踝臂指数对透析患者血管钙化的评估价值

The Relationship Between Ankle Brachial Index and Vascular Calcification in Maintenance Dialysis Patients

目的:了解踝臂指数对维持性透析患者血管钙化的评估价值。方法:纳入我院血液净化中心130例维持性透析患者,记录相关临床资料,完善实验室检查,以X线片(双手正位、骨盆平片、腹部侧位片、胸部正侧位片)评价血管钙化情况,无创性全自动动脉测量仪检查踝臂指数。以t检验及相关分析了解踝臂指数与血管钙化的关系。结果:踝臂指数单因素分析中,踝臂指数在血管钙化评分总分≥3分组明显低于血管钙化总评分<3分组,髂动脉、股动脉、尺动脉钙化组ABI值低于无钙化组。双变量相关分析中,踝臂指数均与骨盆平片钙化评分、血管钙化评分总分负相关。以上结果有统计学意义。结论:踝臂指数与血管钙化评分有良好的相关性,踝臂指数的减少对中动脉钙化的评估意义较大。

Objective： To evaluate the meaning of ankle brachial index to vascular calcification in maintenance dialysis patients. Methods： One hundred and thirty patients in maintenance dialysis wear enrolled in this study. The related clinical data was included and recorded. The examination of X- ray（ chests,lateral abdomens,pelvis and hands） was done to estimate vascular calcification in patients. Ankle brachial index was measured by non- invasive arterial measuring instrument,to analyze the relationship between pulse wave velocity and vascular calcification using t- test and Spearson analysis. Results： By univariate analysis,ankle brachial index was significantly lower in patients with a vascular score ≥3 than that 〈3,ankle brachial index was significantly lower in patients with calcification in iliac arteries,Femoral arteries and ulnar artery than that in non- calcification group. By bivariate correlation analysis,Ankle brachial index was negatively associated with vascular calcification scores respectively in plain radiographic films of pelvis and in total. Conclusion： Ankle brachial index was a good index to evaluate calcification of medium- sized arteries.
