目的探讨16层螺旋CT评价冠状动脉支架内再狭窄的应用价值。方法对24例冠状动脉支架术后患者行心电门控16层螺旋CT冠状动脉成像,以选择性冠状动脉造影结果为对照,分析16层螺旋CT冠状动脉成像对诊断冠状动脉支架内再狭窄的应用价值。结果16层螺旋CT冠状动脉成像诊断冠状动脉支架内再狭窄≥50%的敏感度、特异度、阳性预测值和阴性预测值分别为100%、81%、58%、100%。结论16层螺旋CT冠状动脉成像对冠状动脉支架术后患者的随访有重要价值。
Objective To evaluate the value of 16-slice spiral CT in the evaluation of coronary stent restenosis. Methods Twenty-four patients underwent coronary artery stenting underwent coronary angiography with 16-slice spiral CT coronary angiography. The selective coronary angiography was used as a control. The 16-slice spiral CT coronary angiography was performed to diagnose coronary stent restenosis Value. Results The sensitivity, specificity, positive predictive value and negative predictive value of 16-slice CT coronary angiography in the diagnosis of coronary stent restenosis were 100%, 81%, 58% and 100% respectively. Conclusion 16-slice spiral CT coronary angiography has important value in the follow-up of patients after coronary stenting.
