Eighty-five corrosion casts of human portal veins were studied. The following observations were made: (1) In 88% of the cases, the portal vein divided into right and left branches, and in 12% of the cases, it divided into the left branch of the portal vein and anterior and posterior segmental n:veins; (2) Anterior and posterior segmental veins were branches of the right branch of the portal vein in 88% of the cases and arose directly from the portal trunk in 12% of the cases. In all cases, the anterior and posterior segmental veins in turn divided into superior and inferior area veins. (3) The left branch of the portal vein underwent a sharp kink leading into two parts: pars transversa nad pars umbilicalis. (4) The lateral superior area vein either sprang from the left side of the kink (69%), or from pars transversa near the kink (16%), or from the left side of pars umbilicalis near the kink (14%). The lateral inferior area vein arose from the left side of pars umbilicalis in all cases. (5) The medical segmental veins originated from the right side of pars umbilicalis. The number of branches varied from two to four. Further division of these into area branches were not fixed. (6) The right portion of the caudate lobe received portal blood either from the pars transversa (68%), or from the right branch of portal trunk (14%), or from the portal trunk (18%). The left portion of the caudate lobe received portal blood always from the pars transversa of the left trunk. (7) The branches to the caudate process arose from right branch of the portal vein in the majority of cases (72%). In the rest of the cases, these arose either from portal trunk (16% cases) or from pars transversa of the left trunk (12% cases).
对85个腐蚀铸型的人体门静脉进行了研究。得出以下观察结果：(1)88%的病例中，门静脉分为左右分支，12%的病例中，门静脉分为门静脉左支及前后段静脉；(2)88%的病例中，前后段静脉是门静脉右支的分支，12%的病例中，它们直接起自门静脉主干。在所有病例中，前后段静脉又依次分为上下区域静脉。(3)门静脉左支出现急剧弯曲，分为两部分：横部和脐部。(4)外侧上区域静脉要么起自弯曲处左侧(69%)，要么起自弯曲处附近的横部(16%)，要么起自弯曲处附近脐部左侧(14%)。外侧下区域静脉在所有病例中均起自脐部左侧。(5)内侧段静脉起自脐部右侧。分支数量从2到4不等。这些分支进一步分为区域分支的情况并不固定。(6)尾状叶右侧接受的门静脉血要么来自横部(68%)，要么来自门静脉主干右支(14%)，要么来自门静脉主干(18%)。尾状叶左侧接受的门静脉血总是来自左主干的横部。(7)多数病例(72%)中，至尾状突的分支起自门静脉右支。其余病例中，这些分支要么起自门静脉主干(16%的病例)，要么起自左主干的横部(12%的病例)。
