Abstract:
Anatomy of portal and superior mesenteric vein confluence was investigated in 54 specimens collected from adult cadavers that underwent autopsy at ViÖt §øc Hospital during 1995 - 2000. Results showed that the average length of superior mesenteric vein is 203cm. The confluence of superior mesenteric and portal vein is under common truncal wall in 15/54 cases. 3 veins, including spleen, superior and inferior mesenteric veins meet each other at unique confluent point in 3/54 cases. 46/54 cases have 9 to 14 vein branches that flow to superior mesenteric vein at left wall of mobilized segment. These branches have cluster-like distribution in 4/45 cases. It is not found that the immobilized segment of superior mesenteric vein divided into two or three that cause difficulty for making portal-aortic anastomosis in right wall. 30/54 cases have Descomps trunk that flows to immobilized segment. 38/54 cases have 2-3 extra branches that flows to superior mesenteric vein from head of pancreas at posterior wall of immobilized segment
