摘　　要：目的:探讨双源CT(DSCT)在先天性心脏病肺静脉异常连接(APVC)中的诊断价值。方法:35例患者中男25例,女12例。22例经手术证实,对DSCT诊断APVC类型进行分析。结果:双源CT诊断APVC的符合率为100%(22/22),对伴发畸形的诊断符合率为90.9%(20/22)。DSCT诊断完全型APVC 20例57.1%(20/35),最常见异常连接血管为上腔静脉48.9%(23/47)、垂直静脉42.6%(20/47),多数存在伴发畸形95%(19/20),房间隔缺损最常见52.6%(10/19)。DSCT诊断部分型APVC 42.9%(15/35),最常见异常连接为右肺静脉连接至右心房占51.6%(16/31),多数存在伴发畸形86.7%(13/15),房间隔缺损最常见46.2%(6/13)。结论:DSCT可以满足APVC的诊断。Objective：To evaluate the diagnostic value of dual source computed tomography（DSCT） on congenital heart disease（CHD） of anomalous pulmonary venous connection（APVC）,and analyse the types of APVC in this group.Methods：Thirty five patients（25 men,12 women,mean age 9.4±7.6 years） were analyzed.The results of DSCT on 22 cases were compared with surgical findings.The types of APVC were diagnosed and analyzed based upon DSCT images.Results：The results of DSCT was 100%（22/22） consistent with that of surgical findings.Associated malformations of APVC diagnosed by DSCT were 90.9%（20/22） consistent with the surgery.Total anomalous pulmonary venous connection（TAPVC） were in 20 patients（57.1%,20/35）.The most common anomalous connecting veins were drained to the superior vena cava（48.9%,23/47） and to the vertical vein（42.6%,20/47）.Associated malformations were found in 95%（19/20） patients,most of which were atrial septal defect（ASD）（52.6%,10/19）.There were 42.9%（15/35） patients diagnosed as partial anomalous pulmonary venous connection（PAPVC）,the most common anomalous veins were the right pulmonary veins connecting to the right atrium（51.6%,16/31）.Associated malformations were about 86.7%（13/15）,most of which were ASD（46.2%,6/13）.Conclusion：DSCT was able to meet the requirement for the diagnosis of APVC.
