摘　　要：目的以冠状动脉造影为金标准,评价64层螺旋CT冠状动脉成像(64SCTCA)在冠状动脉支架术后随访中的临床价值。方法对33例支架术后患者共57个支架行CT冠状动脉成像,观察冠状动脉支架处是否再狭窄并与冠状动脉造影(CAG)结果对照。结果 64SCTCA检查显示57个支架部位再狭窄8处,与CAG相比误判3处,漏判一处,但两者差别无统计学意义。其敏感度和特异度分别达到了83.3%和94.1%。结论 64SCTCA能够较准确判断冠状动脉支架术后是否发生了再狭窄,可作为支架术后随访的重要手段。Objective To evaluate the accuracy and feasibility of 64-slice spiral computed tomography coronary angiography（64SCTCA） in assess coronary in-stent restenosis in comparison with coronary angiography（CAG）（gold standard）.Methods Thirty-three patients with 57 stents were underwent 64SCTCA to analysis the patency of the stents and the result was compared with that of CAG.Results 64SCTCA demonstrated that restenosis took place in 8 of 57 stents,and,in comparison with CAG,three of which were erroneously identified as restenosis and one of which missed.But the difference of the two methods was no significance.The sensitivity and the specificity were 83.3% and 94.1% respectively.Conclusion 64SCTCA can determine if stenosis occurred in stents of the coronary and is an important method in follow up after stenting.
