Stud-ies have described angiographic anatomical varia-tions in the circle of Willis in populations diverse in age, gender, race, and geographical region using different research methodologies, including study designs and diagnostic modalities. This compre-hensive review compares and contrasts the find-ings of these studies in terms of prevalence, comorbidities, and clinical applications of anatomi-cal variations across these different studies. More-over, an embryological and physiological basis of these variations has been discussed in this review. ER -
