目的探讨彩超在诊断老年2型糖尿病下肢动脉阻塞性病变中的应用价值。方法选择老年2型糖尿病下肢动脉阻塞性病变98例为观察组,97名健康志愿者为对照组,均接受双下肢动脉彩超检查。测量并比较两组间下肢动脉血管管径狭窄、管腔闭塞、管壁斑块及血流量情况。结果①观察组中,彩色多普勒超声共显示下肢动脉斑块、管腔狭窄及管腔闭塞的比例分别为62.24%、74.49%和24.49%,显著高于对照组(P<0.01)。②观察组患者股动脉、腘动脉及足背动脉血管内径分别为(6.32±0.55)mm、(4.97±0.82)mm及(1.56±0.32)mm,均明显窄于对照组(P<0.01)。其股动脉、腘动脉及足背动脉血流量分别为(37.9±7.2)mm3/s、(11.8±2.8)mm3/s和(0.9±0.4)mm3/s,均明显低于对照组(P<0.01)。结论在2型糖尿病并发下肢动脉血管病变的诊断中,彩超具有能够准确的评价动脉管壁、管腔及血流动力学情况,具有较高的应用价值。
Objective To explore the value of color Doppler ultrasonography in the diagnosis of occlusive arterial occlusive disease of lower extremity in type 2 diabetes mellitus in the elderly. Methods Ninety-eight elderly patients with obstructive arterial occlusive disease of lower extremity type 2 diabetes mellitus were selected as observation group and 97 healthy volunteers as control group, all underwent double-lower extremity arterial ultrasonography. The arterial diameter of lower extremity was narrowed, lumen occlusion, plaque wall and blood flow were measured and compared between the two groups. Results ① In the observation group, color Doppler ultrasound showed 62.24%, 74.49% and 24.49% of lower extremity artery plaque, lumen stenosis and lumen occlusion, which were significantly higher than those of the control group (P <0.01). ② The diameter of femoral artery, popliteal artery and dorsalis pedis artery were (6.32 ± 0.55) mm, (4.97 ± 0.82) mm and (1.56 ± 0.32) mm respectively in the observation group, which were significantly narrower than those in the control group (P <0.01). The blood flow of the femoral artery, popliteal artery and dorsalis pedis artery were (37.9 ± 7.2) mm3 / s, (11.8 ± 2.8) mm3 / s and (0.9 ± 0.4) mm3 / s, 0.01). Conclusion In the diagnosis of type 2 diabetes mellitus complicated with lower extremity arterial disease, color Doppler ultrasonography has the ability to accurately evaluate the arterial wall, lumen and hemodynamics, and has a high value.
