Abstract

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.
