摘要
目的探讨CT冠状动脉成像评价冠状动脉慢性完全闭塞(chronic total occlusion,CTO)病变的价值。方法回顾性分析30例经冠状动脉造影确诊为冠状动脉CTO病变患者的冠状动脉CT血管成像(coronary computed tomography angiography,CCTA)影像资料,分析冠状动脉CTO病变的CCTA特征。结果 30例患者CCTA显示43个冠状动脉闭塞节段,CCTA诊断CTO病变的敏感度为86.04%,特异度为98.94%;冠状动脉CTO病变53.49%位于右冠状动脉,72.09%合并钙化。结论CCTA诊断冠状动脉CTO病变具有较高敏感度及特异度,可显示冠状动脉CTO病变特征。
Objective To evaluate the value of coronary computed tomography angiography （CCTA） to the evaluation of coronary chronic total occlusion （CTO）. Methods The CCTA imaging data were retrospectively analyzed in 30 patients with coronary angiographically confirmed CTO, and the CCTA characteristics of coronary CTO were studied. Results Thirty patients were found 43 coronary artery occlusion segments, the sensitivity of CCTA for the diagnosis of CTO was 86.04%, and the specificity was 98.94%. OCT was mostly located in the right coronary artery （53.49%）, commonly complicated with calcification （72.09%）. Conclusion CCTA has a high sensitivity and specifieity for the diagnosis of CTO, and can show the characteristics of CTO.
