A study of the accessory hepatic vein to segments VI and VII with a morphological reconsideration of the human liver

摘要: The liver is supplied by the common hepatic artery from celiac trunk and portal vein gastrointestine. This double blood supply to produced a complicated structure in liver. For outflow, we can see right, intermediate left veins, irregular veins: accessory veins. These veins drain into inferior vena cava. In this study, studied layout of draining segments 6 7 human livers attempted reconsider vein. Sixty were subjected study. They prepared using forceps trace vessels inside livers. We carefully examined relation between layouts confluence patterns cava also find character standard was studied. found 2.2 one on average our always within area 7, did not surpass boundary. at most five two cases. had its stem dorsal side Different stem, periphery freely distributed with peripheral branches part 7. small usually, but big few When big, became solely drained vein, because (right veins) reach area, any communication As remaining region smaller, right shorter smaller. excluded Therefore, there are different venous networks classified Couinaud. somewhere where reach. would suggest that makes an isolated segment Couinaud’s Classification. might have unique circulation system.
