Fetal posterior cerebral artery | Radiology Reference Article ...
2024年6月20日 · A fetal PCA describes a situation whereby the posterior communicating artery (PCom) is larger than the P1 segment of the posterior cerebral artery (PCA) and, thus, supplies the bulk of the blood to the PCA 4,5.
Fetal-Type Variants of the Posterior Cerebral Artery and …
2016年9月13日 · 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). In the presence of FPCA, thromboembolism in the anterior circulation may result in paradoxical PCA territory infarction with or ...
Is fetal-type posterior cerebral artery a risk factor for intracranial ...
2017年11月13日 · 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 risk factor for intracranial aneurysm.
Circle of Willis Variants: Fetal PCA - PMC - National Center for ...
2013年3月21日 · Fetal PCA (fPCA) is a common variant of cerebral circulation. Two definitions of fPCA exist in the literature: complete fetal PCA and partial fetal PCA. Complete fetal PCA (cfPCA) is defined as posterior cerebral artery that completely originates from the internal carotid artery ICA with no connection with the basilar artery.
The Fetal Type of Posterior Cerebral Artery - MDPI
2023年1月26日 · 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. Because FPCA occurs in different anatomical configurations of the cW sides, we aimed to document in detail these morphological possibilities of FPCA within the cW.
CT Perfusion Imaging Pitfall Related to Fetal Posterior Cerebral Artery
2013年1月14日 · The purpose of this article is to discuss how a unilateral fetal posterior cerebral artery (PCA) causes perfusion map asymmetry due to anteroposterior bolus arrival discrepancy. We performed region of interest analysis of asymmetric perfusion maps before and after delay correction was performed.
Background: Few MRA- based studies have systematically evaluated the prevalence and laterality of a fetal configuration of the posterior cerebral artery (FTP) in ischemic stroke populations versus other populations. This common variant is important in the setting of acute stroke and secondary prevention decisions.
Anatomic Variant of the Posterior Cerebral Artery | AJR
2012年11月23日 · To our knowledge, we angiographically show a previously unreported anatomic variant of the posterior cerebral artery (Fig. 1A, 1B, 1C). In this variant, the internal carotid artery gives rise to a “fetal” posterior cerebral artery from which the internal occipital artery and its branches, the calcarine artery, parietooccipital artery, and ...
A Fetal-type Variant Posterior Communicating Artery and its …
2019年7月2日 · The fetal posterior communicating artery is a well-established variant of the cerebral vasculature, occurring in 4-29% of the population. This variant can provide unique challenges in the identification and treatment of cerebrovascular disease or a cerebrovascular accident. Here we present a cadaveric case showing the presence of the fetal-type ...
Posterior Cerebral Artery - neuroangio.org
This is the simple phylogenetic explanation for the most common circle of Willis variant — the “fetal” PCA — named as such when early “fetal” arrangement of PCA origin from the ICA persists in the adult form, which is about 20-25% of the time.
