目的探讨双源CT冠状动脉成像诊断冠状动脉起源异常的价值。方法对2 356例成人冠状动脉双源CT血管成像资料进行回顾性分析、总结。结果 2 356例冠状动脉CTA中,检查出冠状动脉起源异常31例,检出率为1.31%,其中冠状动脉开口水平变异9例,两支冠状动脉开口于左冠状窦5例,两支冠状动脉开口于右冠状窦8例,前降支起源于右窦1例,左回旋支起源于右窦2例,前降支及回旋支独立开口于左冠状窦2例,单一冠脉2例(均为单一右冠),左回旋支闭锁2例。结论双源CT冠状动脉成像可以清晰显示冠状动脉起源及走行,是一种良好的无创性的诊断冠状动脉起源异常的可靠方法。
Objective To investigate the value of dual-source CT coronary angiography in diagnosis of coronary artery anomalies. Methods The data of 2 356 coronary angiography double coronary CT angiography were retrospectively analyzed and summarized. Results Among 2 356 coronary artery CTAs, 31 cases of abnormalities of coronary artery were detected, the detection rate was 1.31%. There were 9 cases of coronary artery ostial variation, 5 cases of two coronary arteries in the left coronary sinus and two coronary arteries The anterior descending coronary artery originated from the right sinus in 2 cases, the left circumflex artery originated in 2 cases, the anterior descending branch and the circumflex artery opened in the left coronary sinus in 2 cases and the single coronary artery in 2 cases (both As a single right crown), left circumflex artery occlusion in 2 cases. Conclusion Dual-source CT coronary angiography can clearly show the origin and course of coronary artery. It is a good and non-invasive reliable method to diagnose the origin of coronary artery.
