Sciatic artery: a case, review of literature and attempt of systemization

Abstract

The authors describe a new case of persistent sciatic artery not yet described in the literature. This case is to be added to the four already existing classes of arterial vascularization of the pelvic members of certain animal species. This vascularization concerns two arteries of unequal significance according to the species. An embryological study of this vascularization is also performed. Following these studies, the authors will attempt an arterial systemization and parallel comparison of the different types of animal and embryologic vascularization and human variations of normal.
