2024年9月29日 · The posterior cerebral arteries are the terminal branches of the basilar artery and supply the occipital lobes and posteromedial temporal lobes. The posterior cerebral artery is divided into four (or sometimes five) segments 8,11.

2024年6月20日 · A fetal (origin of the) posterior cerebral artery (fetal PCA), sometimes also referred to less accurately as fetal (origin of the) posterior communicating artery (fetal PCom), is a common variant in the posterior cerebral circulation. Fetal PCAs occur in …

2023年4月15日 · Posterior cerebral artery (PCA) infarcts arise, as the name says, from occlusion of the posterior cerebral artery. It is a type of posterior circulation infarction. Posterior cerebral artery strokes are believed to comprise approximately 5-10% of ischemic strokes 6.

Fetal-type posterior cerebral artery (FTP) is a common anatomic variation that is closely associated with intracranial aneurysm. In the present study, multislice computed tomography angiography (CTA) was performed to assess whether FTP is a …

The duplication of the posterior cerebral artery (PCA) is an exceedingly rare anatomical variant. Review of the literature yielded only 1 report with digitally subtracted angiographic exhibition of the variant anatomy . Here, we present a case demonstrating the appearance of a duplicated PCA and provide an explanation of its true representation.

An uncommon cause of cerebral ischemia in the territory of the posterior cerebral artery (PCA) is the combination of a fetal origin of the PCA and atherosclerotic disease in the internal carotid artery. This study compared the accuracy of CTA with DSA in the assessment of a …

This study assessed the frequency of a fetal origin of the PCA in patients with a TIA or infarct in the territory of the PCA with 16-multidetector-row CT angiography (CTA). Methods: 82 patients (52 male; mean age = 64; range 19 to 90 years) with isolated homonymous hemianopia and/or a PCA infarct underwent CTA of the carotid artery and circle ...

Diagnostic estimates of CTA in predicting fetal PCA in patients with posterior communicating artery aneurysms. The figure shows values for sensitivity (top, left), specificity (top, right), positive likelihood ratio (middle, left), negative likelihood ratio (middle, right), and diagnostic odds ratio (bottom) for CTA based on findings of two ...

Fetal-type or fetal posterior cerebral artery (FPCA) is a variant of cerebrovascular anatomy in which the distal posterior cerebral artery (PCA) territory is perfused by a branch of the internal carotid artery (ICA).

2022年9月14日 · Only a few reported studies have used computed tomography angiography (CTA) to image ruptured aneurysms at the junction of the internal carotid artery (ICA) and posterior communicating artery (PcomA) in the context of the adjacent arteries.
