本文观察的材料为成人尸体84具(男65,女19)。在78例标本中,有3.85％胃左静脉(冠状静脉)缺如,其余的以汇入门静脉为主(60％),其次是汇入脾静脉(30.67％)和门脾静脉夹角处(9.33％)。46例标本中,胃左静脉在网膜囊后方行向右下时,以越过脾动脉前方者(52.17％),或越过肝总动脉的前、后或上方者(43.48％)为主。外科干的下界恒定为回结肠静脉汇入处;上界变化较大:(1)可为Henle氏干,或Henle氏干与其他静脉的合干;(2)可为右结肠静脉或右结肠静脉与其他静脉的合干;(3)也可以是胃网膜右静脉。测量了外科干的长度和中点处的外径。观察了外科干的毗邻。本文所观察的外科干,有90％可进行肠腔静脉端侧分流术。 右结肠静脉与回结肠静脉之间恒定地存在吻合。80％的第1空肠静脉收纳胰和十二指肠升部的静脉血。第1、2空肠静脉之间也有吻合。上述吻合对肠腔静脉端侧分流术,提供了较好的侧支循环通路。
The material observed in this paper is 84 adult male (male 65, female 19). Among the 78 specimens, 3.85% of gastric left venous (coronary vein) were absent. The rest were mainly portal vein (60%), followed by splenic vein (30.67%) and splenic vein at the angle 9.33%). Of the 46 specimens, the left gastric venous line was inferior to the posterior portion of the omental capsule in the front of the splenic artery (52.17%) or the anterior, posterior or superior hepatic artery (43.48%). The lower limit of the surgical dry constant for the entrance of the return of the ileum vein; larger changes in the upper bound: (1) may be Henle’s dry, or Henle’s dry and other venous co-stem; (2) can be the right colon or right colon Venous and other venous co-stem; (3) can also be the right gastric vein. The length of the surgical stem and the outer diameter at the midpoint were measured. Surgical dry adjoining was observed. Surgical trunk observed in this article, 90% of the venous end-shunt can be carried out. There is a constant anastomosis between the right colon vein and the ileocolonic vein. 80% of the first jejunal vein contains the pancreatic and duodenal ascending venous blood. Between the first and second jejunal veins also have anastomosis. The anastomosis on the end of the intestinal venous shunt, provides a better collateral circulation.
