摘　　要：目的探讨构建胰十二指肠区动脉血管3D可视化模型和研究胰十二指肠区动脉血管的结构特征。方法采用128排螺旋CT对5例新鲜肝标本进行扫描,并进行三维重建。记录螺旋CT影像下胰十二指肠区血管的空间位置关系。结果构建的胰十二指肠区动脉血管三维模型图像清晰,管道饱满,立体空间感强,均能清晰地显示胰十二指肠区动脉的4级以上血管,各级分支血管的形态、走行、分布及各血管间的吻合显影清晰,效果满意。清晰显示胰十二指肠区动脉血管网的构建特点。结论采用聚乙烯醇-氧化铈血管造影术胰十二指肠区动脉血管灌注可构建理想的胰十二指肠区动脉血管网3D可视化模型,为系统研究人胰十二指肠区动脉血管网的形态结构和血供分布提供了血管解剖学基础。Objective To discuss the establishment of 3D digitalization visualization model of vessels net in the artery of pancreas and duodenum region and research structure character of the artery of pancreas and duodenum region.Methods CT was used to examine the anatomic relationship between pancreas and duodenum region and its blood vessel in 5 liver specimens.Results ① The model imaging was clear,with full vessels and strong spacial sense.It precisely displayed more than 4 levels of uterine artery blood vessels,the morphology,distribution,and vascular anastomosis to other vessels were clear and satisfactory.All cases had normal uterine without tumor.② It precisely displayed the construction characters of vessel net in the artery of pancreas and duodenum region： it was separated into bladder branch,ureter branch,ascending branch,descending branch and other branches from the stem;The thicker upward one was distributed upwards along lateral margin of uterine wall,and at cornua uteri,it was separated again into uterine fundus branch,tubal branch and ovarian branch;While the thinner downward one was distributed in cervix uteri and superior segment of vagina,with less in vagina vessel;Uterine artery was intersected with ovarian artery via its ovarian branch;The blood-supply of uterine artery had obvious homolateral preference.But a few communicating branchs of bilateral uterine artery still could be found in the media axis of uterine.Conclusion Perfusion of the artery of pancreas and duodenum region by angiography with polyvinyl is satisfactory method for alcohol-ceria establishment of 3D digitalization visualization model.It provides vessel anatomy evidence for systematic study on vessel net morphology and distribution of the artery of pancreas and duodenum region.
