CTA在急性复杂性大咯血患者行介入栓塞术前的应用价值分析

本文探讨了CT血管造影(CT angiography,CTA)在急性复杂性大咯血患者行介入栓塞术前的应用价值。回顾性选择49例急性复杂性大咯血患者CTA影像资料,通过与术中数字减影血管造影(digital subtraction angiography,DSA)结果进行对比,发现CTA对罪犯血管诊断准确率为89.33%,对多动脉交通吻合诊断准确率为86.96%。Kappa检验CTA与DSA检查结果一致性较高,受试者特征曲线(ROC)分析CTA诊断急性复杂性大咯血罪犯血管的曲线下面积(AUC)为0.947(95%CI:0.903~0.990,P=0.000),灵敏度89.33%,特异度100.00%。通过随访发现CTA指导下行介入栓塞术治疗有效率91.84%,术后1年无大咯血复发病例。

Application Value of CTA in Patients with Acute Complicated Massive Hemoptysis before Interventional Embolization

To evaluate the value of CT angiography(CTA) before interventional embolization in patients with acute complex massive hemoptysis, CTA imaging data of 49 patients with acute complex massive hemoptysis were selected retrospectively. Compared with intraoperative digital subtraction angiography(DSA),it was found that the accuracy rate of vascular diagnosis for criminals was89.33%,and 86.96%for multi-artery anastomosis.The results of CTA and DSA by Kappa test were in good agreement.Receiver operating characteristic curve(ROC)analysis showed that the area under curve(AUC)of CTA in the diagnosis of acute complicated massive hemorrhage criminals was 0.947(95%CI:0.903~0.990,P= 0.000),with sensitivity 89.33% and specificity 100.00%.Follow-up showed that the effective rate of interventional embolization guided by CTA was 91.84%.There was no recurrence of massive hemoptysis in one year after operation.
