目的探讨彩超对糖尿病下肢血管病变的诊断价值。方法选取2009年10月—2012年12月收治的糖尿病下肢血管发生病变的患者60例为观察组,选取非糖尿病患者60例为对照组,两组患者平卧,使用相同的彩色超声多普勒诊断仪器。测量两组患者的血管内径、内中膜厚度,观察管壁有无狭窄、斑块,血管有无充盈缺损情况等。计数资料采用χ2检验,P<0.05为差异有统计学意义。结果观察组检出血管病变52例,检出率86.7%,血管内径减少26.7%,内中膜增厚36.7%,管壁狭窄60.0%,血管内出现斑块71.7%,血管充盈缺损30.0%。对照组血管内径减少3.3%,内中膜增厚5.0%,管壁狭窄16.7%,血管内出现斑块18.3%,血管充盈缺损11.7%。两组比较差异均有统计学意义(均P<0.05)。结论彩超对糖尿病下肢血管病变具有重要的诊断价值和临床意义,值得在临床普遍推广应用。
Objective To investigate the diagnostic value of color Doppler ultrasonography in diabetic lower limb vascular disease. Methods Sixty patients with lower extremity angiogenesis in diabetes mellitus from October 2009 to December 2012 were selected as the observation group. Sixty non-diabetic patients were selected as the control group. The two groups were supine with the same color Doppler Diagnostic equipment. Two groups of patients were measured vascular diameter, thickness of the intima, the wall was observed with or without stenosis, plaque, vascular filling defect situation. Count data using χ2 test, P <0.05 for the difference was statistically significant. Results In the observation group, 52 cases of vascular lesions were detected, the detection rate was 86.7%, the vessel diameter was reduced by 26.7%, the intima-membrane thickening was 36.7%, the vessel wall was narrowed by 60.0%, the vessel was plaque was 71.7% and the vessel filling defect was 30.0%. The control group had a decrease of 3.3% in vessel diameter, 5.0% in intimal thickening, 16.7% in vessel wall stenosis, 18.3% in vessel and 11.7% in vascular filling defect. The differences between the two groups were statistically significant (P <0.05). Conclusion The color Doppler ultrasonography has important diagnostic value and clinical significance for diabetic lower extremity vascular lesions and should be widely applied in clinical practice.
