摘　　要：目的探讨电子束CT(EBCT)在共同动脉干(TA)诊断中的应用价值。方法全组共10例TA患者,年龄2个月至24岁。EBCT检查采用美国ImatronC-150型扫描机进行对比剂增强扫描并做出诊断。将同一患者EBCT检查结果和超声心动图(UCG)(10例)、心血管造影(3例)检查结果及手术所见(1例)进行比较分析。结果EBCT对10例TA均做出定性诊断和分型诊断。UCG对9例做出定性诊断,5例与EBCT分型诊断一致。EBCT对TA并发畸形显示优于UCG。3例行心血管造影的患者中,1例造影诊断与EBCT诊断一致,2例分型诊断有误。1例根据EBCT和右心导管检查结果完成手术。结论EBCT作为1种无创检查技术,完全能够完成TA的诊断及分型,结合UCG和必要的右心导管检查的结果,可以指导手术。Objective To evaluate value of electron beam computed tomography (EBCT) in diagnosis of truncus arteriosus (TA). Methods Ten cases of TA with age ranging from 2-month to 24 years were studied. All cases were examined and diagnosed with Imatron C-150 scanner using contrast media. The results of EBCT were analyzed and compared with the results of echocardiography (in 10 cases), cardiovascular angiography (in 3 cases) and surgery findings (in 1 case). Results EBCT yielded qualitative diagnosis and classification in all 10 cases. Echocardiography revealed qualitative diagnosis in 9 cases, however its classification was accordant to EBCT just!in 5 cases. The concomitant abnormalities of TA were found more with EBCT than that with echocardiography. Cardiovascular angiography was performed in 3 cases, yielding inaccurate classification 2 cases. One case of TA was operated just based on the results of echocardiography, EBCT and catheterization. Conclusion As a noninvasive method, EBCT could yield qualitative diagnosis of TA as well as classification. The results of EBCT examination combining echocardiography and catheterization could guide the operations.
