Dissecting Aneurysm of the Posterior Cerebral Artery

World Neurosurgery, 2023
Posterior circulation aneurysms are more likely to rupture than those in the anterior circulation but also pose more of a challenge for endovascular treatment or neurosurgical clipping. Aneurysms arising from the posterior cerebral artery are rare; dissecting aneurysms are even rarer. Dissecting posterior cerebral artery aneurysms can be spontaneous or

Posterior cerebral artery stenosis

Annals of Neurology, 1987
AbstractWe analyzed the clinical features of symptomatic posterior cerebral artery (PCA) stenosis in 6 patients selected from 15 patients with angiographically documented PCA atherostenosis occurring during a 7‐year period. Transient ischemic attacks (TIAs) were the major presentation in 5 patients.

Complete duplication of the posterior cerebral artery

Surgical and Radiologic Anatomy, 2023
Variations of the posterior cerebral artery (PCA) are rare, excluding aplasia or hypoplasia of the P1 segment. To the best of our knowledge, there are few reports of complete duplication of the PCA.Herein, we report a case of complete duplication of the PCA diagnosed by 1.5 T magnetic resonance angiography.A 55-year-old woman visited our hospital for ...

Hemiplegia in posterior cerebral artery occlusion

Neurology, 1990
We report 4 patients with hemiplegia due to a posterior cerebral artery occlusion. Associated clinical signs were aphasia, alexia or a neglect syndrome, hemianopia, and hemisensory loss. Hemiplegia was due to infarction in the lateral midbrain. The level of the occlusion in the posterior cerebral artery may be located distal to the junction with the ...

Hemiplegia in posterior cerebral artery strokes

Acta Neurologica Scandinavica, 1993
Hemiplegia is an unusual presenting feature of posterior circulation strokes. We report five cases who presented with hemiplegia and in whom CT scans revealed evidence of infarcts in posterior cerebral artery territory.

Replaced posterior cerebral artery

Surgical and Radiologic Anatomy
Replaced posterior cerebral artery (PCA), defined as a hyperplastic anterior choroidal artery (AChA) supplying all branches of the PCA, is an extremely rare anatomical variation. To the best of our knowledge, there are only a few reports of replaced PCA.Herein, we report a case of replaced PCA diagnosed by digital subtraction angiography.A 76-year-old ...

Aneurysms of the posterior cerebral artery in children

Pediatric Radiology, 1988
Two cases of aneurysms of the posterior cerebral artery, diagnosed by CT and confirmed angiographically, are reported. In the first case, the aneurysm was discovered fortuitously. The second began with intracerebral haemorrhage. A review of the literature is reported.

Fenestrations of the human posterior cerebral artery

Child's Nervous System, 2014
The posterior cerebral artery (PCA), as a paired terminal branch of the basilar artery, runs through four segments (P1 to P4) to the inferior and medial surfaces of the occipital and a part of the temporal lobes. There are many PCA variants in its course.

Anastomoses in the Territory of the Posterior Cerebral Arteries

Cells Tissues Organs, 1986
Anastomoses in the region of the posterior cerebral arteries were found in all of 40 brains examined. Anastomoses were channel-like, plexiform or combined. The former measured from 0.07 mm to 1.1 mm in diameter. They were most often found among the interpeduncular perforating vessels (71.2%), and between the branches of the posterior and anterior ...

Microsurgical anatomy of the posterior cerebral artery

Journal of Neurosurgery, 1978
✓ In order to define the microsurgical anatomy, 50 posterior cerebral arteries (PCA's) were examined using × 3 to × 40 magnification. The PC A was divided into four segments: Pt was the segment proximal to the posterior communicating artery (PCoA); P2 extended from the PCoA to the posterior margin of the midbrain and was subdivided into an equal ...
