Abstract

The perforating vessels supply very important regions of the brain stem and diencephalon, as well as the basal ganglia and internal capsule. Some of their micro-anatomical characteristics are still not well known. The aim of this study was to examine and evaluate the features of all the perforating vessels. The arteries of 24-32 cerebral hemispheres, diencephalons and halves of the brain stem were injected with India ink mixture or methylmethacrylate, and microdissection was performed or the vascular casts were produced and examined under the sterescopic microscope. It was noticed that the perforators ranged from 0 to 14 in number, with the smallest mean value (1.1) for the diencephalic perforators and the largest one (8.1) for the lenticulostriate arteries. The smallest mean diameter (175 μm) was found in the group of the perforators of the anterior communicating artery, whereas the largest one is related to the Heubner's artery (668 μm), the diencephalic thalamoperforating vessels (562 μm), the premamillary vessel (489 μm) and the lenticulostriate arteries (469 μm). The perforators most frequently originated from the pial branches of the basilar artery (91.7 %) and of the posterior cerebral artery (59.4 %). The common stems w...Continue Reading
