组织多普勒评价健康成人颈总动脉弹性

目的探讨TDI评价颈总动脉弹性的可行性及获取健康成人CCA壁运动指标的正常值.方法分别对105例健康人连接ECG,并行右CCA超声检查,记录CCA的TDI曲线,并应用MedArchive Viewer软件测量CCA壁运动的时间、速度、加速度等相关指标.结果男性CCA弹性大于女性,以前壁为著;≤40岁组弹性比≥40岁组明显好.前后壁几乎同时运动,但方向相反,前壁运动幅度较后壁大.结论获得了健康成人CCA壁运动相关指标的正常值;应用TDI评价颈总动脉弹性技术可行,具有较高临床应用价值.

Tissue Doppler imaging in evaluating CCA elasticity of healthy adults

Objective To discuss the feasibility of TDI for evaluating CCA elasticity and investigate the correlative indexes of CCA walls pulsatility in healthy people. Methods The R CCA of 105 healthy adults were examined by ultrasound with simultaneous ECG monitoring. The curve of CCA wall pulsatility was recorded by TDI technology and MedArchive Viewer software was used to measure time, velocity, acceleration of CCA wall pulsatility, et al. Results The CCA elasticity of the male was better than that of the female, especially in the anterior wall. The CCA elasticity of the group of age under 40 was better than the groups of age over 40. Anterior walls almost simultaneously pulsatility with posterior walls, but their directions were opposite. Conclusion The correlative indexes of CCA wall pulsatility in healthy people were obtained in this research. TDI can evaluate CCA elasticity, which has great clinical value.
