Fetal posterior cerebral artery infarction due to carotid dissection: a case report [PDF]

Journal of Medical Case Reports
Background Fetal posterior cerebral artery is an anatomical variant that occurs in 23–29% of the population. In this variant, posterior circulation, especially to the occipital lobe and mesencephalon, is provided by the posterior communicating artery ...

The Fetal Type of Posterior Cerebral Artery

Medicina (Lithuania), 2023
Background and Objectives: Anatomical variations of the arterial circle of Willis (cW) are common. A posterior cerebral artery (PCA) fed mostly or exclusively from the internal carotid artery is a fetal PCA (FPCA), partial (p-FPCA), or full/complete (f-FPCA), respectively.

Posterior cerebral artery ischemic stroke in a patient with hypoplastic P1 segment of the posterior cerebral artery

Nigerian Journal of Medicine, 2020
Posterior circulation stroke usually presents with clinical challenges, and symptoms may include blindness. Hypoplastic or atretic cerebral artery may be a risk factor for future ischemic stroke.

Bilateral vertebral artery dissection extending to the left posterior cerebral artery: A case report

Radiology Case Reports, 2023
Intracranial artery dissection accounts for a small percentage (1%-2%) of all ischemic strokes. Vertebral artery dissection sometimes extends to the basilar artery but very rarely to the posterior cerebral artery.

Association between symptomatic intracranial atherosclerotic disease and the integrity of the circle of Willis [PDF]

Journal of Integrative Neuroscience, 2022
The relationship between the severity of intracranial atherosclerotic disease and the circle of Willis integrity is unclear. In this brief report, we investigate the associations between symptomatic intracranial atherosclerotic disease and the ...

Dissection of the Posterior Cerebral Arteries [PDF]

Archives of Neurology, 2005
Mostreportedarterialdissectionsinvolvethecarotidandvertebralarteriesintheneck. Within the intracranial arteries, dissections most often involve the vertebral and basilar arteries. 1 Intracranial carotid and middle cerebral artery dissections occur much more rarely and seem to develop in younger individuals compared with patients who develop posterior ...
