摘要
目的:探讨64螺旋CT冠脉成像在诊断冠心病及经皮冠状动脉介入治疗(PCI)后评估中的应用价值。方法:回顾性分析2016年5月-2018年5月我院收治的60例疑似冠心病患者病例资料,所有患者均行CT冠脉成像(CTA)检查,并将冠状动脉造影作为"金标准",分析CTA诊断结果。结果:在60例疑似冠心病患者中,冠状动脉造影检出阳性32例,阴性28例,CTA诊断敏感性、特异度、准确度分别为90.63%、82.14%、85.00%;32例患者行PCI术治疗共植入冠状动脉支架44枚,其中术后冠脉造影显示非狭窄35枚,再狭窄9枚,CAT显示非狭窄35枚,再狭窄7枚,有2枚因图像模糊无法进行评价,得出CTA诊断冠状支架再狭窄敏感性、特异度、准确度分别为77.78%、100%、95.45%。结论:64螺旋CT冠脉成像技术具有便捷、无创等优势,其在冠心病诊断中具有较高应用价值且可较好的判断PCI术后支架狭窄情况。
Objective： To investigate the application value of 64-slice spiral CT angiography（CTA） in diagnosis of coronary heart disease（CHD） and postoperative evaluation of percutaneous coronary intervention（PCI）. Methods： The case data of 60 suspected CHD in the hospital from May 2016 to May 2018 were retrospectively analyzed. All the patients were given CTA examination. The coronary arteriography was taken as the gold standard,and the diagnostic results of CTA was analyzed. Results： 32 positive cases and 28 negative cases were detected by coronary arteriography in 60 cases of suspected CHD,and the diagnostic sensitivity,specificity,accuracy of CTA were 90. 63%,82. 14%,85. 00%; There were 44 coronary stent implantation in 32 patients with PCI,35 cases of non-stenosis and 9 cases of restenosis showed by postoperative coronary arteriography,35 cases of non-stenosis and 7 cases of restenosis showed by CTA,and 2 cases could not be evaluated because of image blurring,the diagnostic sensitivity,specificity,accuracy of CTA in coronary stent restenosis were77. 78%,100%,95. 45%. Conclusion： 64-slice spiral CTA is convenient and noninvasive,it has higher application value in diagnosis of CHD,and it can better judge the stent restenosis after PCI.
