Abstract:
Pathology of the central perforating arteries of the brain has an important place among the cerebrovascular diseases. Since the structure of a hemorrhagic stroke hypertensive intracerebral hemorrhage
occupy the first place. From all off the central perforating arteries, the greatest interest presents the lentikulostriales artery middle cerebral artery (MCA), a gap which leads to the formation of hemorrhages
in putamen area. Due to the functional significance of these arteries goal: to identify options for building
lentikulostriales arteries depending on the length of the sphenoid segment of the MCA in patients with
different forms of the skull. The study was conducted at the Department of Topographical Anatomy and
Operative Surgery KrasGMU. Studied 68 drugs with drawn from the brain dead who died of causes unrelated to the CNS. Prior to removal of the brain were measured longitudinal and transverse size of the
skull with cranial index calculation and allocation: dolicho, meso-and brachycephalic. In the brain after the brandy seized arterial and microdissection, studied and extending from the SMA it lentikulostriales
artery. Sphenoid segment of the area (SMA) arteries: from the bifurcation of the internal carotid artery
to the bifurcation. The average length of the sphenoid segment amounted to 15,9 ± 2,3 mm. According
to the literature there are three groups lentikulostriales arteries: medial group - direct the course of the
artery (4 branches), the intermediate group - in the form of candelabrer-shape artery (up to 8 branches),
and lateral group of S-shaped arteries (up to 9vetvey). 'This type of structure lentikulostriales arteries
is called a «classic.» According to our data, this type of structure occurs in 62% of cases, most often in
dolichocephals (80%). Besides the classical type of structure we have selected an intermediate type of
structure, in which the background to the medial and lateral group of arteries in the middle parts of the
MCA was located only one type of container beam, radiating to the substance of the brain up to eight
branches. This type of structure met lentikulostriales arteries in 20% of cases, most often in brachycephalic (25%). Of greatest interest is allocated to us, the beam type structure lentikulostriales arteries. In
this type of structure throughout the MCA in the middle parts of the beam had the only large vessel,
smack in the matter of the brain up to 14 branches. This type of structure occurs in 18% of cases. Most
often in brachycephalic (30%) and did not meet with dolichocephals. The analysis of options for building
lentikulostriales arteries, depending on the length of the sphenoid segment of the MCA. The classic type
of structure met with the length of the sphenoid segment of 3.1 mm to 20mm. The intermediate type of
structure - with a length of 11.8 mm to 18.1 mm. Beam-type structure with a length sphenoid segment
from 11.7 to 15.2 mm. The correlation analysis between the length and type of sphenoid segment lentikulostriales arteries revealed that the shorter barrel of the AGR, the more likely the beam and an intermediate type of structure. Thus, the length of the sphenoid segment can serve as a guide for determining the
type of structure lentikulostriales arteries.
