Anatomical terms of neuroanatomy [edit on Wikidata]

The hepatic branches of anterior vagal trunk are branches of the anterior vagal trunk that provide parasympathetic innervation the liver,^[1]^[2]^: 499 and gallbladder.^[2]^: 266 Each anterior vagal trunk (it may be doubled or tripled) issues 1-2 hepatic branches which pass through the superior part of the omentum minus to reach and join the hepatic (nervous) plexus^[2]^{: 250–252} before proceeding to the porta hepatis.^[2]^: 262 The anterior vagal trunk is the main source of parasymathetic afferents for the hepatic plexus.^[3]

Clinical significance

Selective vagotomy of the anterior vagal trunk can be performed distal to the hepatic branch (in conjunction with sectioning the posterior vagal trunk distal to its coeliac branches) to curb gastric secretion, however, this often results in gastric stasis (to avoid this complication, a highly selective vagotomy that sections only branches to the gastric fundus and body may be performed instead).^[2]^: 252
