Abstract

The knowledge about the formation and relations of the portal vein is important for surgeons and radiologists. The variations in the level of formation and the pattern of formation of portal vein might lead to confusions during radiological and surgical procedures. Here we present a rare variation in the formation of the portal vein as found during the cadaveric dissections. The portal vein was formed by the union of splenic vein, superior mesenteric vein and inferior mesenteric veins. The abnormal termination of left gastric vein into superior mesenteric vein before the formation of portal vein was also seen in the same cadaver. Identification of these variations is useful in managing traumatic rupture of the mesentery.

Keywords

Resumo

O conhecimento sobre a formação e as relações da veia porta é importante para cirurgiões e radiologistas. As variações no nível de formação e o padrão de formação da veia porta podem causar confusões durante procedimentos cirúrgicos e radiológicos. Neste relato, apresentamos uma variação na formação da veia porta encontrada durante as dissecções cadavéricas. A veia porta foi formada pela união da veia esplênica, veia mesentérica superior e veias mesentéricas inferiores. A terminação anormal da veia gástrica esquerda na veia mesentérica superior antes da formação da veia porta também foi observada no mesmo cadáver. A identificação dessas variações é útil para tratar a ruptura traumática do mesentério.
