Application effect of color Doppler ultrasound in diagnosis of lower extremity vascular disease in elderly patients with type 2 diabetes / 中国基层医药

ABSTRACT

Objective:To study the clinical value of color Doppler ultrasound in diagnosis of lower extremity vascular disease in elderly patients with type 2 diabetes.Methods:From May 2017 to February 2018, 40 elderly patients with type 2 diabetic lower extremity vascular disease diagnosed and treated in the Special Inspection Department of the Seventh People's Hospital of Shaoxing were selected as the observation group, and 40 healthy medical examinees in the same period were selected as control group.The results of Doppler ultrasound examinations of the two groups were compared.Results:The detection rates of atherosclerotic plaque, occlusion and stenosis in the observation group were higher than those in the control group(all P<0.05). The inner diameter of the posterior tibial artery, inner diameter of the dorsal foot artery in the observation group were (1.85±0.11)mm and (1.70±0.15)mm, respectively, which were smaller than those in the control group [(2.22±0.13)mm, (1.94±0.15)mm] ( t=13.741, 7.155, all P<0.05). The intima-media thickness of the tibial posterior artery and dorsal plantar artery in the observation group were (0.56±0.24)mm, (0.36±0.11)mm, respectively, which were thicker than those in the control group [(0.36±0.13)mm, (0.22±0.17)mm] ( t=55.337, 4.373, all P<0.05). There were no statistically significant differences in the inner diameter of the femoral artery and popliteal artery(all P>0.05). The thickness of the intima-media layer of the observation group was thicker than that of the control group(all P<0.05). The resistance index of the femoral artery, popliteal artery, posterior tibial artery and dorsal plantar artery of the observation group[(0.84±0.15), (0.88±0.11), (0.93±0.17), (1.01±0.22)] were larger than those of the control group[(0.65±0.10), (0.65±0.10), (0.70±0.13), (0.74±0.15)]( t=6.666, 9.785, 5.300, 6.413, all P<0.05). The detection rates of lower extremity artery stenosis(27.50%) and occlusion (10.0%) in the observation group were higher than those in the control group(7.50% and 0.00%), the differences were statistically significant(χ 2=5.54, 4.21, all P<0.05). Conclusion:Color Doppler ultrasonography in the diagnosis of lower extremity vascular lesions in elderly patients with type 2 diabetes can identify the lesions and has significant diagnostic value, which is worthy of application and promotion.
