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. Methods: 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. Results: 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 (175μm) was found in the group of the perforators of the anterior communicating artery, whereas the largest one is related to the Heubner's artery (668μm), the diencephalic thalamoperforating vessels (562μm), the premamillary vessel (489μm) and the lenticulostriate arteries (469μm). 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 were most often formed by the perforators of the basilar (79.2%), posterior cerebral (75.0%) and middle cerebral arteries (40.6%). Some perforators arose close to or from the terminal divisions, the branching sites or the junctions of the parent arteries, where the saccular aneurysms most often develop. The anastomoses among the perforators were present in a range from 6.3% to 53.2%. Conclusions: The micro-anatomical data obtained may be useful for neurosurgeons when operating at the base of the brain, as well as for a neurological and radiological evaluation of the perforators in the occlusive cerebrovascular disease, or in the cases of an aneurysm, arteriovenous malformation (AVM) or tumour presence.
