Abstract：Objective To observe the anatomical variations of Celiacomesenteric trunk(CMT)through dual-source CT enhanced scanning,summarize its anatomical features and complications,and provide guidance for clinical practice and surgery.Methods The imaging data of 107 patients with CMT diagnosed by CT enhanced scanning were retrospectively an-alyzed.Maximum intensity projection(MIP),multiplane reconstruction(MPR)and volume rendering(VR)images were recon-structed.The length and diameter of the common trunk of CMT were measured.The origin of the left gastric artery and com-plications were observed.The differences in anatomy and complications among different types of CMT were compared.Re-sults Among the 107 cases of CMT,69 cases(64.49％)were long type and 38 cases(35.51％)were short type;37 cases(34.58％)were type Ⅰ,19 cases(17.76％)were type Ⅱ,40 cases(37.38％)were type Ⅲ,and 11 cases(10.28％)were typeⅣ.The diameter of the common trunk of long type CMT was(8.92±1.66)mm,and that of short type CMT was(10.88±1.65)mm.The difference was statistically significant(t/P=5.860/＜0.001).The differences in subtype distribution,combined with other branch variations,combined vascular lesions,and combined malrotation of the midgut between long type and short type CMT were all statistically significant(x2/P=38.458/＜0.001,4.955/0.026,5.608/0.018,7.089/0.008).Conclusion The anatomical features and imaging manifestations of different types of CMT are different.Dual-source CT enhanced scanning combined with post-processing techniques can provide three-dimensional stereoscopic visualization images,which can help clinical practice and necessary surgical treatment.
