human anatomy, the anterior communicating artery is a blood vesselof the brainthat connects the left and right anterior cerebral arteries.
The anterior communicating artery connects the two anterior cerebral arteries across the commencement of the
longitudinal fissure. Sometimes this vessel is wanting, the two arteries joining together to form a single trunk, which afterward divides; or it may be wholly, or partially, divided into two. Its length averages about 4 mm, but varies greatly. It gives off some of the anteromedial ganglionic vessels, but these are principally derived from the anterior cerebral artery.
It is part of the cerebral arterial circle, also known as the
circle of Willis.
Aneurysms of the anterior communicating artery are the most common circle of Willis aneurysm [Beck J, Rohde S, Berkefeld J, Seifert V, Raabe A. Size and location of ruptured and unruptured intracranial aneurysms measured by 3-dimensional rotational angiography. Surg Neurol. 2006 Jan;65(1):18-25; discussion 25-7. PMID 16378842.] and can cause visual field defects such as bitemporal hemianopsia, [Aoki N. Partially thrombosed aneurysm presenting as the sudden onset of bitemporal hemianopsia. Neurosurgery. 1988 Mar;22(3):564-6. PMID 3362325.] psychopathologyand frontal lobepathology. [Johnson MK, O'Connor M, Cantor J. Confabulation, memory deficits, and frontal dysfunction. Brain Cogn. 1997 Jul;34(2):189-206. PMID 9220085.]
