高频超声技术检测2型糖尿病患者指、趾尖动脉血流参数及其在早期血管病变中的筛查价值

High frequency ultrasonography for detecting blood flow parameters of fingertip and toe artery in patients with type 2 diabetes mellitus and its screening value in early vascular diseases

目的分析高频超声技术检测2型糖尿病(T2DM)患者指、趾尖动脉血流参数及其在早期血管病变中的筛查价值。方法选取2016年3月~2017年3月唐山市工人医院分院(以下简称"我院")90例T2DM患者为T2DM组,其中患病时间1~3年48例,>3~9年22例,>9~<16年11例,≥16年9例。选择同期于我院体检健康者90名为对照组。通过高频超声技术检测两组指、趾尖动脉血流参数的情况。结果 T2DM组患病时间为>3~9年、>9~<16年及≥16年的患者指尖动脉阻力指数明显高于对照组,血流量显著低于对照组,差异均有统计学意义(P<0.05);T2DM组患病时间>9~<16年和≥16年的患者指尖末梢动脉血管内径均明显低于对照组,差异均有统计学意义(P<0.05);T2DM组患病时间为>3~9年、>9~<16年、≥16年的患者趾尖末梢动脉的阻力指数明显高于对照组,血管内径与血流量均明显低于对照组,差异均有统计学意义(均P<0.05)。结论利用高频超声技术能够有效检测T2DM患者的指、趾尖动脉血流参数的情况,有助于筛查患者早期血管病变,故此有着重要的评估价值。

Objective To analyze the detection of high frequency ultrasonography in blood flow parameters of finger,toe tip artery and screening value of early vascular disease in patients with type 2 diabetes mellitus(T2DM).Methods From March 2016 to March 2017,90 cases of T2DM in the Workers′Hospital of Tangshan City("our hospital"for short)were selected as the T2DM group,among them,there were 48 cases with the disease duration of 1-3 years,22 cases with>3-9 years,11 cases with>9-<16 years,and 9 cases with≥16 years.Ninety healthy subjects in our hospital were selected as the control group at the same period.The blood flow parameters of finger and toe tip artery were detected by high frequency ultrasonography in the each group.Results The resistance index of finger tip artery in patients with the disease duration of>3-9 years,>9-<16 years and≥16 years in the T2DM group were significantly higher than those in the control group,and the blood flow were significantly lower than those in the control group,the differences were statistically significant(P<0.05).The finger tip peripheral arterial vascular diameter for patients with the disease duration of>9-<16 years and≥16 years in the T2DM group were significantly lower than those in the control group,the differences were statistically significant(P<0.05).The resistance index of toe tip artery for patients with the disease duration>3-9 years,>9-<16 years and≥16 years in the T2DM group were significantly higher than those in the control group,and the vascular diameter and blood flow were significantly lower than those in the control group,the differences were statistically significant(P<0.05).Conclusion Using high frequency ultrasonography can effectively detect the blood flow parameters of finger and toe tip artery in patients with T2DM,which can help to screen the early vascular lesion,so it has important assessment value.
