64层螺旋CT诊断先天性冠状动脉起源异常的价值

目的：探讨64层螺旋CT冠状动脉造影诊断冠状动脉起源异常的临床价值。材料和方法：回顾性总结2005年12月至2006年12月间1800例64层螺旋CT冠脉造影的结果，统计冠状动脉起源异常的发生率。结果：1800例检查者中发现冠脉起源异常51例，发病率2．8％。包括右冠状动脉变异11例（21．6％）、左冠状动脉变异8例（15．7％）、左右冠均发生变异1例（2％）、单支冠状动脉1例（2％）、分支变异28例（54．9％）。结论：64层螺旋CT是诊断冠状动脉起源异常的安全有效方法，对临床治疗有重要的意义。

Value of 64- Multislice Computed Tomography in the Diagnosis of Coronary Artery Origin Anomalies

Purpose:To assess the value of 64 multislice computed tomography in the diagnosis of pa- tients with congenital coronary artery origin anomalies.Materials and Methods:We conducted a ret- rospective study of 1800 patients who were examined at our department over a period of 1 year with 64- slice CT angiography.Those with anomalous origin of the coronary arteries were selected for further assessment.Results:In 1800 patients,a total of 51 patients anomalous vessels were found(2.8%),in- cluding anomalous origin of the right coronary artery in 11 patients(21.6%),the left coronary artery in 8 patients(15.7%),both the right coronary artery and the left coronary artery in 1 patient(2%),single coronary artery in 1 patient(2%)and anomalous origin of the branch of coronary artery in 28 patients (54.9%).Conclusion:Our study suggest that 64 multislice computed tomography is an excellent nonin- vasive method in the diagnosis of coronary artery origin anomalies,and may play an important role in planning patient treatment.
