To identify the veins draining from the pancreatic tail to the lienal vein and its possible relationship with the loss of the distal splenorenal shunt selectivity.
Thirty eight human blocks including stomach, duodenum, spleen, colon and pancreas, removed from fresh corpses, were studied with the replenish and corrosion technique, using vinilic resin and posterior corrosion of the organic tissue with commercial hydrochloric acid, in order to study the lienal vein and its tributaries.
The number of veins flowing directly to the splenic vein varied from seven to twenty two (14.52 + or - 3.53). Pancreatic branches of the pancreatic tail flowing to the segmentary veins of the spleen were found in 25 of the anatomical pieces studied (65.79%). These branches varied from one to four, predominating one branch (60%) and two branches (24%).
In 65.79% of the anatomical pieces studied, the veins of the pancreatic tail flowed in segmentary branches of the splenic vein. These branches could be responsible for the loss of distal splenorenal shunt selectivity. The complete disconnection of the pancreatic tail could increase the selectivity in this procedure.
确定从胰尾引流至脾静脉的静脉及其与远端脾肾分流术选择性丧失的可能关系。
采用灌注和腐蚀技术,使用乙烯基树脂并随后用市售盐酸对新鲜尸体取下的38个包含胃、十二指肠、脾、结肠和胰腺的人体标本进行研究,以研究脾静脉及其分支。
直接流入脾静脉的静脉数量从7条到22条不等(14.52±3.53)。在所研究的25个解剖标本(65.79%)中发现胰尾的胰腺分支流入脾的节段性静脉。这些分支从1条到4条不等,以1条分支(60%)和2条分支(24%)为主。
在所研究的65.79%的解剖标本中,胰尾的静脉流入脾静脉的节段性分支。这些分支可能是远端脾肾分流术选择性丧失的原因。胰尾的完全离断可能会增加该手术的选择性。
