Key result
Adult posterior communicating artery bifurcation configuration predominates, occurring in ~63% of adult brains.
Why the study?
Considerable variation exists in the circle of Willis anatomy, which is important to neurosurgeons due to its potential clinical implications.
Cross-Sectional (n=70)
No
The study demonstrates considerable anatomical variation in the posterior bifurcation of the posterior communicating artery, with the adult configuration being the most common (62.85%).

Circle of Willis variations may inform neurosurgical planning; leaves open their prognostic impact on cerebrovascular outcomes.
Thomas Willis in 1962 described the anatomy of cerebral vessels and clearly recognized its functional significance.Considerable variation exist in circle of will is which are already studied and will be studied in this research also.This being important to neurosurgeons as variation may profound clinical implications.70 adult brains were studied out of which 53 are males and 17 are females.Hypoplasia of posterior cerebral artery and posterior communicating artery are observed.Frequency of adult configuration is higher i.e 62.85% .10%showed foetal configuration while 12.85% of circles show transitional configuration in present study.

A 2015 study conducted a cross-sectional in Anatomical variations of the Circle of Willis (n=70). Anatomical variations of the posterior bifurcation of the posterior communicating artery was evaluated on Frequency of adult configuration of the posterior bifurcation. In 70 adult brains, the adult configuration of the posterior bifurcation of the posterior communicating artery was the most frequent (62.85%), followed by transitional (12.85%) and foetal (10%) configurations.
