摘要
目的:探讨利用管道铸型标本CT扫描法对肝门静脉系统三维重建的技术方法,为腹腔镜肝切除手术提供可靠的解剖学依据。方法:采用非肝胆疾病死亡成人新鲜标本10例,经肝门静脉注入氧化铅与明胶混悬液,64层CT连续扫描,利用CT自带软件进行三维重建。结果:横断面原始图像及其三维图像重建均达到满意的效果,可清晰显示5级以上门静脉分支,重建后的模型可以任意三维旋转。结论:管道铸型标本CT扫描法是肝门静脉系进行三维重建的一种有效技术方法,对腹腔镜肝外科术前的计划制定和术中操作具有临床意义。
Objective： To explore the technique and method of three-dimensional reconstruction of hepatic portal vein by CT scan after cast mould, and provide anatomic basis for laparoscopic hepatectomy. Methods： 10 dead adults without hepatic disease were injected lead oxide-gelatine mixture via hepatic portal vein and successive scanning was done by 64-slice CT. Three-dimensional reconstruction of hepatic portal vein were made by CT software. Results： Original cross-sectional images and three-dimensional reconstruction image had satisfied result. Three-dimensional reconstruction models showed clearly higher than five grades branches of portal veins, and the model could rotate in every direction. Conclusion： Cast mould of CT scan is an effective means for three-dimensional reconstruction of hepatic portal vein, which services pre-surgery plan and operation of laparoscopic hepatectomy
