高频超声在糖尿病下肢动脉粥样硬化病变诊断中的应用价值

目的应用高频探头对283例糖尿病患者下肢动脉血管进行检测,旨在发现糖尿病人下肢动脉有无病变及病变特点,为下肢动脉硬化闭塞性疾病的诊治提供有价值的信息。方法应用高频探头对糖尿病患者双下肢动脉进行逐一扫查,测量血管内径、内膜-中层（IMT）厚度,观察有无斑块、测量斑块大小。应用彩色多普勒（CDFI）观察管腔血流充盈状态、方向、性质,应用脉冲多普勒（PW）观察血流频谱并测量、记录。结果 283例糖尿病患者中,动脉粥样硬化发生率达85.2%,斑块出现率达74.9%,而斑块在膝以下动脉的发生率明显高于膝以上动脉,说明糖尿病人更易出现下肢远端组织溃疡、坏疽。结论高频超声具有无创、实时、可重复、直观、价廉等特点,成为糖尿病下肢动脉粥样硬化的检查首选,并为进一步进行造影及治疗提供重要信息。

High frequency ultrasonography in diagnosis of atherosclerosis in lower limbs of patients with diabetes.

Objective To apply high frequency ultrasonography for detection of arteriopathy in lower limbs of 283 patients with diabetes mellitus in order to find out the possible pathological changes and pathological characteristics,so as to provide valuable information for diagnosis of atherosclerosis obliterans in lower limbs.Methods High frequency ultrasonography had been applied for examination of arteries in lower limbs.The inner diameter and IMT thickness of blood vessels were measured.The size of plaques was ob...
