目的通过64层螺旋CT(MSCT)和冠状动脉造影(CAG)影像学资料对照研究,探讨64层MSCT冠状动脉成像(CTA)评价老年冠心病(CAD)患者支架内再狭窄(RSI)的临床意义.方法 57例支架置入术后老年CAD患者(共97枚支架)先后行CAG和64层MSCTA检查.结果 64层MSCT诊断支架内再狭窄的敏感性、特异性、阳性预测值、阴性预测值分别为:77.8％、90.0％、75.0％和91.3％.64层MSCT对直径≥3.0 mm支架再狭窄检出的阳性预测值、特异性、敏感性均优于直径＜3.0mm支架.结论 64层MSCT同样可作为老年CAD患者支架内再狭窄安全、有效的筛查工具.

[Objective] By comparing the images of 64-slice multidetector computed tomography (MDCT)and selective coronary angiography(CAG),to investigate the clinical significance of 64-Slice MDCT angiography on coronary in-stent restenosis in elderly patients.[Methods] The study population consisted of 97 stents implanted in coronary arteries of 57 elderly patients who underwent selective coronary angiography preceded by 64-slice MDCT.[Results] The sensitivity,specificity,positive and negative predictive value,accuracy of 64-slice MDCT diagnose in-stent restenosis were 77.8％,90.0％,75.0％ and 91.3％.The detection with 64-slice MDCT in-stent restenosis of positive predictive value,specificity and sensitivity of diameter ≥ 3.0 mm stents were better than that of the diameter ＜ 3.0 mm stents.[Conclusions] 64-slice MDCT is a safe,valid method for screening and diagnosing of in-stent restenosis in elderly patients with coronary artery disease.
