2型糖尿病患者踝臂指数与下肢血管超声检查的相关性

The correlation between ankle-brachial index and ultrasonography in lower extremities vascular in type 2 dia- betic patients.

目的探讨2型糖尿病(T2DM)患者踝臂指数(ABI)与下肢血管超声检查结果的相关情况。方法检查218例 T2DM 患者的 ABI 并行双下肢血管超声检查,根据超声检查结果将下肢血管病变情况分为6种,并根据其严重情况进行评分,以 ABI 值与超声检查评分值进行相关性分析;同时以不同范围 ABI 值及超声检查结果将患者分组,比较各组间血管超声检查结果及 ABI 值的差异。结果 ABI 值越低,下肢血管超声检查结果病变程度越严重。ABI 与超声检查评分呈显著负相关(r=0.65,P<0.01)。在 ABI 为0.9～1.09组中,有部分患者存在下肢的血管病变。结论 ABI 及血管超声检查均能较好反映 T2DM 患者的下肢血管病变情况,ABI 越低下肢血管超声检查结果病变程度越严重;ABI 为0.90～1.09的 T2DM 患者中已有部分血管超声检查存在下肢血管病变。

Objective To investigate the correlation between ankle-brachial index and ultrasonography in lower ex- tremities vascular in type 2 diabetic patients.Methods 218 type 2 diabetic patients were enrolled,and ankle-brachial index(ABI)measurements and uhrasonography in lower extremities vascular were performed in all patients.Lower extremi- ties vascular disease(LEVD)were divided into six species according to the uhrasonography results and scored in accord- ante with its serious degree,then investigate the correlation between ABI and uhrasonography results score.All patients were divided into deferent groups according to uhrasonography results and ABI range,and then compared their deference. Results The lower the ABI,the more serious of the LEVD showed by ultrasonography.ABI and ultrasonic inspection score was significantly negatively correlated(r=-0.65,P<0.01).While ABI was 0.90～1.09,some patients already had LEVD.Conclusion Both ABI and vascular uhrasonography can reflect the LEVD in patients with type 2 diabetes, The lower the ABI,the more serious of the LEVD showed by ultrasonography.Vascular ultrasonography showed that some patients with type 2 diabetes already had LEVD while ABI was 0.90～1.09.
