Each posterior communicating artery is situated within the interpeduncular cistern, superolateral to the pituitary gland. [2]: 450 Each are is situated upon the medial surface of the ipsilateral cerebral peduncle [1]: 477 and adjacent to the anterior perforated substance.
Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain. [1]
The posterior cerebral artery (PCA) is one of a pair of cerebral arteries that supply oxygenated blood to the occipital lobe, part of the back of the human brain. The two arteries originate from the distal end of the basilar artery , where it bifurcates into the left and right posterior cerebral arteries.
The right and left posterior cerebral arteries arise from the basilar artery, which is formed by the left and right vertebral arteries. The vertebral arteries arise from the subclavian arteries. The anterior communicating artery connects the two anterior cerebral arteries and could be said to arise from either the left or right side.
Posterior cerebral artery (PCA), which supplies blood to the posterior portion of the brain, including the occipital lobe, thalamus, and midbrain [5] Both the ACA and MCA originate from the cerebral portion of internal carotid artery , while PCA branches from the intersection of the posterior communicating artery and the anterior portion of the ...
Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex.

The Michigan Supreme Court declined to hear an appeal Monday from a former police officer who is charged with killing a 26-year-old Black man during a traffic stop.. Christopher Schurr was fired ...
Middle cerebral artery Middle cerebral artery and its branches (patient has a hypoplastic A1 segment and an absent PCOM, resulting in a purely MCA angio from internal carotid artery injection) The middle cerebral artery divides into four segments, named by the region they supply as opposed to order of branching as the latter can be somewhat ...
