CEUS评价肝硬化门静脉高压患者TIPS术后分流道支架功能

CEUS in evaluating on the function of stent after TIPS in patients with portal hypertension in cirrhosis

目的探讨CEUS评价肝硬化门静脉高压患者TIPS术后分流道支架功能的应用价值。方法选取成功接受TIPS手术的肝硬化门静脉高压患者107例,分别采用CDFI与CEUS检测分流道支架功能,以DSA结果为金标准,比较二者诊断效能。结果CEUS诊断TIPS术后支架功能的敏感度、特异度、阳性预测值及阴性预测值分别为90.00%(9/10)、100%(16/16)、100%(9/9)及94.12%(16/17),CDFI分别为64.71%(11/17)、80.00%(68/85)、39.29%(11/28)及91.89%(68/74)。CDFI与CEUS诊断TIPS术后支架功能的AUC分别为0.542和0.958(P<0.01)。结论CEUS诊断TIPS术后分流道支架功能的敏感度和特异度均较高,可为临床提供更为客观准确的信息。

Objective To investigate the value of CEUS in evaluating on the function of stent after TIPS in cirrhosis patients with portal hypertension.Methods Totally 107 cirrhosis patients with portal hypertension who underwent TIPS were selected,and the function of stent were observed with CDFI and CEUS.Taken DSA results as golden standards,the diagnostic efficiency of CDFI and CEUS were evaluated and compared.Results The sensitivity,specificity,positive predictive value and negative predictive value of CEUS in evaluation on function of stent after TIPS was 90.00%(9/10),100%(16/16),100%(9/9)and 94.12%(16/17),while of CDFI was 64.71%(11/17),80.00%(68/85),39.29%(11/28)and 91.89%(68/74),respectively.Taken DSA results as gold standards,AUC of CDFI and CEUS was 0.542 and 0.958(P<0.01).Conclusion CEUS has high sensitivity and specificity for judgment of stent function after TIPS,which can provide objective and accurate information for clinical practice.
