摘　　要：目的总结单一冠状动脉畸形CT血管成像(computed tomography angiography,CTA)的不同类型及其临床特点,为临床治疗提供参考。方法资料来源于上海健康医学院附属周浦医院及上海市浦东新区光明中医院,通过PACS系统回顾性检索而得。检索时间为2014年12月至2022年10月,共有157326例患者接受冠状动脉CTA检查,其中收集到单一冠状动脉畸形46例,统计分析单一冠状动脉畸形的不同分型及相应亚型的CTA与临床表现差异。结果46例单一冠状动脉畸形病例中有Ⅰ型8例(17.39%),Ⅱ型37例(80.44%),Ⅲ型1例(2.17%)。Ⅱ型男性患者及发生心绞痛比例高于Ⅰ型患者,差异有显著性(P<0.01)。结论单一冠状动脉畸形中Ⅰ型患者女性比例较高,男性以Ⅱ型多见。Ⅱ型中LⅡB亚型及RⅡB亚型容易形成压迫性冠状动脉狭窄,更容易出现心绞痛,临床上应早期干预。Objective To analyze the CTA and clinical manifestations of single coronary artery malformation according to its different classification,and to provide suggestions for further clinical treatment strategy.Method The data were obtained from Zhoupu Hospital Affiliated to Shanghai Medical and Health College and Shanghai Pudong New Area Guangming Chinese Traditional Medicine Hospital through retrospective search of PACS system.The retrieval time was from December 2014 to October 2022.A total of 157326 patients received coronary artery CTA,of which 46 patients with single coronary artery malformation were collected,and the differences between different types of single coronary artery malformation and the CTA and clinical manifestations of corresponding sub-types were statistically analyzed.Result There were 8 cases of typeⅠin 46 cases of single coronary artery malformation,accounting for 17.39%,37 cases of typeⅡ,accounting for 80.44%,and 1 case of typeⅢ,accounting for 2.17%.There were significant differences in gender and proportion of angina pectoris between typeⅠand typeⅡ(P<0.05).Conclusion In the case of single coronary artery malformation,the proportion of women in typeⅠpatients is high,and typeⅡis more common in men.In typeⅡ,LⅡB subtype and RⅡB sub-type are easy to form compression stenosis on coronary arteries,and are more prone to angina pectoris,which should be intervened earlier in clinic.
