28 maj 2024 · The anterior cerebral artery (ACA), along with the middle cerebral artery (MCA) forms at the termination of the internal carotid artery (ICA). It is the smaller of the two and arches anteromedially to pass anterior to the genu of the corpus callosum, dividing as it does so into its two major branches: the pericallosal and callosomarginal arteries.
7 cze 2024 · The middle cerebral artery (MCA) is one of the three major paired arteries that supply blood to the brain. The MCA arises from the internal carotid artery as the larger of the two main terminal branches (the other being the anterior cerebral artery), coursing laterally into the lateral sulcus where it branches to perfuse the cerebral cortex.
A detailed understanding of normal and variant cerebral arterial anatomy is important to understanding common cerebrovascular diseases, such as ischemic stroke, steno-occlusive disease, cerebral aneurysms, cerebral arteriovenous malformations, and pial and dural arteriovenous fistulae.

The anterior cerebral artery (a. cerebri anterior) arises from the internal carotid, at the medial extremity of the lateral cerebral fissure. It passes forward and medialward across the anterior perforated substance, above the optic nerve, to the commencement of the longitudinal fissure.
30 paź 2023 · Being located in the anterior and medial aspects of the interhemispheric fissure, the anterior cerebral artery supplies a large portion of the medial cerebral hemispheric surfaces namely the corpus callosum, frontal, parietal, and cingulate cortex.
The anterior cerebral artery (ACA) is one of the most important arteries of the brain and in particular of the telencephalon [1, 2]. The ACA is also one of the most studied cerebral arteries since it is a common location for intracranial aneurysms .
