We would like to present a case with fetal posterior cerebral artery duplication and anterior cerebral artery trifurcation, which we detected using magnetic resonance angiography. We believe this is the first case defined in the literature. Embryological explanation of posterior cerebral artery variations is discussed in light of the literature.

Mechanisms of Stroke in Patients with Fetal Posterior Cerebral Artery
Journal of Stroke and Cerebrovascular Diseases, 2022The 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.A total of 394 ...

The purpose of this study was to investigate the risk factors associated with recurrence of posterior communicating artery aneurysms after treatment and to evaluate the significance of fetal-type posterior cerebral artery as an independent risk factor for recurrence of posterior communicating artery aneurysms.The clinical and radiological findings of ...

The most common neurovascular variant is the fetal posterior cerebral artery (FPCA), in which the P1 branch is absent or hypoplastic, and the majority of P2 supply is derived from the anterior circulation. While there are reports of hyperplastic anterior choroidal arteries (AChA) with supply to the temporo-occipital and calcarine regions, no reports of

The recanalization of posterior communicating artery (PCoA) aneurysms after endovascular treatment has been analyzed by various factors. However, the differences between adult and fetal types of posterior cerebral artery (PCA) have not been fully investigated.

Flow diversion may have advantages in the treatment of posterior communicating artery (PComA) aneurysms associated with a fetal origin posterior cerebral artery (PCA), which can be challenging to treat with conventional techniques. However, a PComA incorporated into the aneurysm may prevent or delay aneurysm occlusion.

Potential effect of fetal origin of posterior cerebral artery on the arterial spin labeling sequence
Journal of Neuroradiology, 2020Arterial Spin Labeling (ASL) is prone to a number of artifacts, which may affect its diagnostic accuracy. To avoid these pitfalls, possible effects on the ASL measurements should be identified. Perfusion asymmetry in the posterior cerebral artery (PCA) territory may be induced by the fetal-type PCA. Whenever a posterior left-right asymmetry is observed

A case of aneurysm of the posterior temporal artery branched from the fetal posterior cerebral artery. [PDF]
Hiroshima journal of medical sciences, 1989 The authors report a case of a ruptured saccular aneurysm located on the posterior temporal artery branched from the fetal posterior cerebral artery. This site of aneurysmal origin is extremely rare. The aneurysmal neck clipping successfully performed via a middle subtemporal route.
