彩色多普勒超声在下肢动脉粥样硬化诊断中的应用价值

Color Doppler Ultrasound in Lower Limb Arteriosclerosis Diagnosis Application Value

目的探讨在下肢动脉粥样硬化诊断中应用彩色多普勒超声的可行性和应用价值。方法对在该院行彩色多普勒超声诊断的下肢动脉粥样硬化患者临床资料,观察二维(2D)和彩色多普勒血流显像(CDFI)情况。结果下肢动脉粥样硬化A组、B组和C组患者在2D、CDFI及脉冲多普勒显像上差异明显,与正常对照线比较差异有统计学意义(P<0.05)。结论彩色多普勒超声既可清晰地2D上显示患者血管病变的解剖结构改变,还可借助CDFI获取详细的下肢血管内血流动力的信息,是目前无创性检查下肢动脉粥样硬化的首选检查手段,建议临床推广应用。

Objective To investigate the diagnosis in lower limb atherosclerosis in the application of color Doppler ultrasound on the feasibility and application value. Methods In my hospital by color Doppler ultrasound in diagnosis of lower limb atherosclerosis in patients with clinical data, observation of two-dimensional（2D） and color Doppler flow imaging （CDFI） condition. Results The atherosclerosis of lower extremity A group, B group and C group of patients in the 2D, CDFI and pulsed Doppler imaging difference is apparent, with significant difference in comparison with normal control line（P＆lt;0.05）. Conclusion Color Doppler ultrasound can be clearly displayed on the 2D in patients with vascular lesions of the anatomical changes, can also use CDFI to obtain detailed stopping blood flow dynamic information, is currently the noninvasive diagnosis of lower limb atherosclerosis of choice examination means, recommendations for clinical popularization and application.
