超声定量技术用于2型糖尿病颈动脉血管病变诊断

目的：探讨超声定量技术对2型糖尿病颈动脉病变的应用价值。方法：选择2型糖尿病患者40例，分为糖尿病无高血压组（20例）和糖尿病合并高血压组（20例），另选择10例正常人作为对照，应用高频超声和超声定量技术测量双侧颈总动脉后壁内中膜厚度（IMT）最大值（IMTmax）及平均值（IMTmean）。结果：3组研究对象的IMTmax和IMTmean在左、右颈总动脉之间均无显著差异，糖尿病合并高血压组IMTmax与糖尿病无高血压组无显著差异，糖尿病合并高血压组IMTmean显著大于糖尿病无高血压组。结论：应用超声定量技术能尽早及全面反映糖尿病和糖尿病合并高血压患者的颈动脉血管病变，其测定颈动脉内中膜平均厚度较最厚值更具优越性。

The Application of IMT Quantification Technology in Assessing the Vascular Pathology of Carotid Artery in Patients with Type 2 Diabetes Mellitus

Objective: To explore the value of intima-media thickness quantification technology in evaluating the vascular pathology of carotid artery in patients with type 2 diabetes mellitus. Methods: A total of 50 cases were divided into three groups: diabetes group (n=20), diabetes with hypertension group (n=20) and normal control group (n= 10). We measured the maximum IMT by conventional ultrasonography and mean IMT by quantification technology. Results: The maximum IMT and mean IMT had no significant difference between right and left carotids in three groups. There were no significant difference in the maximum IMT between diabetes with hypertension and diabetes group . The mean IMT of carotid artery in diabetes with hypertension group were thicker than that in diabetes group. Conclusion: Of two parameters, mean IMT is superior to the maximum IMT in evaluating the vascular pathology of carotid artery in diabetes patients, Ultrasonic IMT quantification technology can be used to early reflect the vascular changes of diabetes and diabetes with hypertensioa
