目的分析下肢深静脉血栓早期诊断中检测血浆D-二聚体的临床价值。方法分析该院于2016年3月—2017年3月期间接收的120例DVT患者资料,并将其作为实验组,另选取同期行健康体检者100例设为对照组,对比并分析2组检测结果。结果与对照组(235.68±56.28)μg/L相比,实验组D-二聚体水平(4012.52±1749.26)μg/L更高(P<0.05)。血浆D-二聚体检测对DVT诊断特异性、敏感性分别为47.83%、100%;作为DVT预测因子,阴性与阳性预测值分别为100.00%、88.99%。结论 D-二聚体检测具能够动态检测、无创、快速等优点,可作为DVT排除试验,可被临床推广、应用。
Objective To analyze the clinical value of detecting plasma D-dimer in the early diagnosis of deep venous thrombosis of lower extremities. Methods The data of 120 DVT patients received from March 2016 to March 2017 in the hospital were analyzed and used as the experimental group. Another 100 healthy subjects were selected as the control group during the same period. The two groups of tests were compared and analyzed result. Results Compared with the control group (235.68 ± 56.28) μg / L, the D-dimer level in the experimental group (4012.52 ± 1749.26) μg / L was higher (P <0.05). The diagnostic sensitivity and specificity of plasma D-dimer for DVT were 47.83% and 100%, respectively. The negative and positive predictive values of DVT as predictors of DVT were 100.00% and 88.99%, respectively. Conclusion D-dimer test can be dynamically detected, non-invasive, fast and so on, can be used as DVT exclusion test, which can be clinically promoted and applied.
