"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."
"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. When bilateral fetal PCAs are present, the basilar artery will be significantly smaller in calibre than normal ref."
