Thrombi at the split of the internal carotid artery in the neck may cause watershed infarcts between the territories of the anterior cerebral artery and the middle cerebral artery.

The disease causes constrictions primarily in the internal carotid artery, and often extends to the middle and anterior cerebral arteries, branches of the internal carotid artery inside the skull.
13.
Other cases include duplication of the MCA at the internal carotid artery ( ICA ) or an accessory MCA ( AccMCA ) which arise not from the ICA but as a branch from the anterior cerebral artery.

His name is also lent to " Heubner's artery ", a cerebral artery that typically originates from the junction of the A 1 and A 2 segments of the anterior cerebral artery ( ACA ).

Goldberg and Bloom described a woman who suffered a large cerebral infarction of the medial surface of the left frontal lobe in the territory of the left anterior cerebral artery which left her with the frontal variant of the alien hand involving the right hand.
16.
The anterior optic nerve is supplied by the short posterior ciliary artery and choroidal circulation, while the retrobulbar optic nerve is supplied intraorbitally by a pial plexus, which arises from the ophthalmic artery, internal carotid artery, anterior cerebral artery, and anterior communicating arteries.
17.
These approaches are based on general experience, and the only randomized controlled trial directly comparing the different modalities was performed in relatively well patients with small ( less than 10 mm ) aneurysms of the anterior cerebral artery and anterior communicating artery ( together the " anterior circulation " ), who constitute about 20 percent of all patients with aneurysmal SAH . This trial, the " International Subarachnoid Aneurysm Trial " ( ISAT ), showed that in this group the likelihood of death or being dependent on others for activities of daily living was reduced ( 7.4 percent absolute risk reduction, 23.5 percent relative risk reduction ) if endovascular coiling was used as opposed to surgery.
