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 pulmonaryartery,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;所有病例经手术证实。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。
OBJECTIVE: To retrospectively analyze the clinical manifestations and auxiliary examinations of anomalous origin of the left coronary artery from pulmonary artery (ALCAPA) and to explore its imaging signs and its causes. Methods: A retrospective analysis of our hospital from April 2006 to August 2008 a total of 5 cases of ALCAPA clinically diagnosed clinically and chest X-ray, color echocardiography, CT and other imaging data. Results: ALCAPA was diagnosed in 5 cases of coronary angiography and 1 case of coronary CT angiography. Three cases of left main coronary artery and its branches originated from the pulmonary artery, the diagnosis of complete ALCAPA, 2 cases of left coronary artery only originated from the pulmonary artery, ALCAPA; all cases confirmed by surgery. Conclusions: Cardiac angiography is still the gold standard for diagnosis of ALCAPA. CT angiography with 64-slice spiral CT has the advantages of short examination time, non-invasiveness, high resolution and post-treatment.
