冠状动脉起源异常的双源CT冠状动脉成像

Imaging of coronary artery origin anomalies by dual-source computed tomography angiography

目的评估双源CT对冠状动脉起源异常的诊断价值。方法回顾性分析双源CT冠状动脉成像5153例临床资料,分析冠状动脉起源异常的CT特征。结果 5153例患者中,检出冠状动脉起源异常共141例(2.74%),其中主干起源异常102例(1.98%),分支起源异常39例(0.76%)。结论双源CT能够准确地显示冠状动脉起源异常及走行,为临床制定诊疗方案提供参考。

Aim To evaluate the diagnostic value of dual-source computed tomography in detecting coronary artery anomalies.Methods Clinical data of 5153 patients who underwent coronary CTA were retrospectively analyzed to determine the CT features of anomalous origin of coronary artery.Results In consecutive 5153 patients,141 cases with anomalies origin were identified （2.74%）,including 102 cases with trunk anomalous origin （1.98%）,39 cases of anomalous branches （0.76%）.Conclusion Dual-source CT could accurately display the anomalous origin of the coronary and direction,provide a reference for clinical diagnosis and treatment.
