摘　　要：目的探讨肺静脉的多层螺旋CT解剖分型。方法120例应用多层螺旋CT行冠状动脉CTA检查,对原始横断面图像进行容积重建(VR)和多平面重建(MPR)。按照肺静脉开口数目、肺静脉数目、肺静脉共同开口及副肺静脉出现情况对肺静脉进行分型,统计各型的出现率。对肺静脉共同开口、副肺静脉出现率的性别差异进行统计学分析。结果本组人群中,肺静脉共同开口的出现率为22.5%,副肺静脉的出现率为15.8%,均无性别差异。肺静脉可分为4型,其中标准型最常见,出现率为62.5%,肺静脉共同开口型为21.7%,副肺静脉型为15.0%,混合变异型为0.8%。结论多层螺旋CT对肺静脉的解剖观察,可为临床提供解剖信息。Objectlve To study the multi - slice spiral CT anatomy of pulmonary veins. Methods After accomplishing the scanning of coronary CT angiography in 120 cases with multi - slice spiral CT,the volume rendering and multi - planner reconstruction based on the origi- nal transverse images were performed. The pulmonary, veins style according to the number of pulmonary - atrium ostium, pulmonary vein, common ostium and additional pulmonary vein were classified. The difference of sex in presence of the common ostium and additional pulmonary vein was analyzed statistically. Results The incidence of the common ostium and additional pulmonary vein was 22.5% and 15.8% , respectively, there was no difference in sex. The pulmonary veins included 4 types ： standard type （ 62.5% ） , common ostium type （ 21.7% ） , additional pulmonary vein type （ 15.0% ） , mixed variation type （0.8%）. Conclusion Multi - slice spiral CT can accomplish the observation of pulmonary vein,which can provide anatomic informations for clinic.
