre and post intervention therapy. Methods ET technology was used to measure obese children＇s elastic modulus （ Ep）. stiffness constant （β）, arterial compliance （ AC）, augmentation index（ AI）. pulse wave velocity（PWVβ） and inti ma-media thickness（ IMT）, which were also analyzed afterwards. Results Compared with pre and post intervention therapy, Eρ,β and PWVβwere lower.with significant difference （P〈0.05）. AC and AI were higher, but with statisti cal significance （P〈0. 05） ,and no change in IMT. Conclusions ET technology can detect brachial arrery elasticity in obese children.
