2·Objective To discuss the diagnostic and therapeutic experience in superior mesenteric vein thrombosis (MVT).

目的探讨肠系膜上静脉血栓形成(MVT)的诊断与治疗。

3·The segment of the superior mesenteric vein between the two confluences of the gastrocolic vein and ths ileocolic vein is called the surgical trunk.

位于胃结肠静脉和回结肠静脉注入下腔静脉处之间的一段肠系膜上静脉被命名为“外科干”。

4·The diameters and flow volume as well as blood flow rate of splenic vein and superior mesenteric vein were markedly higher in cirrhosis with hemorrhage than those without hemorrhage.

肝硬化出血组脾静脉、肠系膜上静脉直径增宽、流速加快、血流量明显增多。

5·Conclusion: the lower part of the surgical trunk of the superior mesenteric vein is the abouchement of the ileocolic vein and the upper part was the nearest right abouchement from the ileocolic vein.

结论：肠系膜上静脉外科干下端为回结肠静脉汇入点，上端为右侧距回结肠静脉最近的汇入点。

6·The supply artery and it's branches enlargement, blood pool and regurgitant vein enlargement were showed in 8 cases with hemangioma of small intestine by superior mesenteric arteriogram.

表现为小肠管腔狭窄或不规则狭窄，充盈缺损。8例血管瘤小肠血管瘤显示供血动脉及分支增粗，血池，回流静脉增粗。

7·The mesenteric artery was anastomosed to the left cervical transverse artery in 16 cases, to left superior thyroid artery in 2. The mesenteric vein was connected to external jugular vein in 18 cases.

其中2例采用甲状腺上动脉与肠系膜动脉吻合，16例采用颈横动脉与肠系膜动脉吻合，全组18例均采用颈外浅静脉与肠系膜静脉吻合。

8·The hemorrhagic points were at arteria mesenteric superior(3cases), arteria gastric sinistral(1 case), and vein paraumbilicales(1 case), the hemorrhagic points of the other 3 cases were unknown.

出血部位在肠系膜上动脉3例，胃左动脉1例，副脐静脉1例，出血部位不明3例。

9·Qualitative analysis showed that the T1WI was the best sequence for demonstrating the splenic vein and could clearly show the superior mesenteric vessels. The portal vein and the coeliac artery.

定性分析表明，T1WI显示脾静脉最好，且能同时清楚显示肠系膜上血管、门静脉和腹腔动脉。

10·Supine admission Measurement of the left renal vein diameter of the trunk section and wear Rufu aorta and superior mesenteric artery Angle paragraph diameter.

取仰卧位测量其左肾静脉主干段内径及穿入腹主动脉与肠系膜上动脉夹角段内径。
