Assessing the impact of fetal-type posterior cerebral artery variations on cerebral hemodynamics

Thi Thanh Giang Le,
Sang Won Ryu,
Jung Jae Yoon
et al.

Abstract: The circle of Willis (CoW) is a critical, arterial structure that ensures balanced, cerebral-blood supply. The fetal-type posterior cerebral artery (f-PCA) is a CoW variant that can significantly affect hemodynamics and elevate the risk of cerebrovascular diseases. This study used computational fluid dynamics simulations and a patient-specific, three-dimensional model to evaluate the hemodynamic effects of the f-PCA variants on cerebral-blood flow and key hemodynamic indices—such as time-averaged wall-shear st… Show more
