摘要
目的探讨双源CT(DSCT)在冠状动脉支架狭窄评估中的应用价值。方法选取2014年9月至2018年3月期间达州市中西医结合医院所收治冠心病行经皮冠状动脉介入治疗患者84例,共计植入160枚支架。在术后12个月时分别采用DSCT和冠状动脉造影检查(CAG),对冠状动脉支架的通畅情况进行评估分析。结果 DSCT对于冠状动脉支架狭窄的诊断敏感率为77.78%,特异度为99.36%,诊断准确率为98.13%;本次研究中,DSCT与CAG对于84例冠心病行介入治疗患者冠状动脉支架内再狭窄检出率并无明显差异(P>0.05);DSCT与超声心动图对于84例患者的LVEF、SV、EDV、ESV检查结果均无明显差异(P>0.05)。结论双源CT冠状动脉成像作为无创性检查方法,可有效对冠心病介入治疗患者冠状动脉支架内狭窄程度进行评估,其准确性同冠状动脉造影检查相当。
Objective To explore the value of dual-source CT(DSCT) in the evaluation of coronary stent stenosis.Methods A total of 84 patients with percutaneous coronary intervention for coronary heart disease were enrolled in our hospital from September 2014 to March 2018.A total of 160 stents were implanted.DSCT and coronary angiography (CAG) were used to evaluate the patency of coronary stents at 12 months postoperatively.Results The diagnostic sensitivity of DSCT for coronary stent stenosis was 77.78%,the specificity was 99.36%,and the diagnostic accuracy was 98.13%.In this study,DSCT and CAG were used to treat coronary artery in-stent restenosis in 84 patients with coronary artery disease.There was no significant difference in the detection rate (P>0.05).There was no significant difference between the DSCT and echocardiography in LVEF,SV,EDV and ESV in 84 patients (P>0.05).Conclusion As a noninvasive method,dual source CT coronary angiography can effectively evaluate the degree of coronary artery stent stenosis in patients with coronary intervention,and its accuracy is similar to that of coronary angiography.
