摘要
前言关于肝内部分的门静脉、国内、外都有比较详细的报导。至于肝外部分的门静脉,国外近年来有Douglass(1950)[1]及Purcell(1951)[2]用解剖的方法进行了观察;Celis(1948)[3]及Dreyer等(1952)[4]首先分别经由脐周围静脉丛和脾脏直接穿刺注入显影剂使脾靜脉和門靜脉显影.
Observations and measurements of the extrahepatic portal vein on 120 specimens arepresented.1.The pattern of the pedicle of the portal vein may be classified into three types:(1)The portal vein is formed by convergence of the splenic and superior mesen-teric veins and the inferior mesenteric vein terminates in the splenic vein in 62 of thespecimens(51.67±4.6%).The distance from the termination of the inferior mesentericto the angle of portal confluence varies from 0.3 to 3.9 cm.(2)The termination of the inferior mesenteric vein is at the angle formed by theunion of the splenic and superior mesenteric veins in 17 of the specimens(14.17±3.3%).(3)The inferior mesenteric vein terminates in the superior mesenteric vein in 41of the specimens(34.17±4.3%).The distance from the termination of the inferiormesenteric to the angle of the portal confluence varies from 0.3 to 2.8 cm.2.The length of the portal trunk varies from 4.5 to 9.2 cm.with 6.75 cm.as anaverage.3.The postmortem diameter of the portal trunk varies from 0.7 to 1.9 cm.with1.25 cm.being the average.4.The point of division of the portal vein into 1eft and right branches is found65.84±4.3%(79 specimens)intrahepatic and 34.16±4.3%(41 specimens)extra-hepatic.5.The topographic relations of the portal vein with the biliary tract and thebranches of the bepatic artery together with some variations are studied and discussed.
