摘要
目的 探讨分析多层螺旋CT冠状动脉造影与数字减影血管造影(DSA)诊断经皮冠状动脉介入术(PCI)术后再狭窄中的效果.方法 选择我院收治的78例PCI术患者作为本次研究对象,纳入时间为2021年8月至2023年8月,患者均行多层螺旋CT冠状动脉造影与DSA诊断,以DSA诊断结果为金标准,针对不同诊断方式PCI术后再狭窄情况等展开分析.结果 78例PCI术患者支架共计160枚,经多层螺旋CT冠状动脉造影诊断显示术后出现狭窄30枚(18.8％),未出现狭窄130枚(81.2％),DSA诊断结果显示出现狭窄34枚(21.2％),未出现狭窄126枚(78.8％);PCI术后再狭窄的诊断中,多层螺旋CT冠状动脉造影特异度98.4％,灵敏度82.4％,阳性预测率93.3％,阴性预测率95.4％.结论 多层螺旋CT冠状动脉造影对于PCI术后再狭窄诊断结果同DSA诊断近似,能够较好预测PCI术后再狭窄情况,充分发挥辅助作用,临床将以上2种诊断方法结合应用,不仅可及时发现PCI术后再狭窄情况,而且可为相关治疗工作提供科学依据,同时还可作为筛查冠心病、PCI术后随访工具使用.
Abstract
Objective To explore and analyze the effect of multilayer spiral CT coronary angiography and digital subtraction angiography(DSA)in diagnosing post-percutaneous transluminal coronary intervention(PCI)restenosis.Methods Seventy-eight PCI patients admitted to our hospital were selected as the object of this study from August 2021 to August 2023,who all underwent multilayer spiral CT coronary angiography and DSA diagnosis.With DSA diagnosis as the gold standard,compare the diagnostic value of different diagnostic modalities of post-PCI restenosis situations and so on.Results Seventy-eight PCI patients had 160 stents,thirty stents with stenosis were diagnosed by multilayer spiral CT coronary angiography,accounting for 18.8％,and 130 stents with no stenosis were diagnosed,accounting for 81.2％.Thirty-four stents with stenosis were diagnosed by DSA,accounting for 21.2％,and 126 stents with no stenosis were diagnosed,accounting for 78.8％.In the diagnosis of restenosis after PCI,multilayer spiral CT coronary angiography had a specificity of 98.4％,a sensitivity of 82.4％,a positive prediction rate of 93.3％,and a negative prediction rate of 95.4％.Conclusion Multilayer spiral CT coronary angiography for post-PCI restenosis diagnostic results with DSA diagnostic results can better predict the post-PCI restenosis situation.A clinical combination of the above two diagnostic methods not only can be found promptly post-PCI restenosis,but also for the relevant treatment to provide a scientific basis for the work,and at the same time it can be used as a screening for coronary heart disease and a follow-up tool after PCI.
