Morphometric Analysis of Normal and Variant Anatomy of Posterior Cerebral Artery and the Incidence of Fetal Posterior Cerebral Artery in Uttar Pradesh Region

Journal of the Anatomical Society of India, 2022
Introduction: The aim is to study morphometric analysis of normal and variant anatomy of posterior cerebral artery (PCA) and incidence of fetal PCA (FPCA) in Uttar Pradesh region. The PCA and its cortical branches supply blood to the occipital lobe, inferomedial temporal lobe, and portions of posterior inferior parietal lobe ...

Fetal-type posterior cerebral artery and association of rupture in posterior communicating artery aneurysms: A systematic review and meta-analysis

Clinical Neurology and Neurosurgery, 2023
The morbidity and mortality of intracranial aneurysm rupture motivate the risk evaluation of the patient´s characteristics and aneurysm's morphology. Brain vessel variants lead to hemodynamic changes that could increase risk. This study aims to evaluate the fetal posterior cerebral artery (fPCA) as a risk factor for the formation, rupture, and ...

CT Perfusion Imaging Pitfall Related to Fetal Posterior Cerebral Artery

American Journal of Roentgenology, 2012
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.Perfusion asymmetry becomes unapparent using a delay ...

Accuracy of CT angiography in the assessment of a fetal origin of the posterior cerebral artery

European Radiology, 2004
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 fetal origin of the PCA.

Potential proneness of fetal-type posterior cerebral artery to vascular insufficiency in parent vessel occlusion of distal posterior cerebral artery aneurysms

Journal of Neurosurgery, 2012
Object The purpose of this study was to report the potential proneness of a fetal-type posterior cerebral artery (PCA) to develop vascular insufficiency in parent vessel occlusion of distal PCA aneurysms. Methods Between January 2005 and January 2011, 19 patients (9 females and 10 males) with 20 distal PCA aneurysms (16 dissecting and 4 saccular ...

A novel classification for posterior communicating artery aneurysms in the presence of fetal posterior cerebral artery: A registry-based study

Interventional Neuroradiology
Background and objectives Fetal posterior cerebral artery (fPCA) is a common anatomical variant where the P1 segment is hypoplastic or absent, and the posterior communicating artery supplies the posterior cerebral artery (PCA) territory.
