The anterior vagal trunk is one of the two divisions (the other being the posterior vagal trunk) into which the vagus nerve splits as it passes through the esophageal hiatus to enter the abdominal cavity. [1] The anterior and posterior vagal trunks represent the inferior continuation of the esophageal nervous plexus inferior to the diaphragm. [2]

The anterior vagal trunk is a mixed nerve that conveys visceral sensory and parasympathetic fibers. It supplies the abdominal portion of the esophagus, cardia, lesser curvature, and superior portion of the anterior surface of the stomach.

2023年8月8日 · The vagus nerve splits into two trunks: the anterior and posterior vagal trunks. The anterior trunk, which receives significant contributions from the left vagus nerve more so than the right, branches into: a hepatic branch, which supplies the liver, gallbladder, and biliary apparatus; a celiac branch, which contributes parasympathetic fibers ...

Anterior vagal trunk refers to the continuation of left vagus nerve as it follows the esophagus through the esophageal hiatus of the diaphragm to enter into the abdominal cavity. Similarly, the posterior vagal trunk is a continuation of the right vagus nerve.

2025年1月6日 · In the thorax, the right vagus nerve forms the posterior vagal trunk, and the left forms the anterior vagal trunk. Branches from the vagal trunks contribute to the formation of the oesophageal plexus, which innervates the smooth muscle of the oesophagus.

The anterior gastric branches of the anterior vagal trunk run from the lower anterior esophageal region, along the cardia, and over the anterior aspect of the lesser curvature of the stomach. They branch to supply the anterior cardia, fundus, and body of the stomach.

The anterior vagal trunk refers to a nerve structure that is at risk of damage during certain surgical procedures. It is important to identify and preserve this structure as it serves as a landmark for performing specific surgical techniques.
