ประโยคมือถือ
  • The internal carotid then divides to form the anterior cerebral artery and middle cerebral artery.
  • The medial aspect ( leg areas ) is supplied by branches of the anterior cerebral artery.
  • The anterior communicating artery connects the two anterior cerebral arteries across the commencement of the longitudinal fissure.
  • When the anterior cerebral artery constricts, reining in the response to this increased blood volume, the pain disappears.
  • It gives off some of the anteromedial ganglionic vessels, but these are principally derived from the anterior cerebral artery.
  • The most frequent location for a watershed stroke is the region between the anterior cerebral artery and middle cerebral artery.
  • Anterior cerebral artery syndrome refers to symptoms that follow a stroke occurring in the area normally supplied by one of the arteries.
  • The anterior cerebral artery forms the anterolateral portion of the circle of Willis, while the middle cerebral artery does not contribute to the circle.
  • The patient suffered from a ruptured aneurysm near the anterior cerebral artery, which resulted in the right hand being mirrored by the left hand.
  • Cerebral aneurysms, also known as intracranial or brain aneurysms, occur most commonly in the anterior cerebral artery, which is part of the circle of Willis.
  • 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.
  • 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.
  • 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.
  • 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.
