【摘要】 目的 应用彩色多普勒研究糖尿病肾病患者颈动脉血流动力学的改变。方法 检测30例非肾病和30例糖尿病肾病患者就颈部血管各项测值进行对比,同时对血管内径内膜中层厚度进行测量分析。结果 糖尿病肾病组较对照组颈动脉损伤明显.表现为颈动脉斑块形成,病变组共28例,占93％,对照组11例,占36.7％。内膜增厚,病变组为14例,其中1例患者存在较严重的颈动脉狭窄,狭窄程度大于50％。对照组4例。动脉阻力指数升高明显,动脉搏动指数升高也较明显,收缩期峰值血流速度明显增高,舒张末期流速降低。结论 糖尿病肾病患者颈动脉有较明显损伤,内膜增厚,粥样斑块发生率明显增高。CDFI诊断颈动脉病变准确可信.有重要临床价值。更多还原

【Abstract】 Objective To study the hemodynamic changs of carotid artery of patients with renal diabetic. Methods All carotid arteries of 30 patients with renal diabetic was examined with color ultrasonography and vascular diameters, intima-media thickness, plaques were measured and compared with 30 patients without renal diabetic. Results The abnormal signs of carotid arteries such as plaque formation and IMT thinking and vascular constriction were found in 28 cases of 30 patients with renal diabetic and total lesion detection rate was up to 93%. Eleven cases with plaque formation were checked out in control group and lesion detection rate was up to 36.7%. There was significant difference between the two groups the RI, PI and PSV were increased significantly, and EDV decreased. Conclusions The damnifications of carotid arteries such as IMT thinking, plaque formation in patients with renal diabetic are increased significantly. CDFI is proved a reliable methods for evaluating the pathological changes of carotid arteries, which has vital clinical significance.更多还原
