Abstrakt: The posterior communicating part of the cerebral arterial circle of Willis is formed by 4 arteries: the right and left P1 segment of the posterior cerebral arteries (PCA) and posterior communicating artery (PCoA). Those have been examined on 50 fresh or formalin preserved human brains, using as study method the dissection and/or the plastic injection, followed by dissection or corrosion, also 20 angiograms, 30 CAT scan angiograms and 120 MR-angiograms. We have assessed the great aspect and caliber variability of P1 segment and PCoA and also the collateral branches that are rising from these arteries and their distribution territories. Our data have been compared with other anatomical studies publicized. The greatest variability was observed in PCoA, and we observed that there was a direct correlation between the differences in size between the P1 segments and the diameter of the PCoA.
