| Abstract text: | The hepatic plexus consists of the efferent fibers from the coeliac plexus to the liver. A rather well known anatomical structure, this plexus, seems to be, at least in some publications, simply described, thus conforming to the Nomica Anatomica. The evidence-based study we performed on human adult specimens allows us to sustain reconsidering the brief descriptions and to define the anterior hepatic plexus, which is a network surrounding the hepatic artery, and the hepatic posterior plexus, which is a nervous radiation of the coeliac ganglion, lying posterior to the portal vein. To the hepatic plexus constitution, contribute the posterior hepatic nerves that appear like 4 – 5 trunks, which give collaterals only in the neighborhood of hepatic hile, where send fine boughs with a parallel trajectory. These nerves are not forming a plexus and are disposed at the posterior of the hepatic pedicle, thus: a retro arterial fillet (posterior of its own hepatic artery); 3 – 4 retro-portal fillets (behind the portal vein); 1 – 2 retro-choledochal fillets. The anterior hepatic plexus is the periarterial plexus, starting from the coeliac region and plexus of the common hepatic artery. This is a net with large holes which is going ascendant around its own hepatic artery (the hepatic artery own plexus) in the hepatic pedicle’s frame and descendant, with the gastro-duodenal plexus artery. |
