【摘要】：目的探讨利用Myrian系统构建胰腺周围主要血管的3D结构的方法及其在临床应用中的意义。方法通过GE64层CT采集60例胰腺部位扫描数据,利用Myrian软件系统对胰腺周围动脉血管群、静脉血管群的分布情况进行3D重建,并测量血管长度、夹角、汇入情况等数据。结果腹腔的主要动脉,如腹主动脉、脾动脉、肝总动脉,以及腹腔的部分静脉,如门静脉、脾静脉、肠系膜上静脉的重建率可达100%;门静脉干长度平均(46.37±11.48)mm,其中大于45mm的优势长度占45.54%;胰后干长度为(34.88±9.13)mm,其中大于35mm的优势长度占57.21%。门静脉与脾静脉的夹角为锐角的有17例(占28.33%),为直角的有11例(占18.33%),为钝角的有32例(占53.33%)。肠系膜下静脉的汇入方式为脾静脉的有19例(占31.67%),为肠系膜上静脉的有34例(占56.67%),为脾静脉和肠系膜上静脉交汇点的有7例(占11.67%)。结论 Myrian系统可用于对胰腺周围血管的3D结构重建,而且重建率较高,可用于指导临床手术实施的可行性分析,减少手术过程中因不清楚血管分布情况而导致的出血风险。
[Abstract]:Objective to explore the method of constructing 3D structure of major peripancreatic vessels using Myrian system and its clinical significance. Methods the scanning data of 60 cases of pancreas were collected by GE 64 slice CT. The distribution of peripancreatic artery group and venous vessel group were reconstructed by Myrian software system, and the data of vessel length, angle and confluence were measured. Results the main arteries of abdominal cavity, such as abdominal aorta, splenic artery, common hepatic artery, and partial vein of abdominal cavity, such as portal vein and splenic vein, The average length of portal vein was (46.37 卤11.48) mm, in which the dominant length was greater than 45mm (45.54), and the length of posterior pancreatic trunk was (34.88 卤9.13) mm, in which the superior length was larger than 35mm (57.21) mm. There were 17 cases (28.33%) with acute angle between portal vein and splenic vein, 11 cases (18.33%) with right angle and 32 cases (53.33%) with obtuse angle. There were 19 cases (31.67%) of inferior mesenteric vein, 34 cases (56.67%) of superior mesenteric vein and 7 cases (11.67%) of splenic vein and superior mesenteric vein. Conclusion Myrian system can be used to reconstruct 3D structure of peripancreatic vessels, and the reconstruction rate is high. Myrian system can be used to guide the feasibility analysis of clinical operation and reduce the risk of hemorrhage caused by unclear vascular distribution during operation.
