Background: Course and territory supplied by the posterior communicating artery (PCoA) are well known but its origin and calibre are quite variable. Increasing incidence of microsurgical operations in the areas that are supplied by PCoA requires detailed knowledge about the anatomic variations of this artery. The aim of the present study is to examine the anatomical variability of the PCoA, with special emphasis on patients that underwent surgery via the pterional approach.
