目的探究彩色多普勒超声诊断糖尿病下肢血管病变的临床效果。方法选取2016年6月—2017年3月进行超声诊断的46例糖尿病下肢血管病变患者作为观察组,选取同时期46例前来体检的人员作为对照组。两组均采用彩色多普勒超声进行诊断,观察两组的股动脉、腘动脉内-中膜厚度,下肢动脉内径(股动脉、腘动脉、胫后动脉、足背动脉),以及下肢血管病变发生率。计量资料采用t检验,计数资料采用χ~2检验,P<0.05为差异有统计学意义。结果观察组股动脉内-中膜厚度、腘动脉内-中膜厚度[(1.22±0.23)、(1.12±0.19)mm]与对照组[(0.73±0.34)、(0.72±0.18)mm]比较,差异有统计学意义(均P<0.05),对照组的血流量高于观察组,血管内径大于观察组,频谱宽度较之观察组更窄,差异有统计学意义(均P<0.05)。观察组的血管闭塞、血栓、内膜增厚及斑块、50%以上血管狭窄等下肢动脉硬化发生率[21.74%、8.70%、82.61%、41.30%]均高于对照组[0.00%、0.00%、8.70%、6.52%],差异有统计学意义(均P<0.05)。结论彩色多普勒超声技术对于糖尿病下肢血管病变患者的诊断效果显著,为后续治疗提供诊断依据。
Objective To investigate the clinical effect of color Doppler ultrasonography in the diagnosis of diabetic lower extremity vascular disease. Methods Forty-six patients with diabetic lower extremity vascular disease undergoing ultrasound diagnosis from June, 2016 to March, 2017 were selected as the observation group and 46 individuals who came to the same period were selected as the control group. Both groups were diagnosed by color Doppler ultrasound and the femoral artery, 腘 artery intima-media thickness, arterial diameter of the lower extremities (femoral artery, 腘 artery, posterior tibial artery, dorsalis pedis artery), and lower extremity vascular lesions Occurrence rate. Measurement data using t test, count data using χ ~ 2 test, P <0.05 for the difference was statistically significant. Results Compared with the control group [(0.73 ± 0.34), (0.72 ± 0.18) mm], the intima-media thickness and the arterial intima-media thickness [(1.22 ± 0.23) and (1.12 ± 0.19) mm] , The difference was statistically significant (both P <0.05). The blood flow of the control group was higher than that of the observation group. The vascular diameter was larger than that of the observation group. The spectrum width was narrower than that of the observation group (all P <0.05). The incidence of lower extremity arteriosclerosis, such as vascular occlusion, thrombus, intima thickening and plaque in more than 50% of the cases in the observation group, was significantly higher than that in the control group [21.74%, 8.70%, 82.61%, 41.30% %, 8.70%, 6.52%], the difference was statistically significant (all P <0.05). Conclusion The color Doppler ultrasound has significant diagnostic value for patients with diabetic lower extremity vascular disease and provides the basis for follow-up treatment.
