老年II型糖尿病患者下肢动脉彩超检测及临床意义

Low extremity artery color Doppler imaging in elderly patients with type II diabetes mellitus and its clinical significance

目的:探讨老年II型糖尿病患者下肢动脉彩超检测及其临床意义。方法:对60例老年糖尿病患者(患者组)下肢动脉作自上而下的超声检测,测量血管的内径、中-内膜层(IMT)、粥样斑块及血流频谱,与同龄正常人进行比较。结果:①患者组IMT、粥样斑块较对照组明显增厚(P<0.01)。②患者组下肢动脉明显狭窄段检出率为12.64%、闭塞段检出率为1.39%,明显高于对照组的3.19%和0(P<0.01),90.11%的明显狭窄段和91.30%的闭塞段位于膝关节以下管径较小动脉。③18.8%的无症状老年糖尿病患者存在动脉明显狭窄和闭塞,患者组中有肢体症状者动脉狭窄和闭塞的检出较无症状者多。结论:高分辨率B超可清楚地显示老年II型糖尿病患者下肢动脉内膜和斑块,结合CDFI及频谱检测可以对狭窄程度和闭塞作出判断,尤其适于膝关节以下管径较小的动脉。
