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. The P1 can be small (hypoplastic) or absent in this setting.
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.
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 ...

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.
Mechanisms of Stroke in Patients with Fetal Posterior Cerebral Artery
2022年1月30日 · The fetal-type posterior cerebral artery (FTP) is a normal variation of the posterior cerebral artery (PCA), occurring in 3–36% of general population. The effects of the FTP in stroke mechanisms remain debatable. We aimed to investigate the differences in stroke mechanisms and lesion locations between patients with and without FTP.

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.
Are Fetal-Type Posterior Cerebral Arteries Associated With an ... - PubMed
2019年6月1日 · Background: Fetal-type posterior cerebral arteries (F-PCAs) might result in alterations in hemodynamic flow patterns and may predispose an individual to an increased risk of posterior communicating artery aneurysms (PCoAAs). Objective: To determine the association between PCoAAs and the presence of ipsilateral F-PCAs.
Abstract WP225: Fetal-Type Posterior Cerebral Artery: A Not So …
2020年2月12日 · Introduction: The fetal-type of the posterior cerebral artery (ftPCA) is a remnant of the embryonic cerebral vasculature and describes a predominant supply of the PCA territory by a branch of the internal carotid artery. It is usually considered a benign anatomical variant with a prevalence ranging between 3% and 40%.
Fetal variant of posterior cerebral artery: just a physiologic …
2021年1月3日 · Fetal origin of PCA (fPCA) is an anatomic variant of the PCA where the caliber of the PCoA is greater than the P1 segment of PCA [1]. Its presence causes a dominant perfusion of the occipital lobe by the ipsilateral ICA.
Objective: To determine the prevalence and laterality of FTP configurations in MRI- DWI verified acute ischemic stroke patients investigated with MRA, and compare the findings with an unselected hospital population investigated with computed tomog-raphy angiography (CTA).
