摘要
目的:研究肠系膜上动脉(SMA)CT数据三维重建方法及相关解剖。方法:搜集140例患者64排螺旋CT腹部增强扫描数据,采用Mimics 10.01软件进行SMA三维重建,观察、测量3D模型中SMA的相关解剖学指标。结果:SMA 3D模型真实反映了其形态学结构,效果逼真,发现变异肝右动脉或肝总动脉来源于SMA者占9.3%(13例)。SMA与腹主动脉的夹角为(62.3±18.6)°;在左肾静脉水平,SMA与腹主动脉的距离为(1.2±0.5)cm。结论:SMA 3D模型能很好显示其解剖学特征,术前可提供患者的个体化信息,将其运用于临床具有重要意义。
Objective： To study the three-dimensional reconstruction methods and correlated anatomy of superior mesenteric artery （SMA） using spiral CT data. Methods： Abdominal enhanced CT data from 140 patients were collected in this investigation. Data was used for three-dimensional reconstruction by Mimics software, and then anatomic index of SMA was observed and measured on each 3D model. Results： The three-dimensional model displayed vividly anatomic structures of SMA. 13 cases （9.3%） had abnormal right hepatic artery or common hepatic artery which originated from SMA. The average angle of SMA and abdominal aorta was about （62.3±18.6） °. At the level of left renal vein, the average distance between SMA and abdominal aorta was about （1.2±0.5） cm. Conclusions： The 3D reconstruction can clearly visualize anatomical features of SMA. It provides individualization information of patients preoperatively, which is significant in clinic.
