摘要
目的分析超声检查与血浆D-二聚体浓度诊断脑卒中患者下肢静脉血栓形成的价值。方法对95例脑卒中患者行下肢静脉超声检查与血浆D-二聚体浓度测定,判断有无下肢静脉血栓形成。结果D-二聚体和超声检查诊断下肢静脉血栓的敏感性、特异性、阳性预测值、阴性预测值、准确性分别为80.0%、76.2%、38.7%、95.3%、76.8%和86.6%、98.8%、92.8%、97.5%、96.8%。超声诊断的特异性、准确性及阳性预测值高于血浆D-二聚体浓度测定(P〈0.05)。结论血浆D-二聚体浓度可作为临床排除静脉血栓形成的可靠指标,超声检查对于诊断脑卒中患者下肢静脉血栓具有较高的诊断价值。
Objective To evaluate the value of ultrasound and plasma D - dimer in the diagnosis of lower limb venous thrombosis in stroke patients. Methods Ninety - five stroke patients enrolled in the study. Each patient was examined by lower limb venous ultrasound, and the plasma D- dimer was measured. Results The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of plasma D - dimer and ultrasonography were 80%, 76.2 %, 38.7 %, 95.3 %, 76.8 % and 86.6%, 98.8%, 92.8%, 97.5%, 96.8%, respectively. The specificity, positive predictive value and accuracy of ultrasonography were higher than those of plasma D - dimer. Conclusion Plasma D - dimer can be a reliable index to excluding venous thrombosis in clinic, and ultrasonography has high value in the diagnosis of lower limb venous thrombosis in stroke patients.
