左冠状动脉异常起源于肺动脉的临床分析（附5例报告）

目的：回顾分析左冠状动脉异常起源肺动脉（anomalous origin of the left coronary artery from pulmonary artery，ALCAPA）的临床表现和辅助检查，探讨其影像学征象及其原因。方法：回顾分析本院2006年4月至2008年8月共5例经手术明确诊断的ALCAPA的临床及胸片、彩色超声心动图、CT等影像资料。结果：5例心血管造影及1例冠脉CT造影均明确诊断ALCAPA，其中3例左冠主干及其分支均起源于肺动脉，诊断完全型ALcAPA，2例仅左冠分支起源于肺动脉，诊断部分型ALCAPA；所有病例经手术征实。结论：心血管造影目前仍是诊断ALCAPA的金标准，且利用64排螺旋CT进行冠脉CT造影，具有检查时间短，无创伤性，分辨率高，可以后处理等优点。

Clinical Analysis of Anomalous Origin of the Left Coronary Artery from Pulmonary Artery

Objective：To recognize the clinical, EKG, UCG and radiological findings of anomalous origin of the left coronary artery from pulmonary artery （ALCAPA）. Materials： and Methods 5 cases of ALCAPA between 2006 and 2008 were reviewed. All of them were performed with chest films, EKG, UCG, CAG, and one of them was performed with 64 - row MDCT additionally. Results ： 3 eases were completed ALCAPA, 2 cases were partial ALCAPA. Conclusion： ALCAPA must be considered when one＇ s heart was enlarged and inner structure was normal. If normal origin of left coronary artery could not be found on UCG, CAG must be performed. If possible, coronary CT angiography would be better.
