The vagus trunk, anterior (anterior vagus trunk) is the largest part of the vagus trunk, passing in front from the bifurcation of the common carotid artery to its entry into the sternal bulb.
The anterior wall of the internal carotid canal is the main site of compact development of the vagal trunks, where complex anomalies often occur. In particular, the anterior arch - the superior and inferior portions of the anterior wall and the area of the opening of the sella turcica between them - are the most commonly affected areas after the common fasciculus fissure. The passage of the shaft along the anterior wall is most susceptible to the influence of blood vessels, so the likelihood of an anoma
