摘要:
目的 探讨实时剪切波弹性成像技术在评价下肢深静脉血栓(DVT)分期及溶栓疗效中的应用价值。 方法 选取212例DVT患者为研究对象,结合发病时间长短与彩色多普勒超声检查结果将其分为急性期组(n=97)、亚急性期组(n=68)、慢性期组(n=47),全部患者均接受溶栓治疗,根据治疗结果将其分为治愈组(n=83)、有效组(n=97)、无效组(n=32),采用剪切波弹性成像技术测定不同分期、不同疗效患者杨氏模量值,通过绘制ROC曲线评估治疗后血栓杨氏模量对DVT患者溶栓疗效的诊断效能。 结果 治疗前,不同分期DVT患者血栓杨氏模量的差异有统计学意义(P<0.05),其中急性期组<亚急性期组<慢性期组(P<0.001);治疗后,各组血栓杨氏模量低于治疗前(P<0.05),且各组治疗后血栓杨氏模量差异有统计学意义(P<0.05),其中急性期<亚急性期<慢性期(P<0.001)。治疗后,不同预后DVT患者血栓杨氏模量差异有统计学意义(P<0.05),其中治愈组<有效组<无效组(P<0.001)。ROC分析结果显示,当Youden指数取最大值0.632时,血栓杨氏模量截断值为6.825 kPa,此时诊断DVT患者溶栓治疗无效的敏感度为93.8%,特异性为69.4%,曲线下面积为0.885。 结论 实时剪切波弹性成像技术测定杨氏模量,可作为评价DVT分期及溶栓疗效的辅助手段。 Abstract:Objective To investigate the application value of shear wave elastography in the staging and thrombolytic efficacy of deep venous thrombosis (DVT) of lower extremities. Methods A total of 212 patients with DVT were selected as the research objects.The patients were divided into acute phase group (n=97), subacute phase group (n=68), chronic phase group (n=47) according to the time of onset and the results of color Doppler ultrasonography. According to treatment outcome, all patients received thrombolytic therapy and were divided into cure group (n=83), effective group (n=97), ineffective group (n=32). The shear wave elastography technique was used to measure the Young's modulus of patients with different stages and different therapeutic effects. The ROC curve was drawn to evaluate the diagnostic efficacy of Young's modulus of thrombolysis in patients with DVT after treatment. Results Before treatment, there were statistically significant differences in young's modulus of thrombus in patients with different stages of DVT (P<0.05), including acute stage group<subacute stage group<chronic stage group (P<0.001). After treatment, the young's modulus of thrombus in all groups was lower than before (P<0.05), and the difference was statistically significant (P<0.05), among which the acute stage<subacute stage<chronic stage (P<0.001). After treatment, young's modulus of thrombus in DVT patients with different prognosis had statistical significance (P<0.05), among which cured group<effective group<invalid group (P<0.001). ROC analysis results showed that when Youden index was 0.632, the cut-off value of Young's modulus of thrombolysis was 6.825 kPa, and the sensitivity, specificity and AUC for diagnosing ineffective thrombolytic therapy in DVT patients were 93.8%, 69.4% and 0.885 respectively. Conclusion The measurement of Young's modulus by shear wave elastography technique can be used as an auxiliary method to evaluate stage of DVT and the efficacy of thrombolysis. -
