Three types of distal segment were distinguished. In the first type (42.9 %), the terminal division was located either in the calcarine sulcus or in the quadrigeminal cistern. In the second type (41.4 %), the terminal division had the same position, but the distal segment, in addition to its terminal stems, also gave off the common temporal artery. In the third type (15.7 %), the terminal division was seen in the ambient cistern. The distal segment of the PCA gave rise to several collateral branches: the collicular artery (2.8 %), the anterior (28.6 %), middle (30.0 %), and posterior (28.6 %) hippocampal arteries, the proximal (82.9 %) and distal (20.0 %) lateral posterior choroidal arteries, the proximal (40.0 %) and distal (41.4 %) medial posterior choroidal arteries, the peduncular, thalamogeniculate and splenial branches, the lingual gyri artery and the temporal arteries. Several anatomic variants of the distal segment were observed in this study: fenestration of the distal segment (1.4 %), location of the distal segment dorsal to the uncus (2.8 %), origin of the collicular (2.8 %) and anterior choroidal arteries (1.4 %) from the distal segment, and protrusion of the parieto-occipital arterial loop into the lateral ventricle (2.8 %). The authors discuss the clinical significance of these anatomic data. © 1988 Springer-Verlag.Cerebrovascular diseaseDistal segmentNeurosurgeryPosterior cerebral arteryVascular anatomyAnatomic basis for surgical approach to the distal segment of the posterior cerebral artery
