[The topographical characteristics of the blood vessels of the human spine].

Methods of roentgen angiography, injections of India ink-gelatin mass, morphometry, microscopy and others were used in an experiment carried out on non-fixed corpses of children and adults for studying functional topography of arteries and veins of the vertebral column. Posterior intercostal and lumbar arteries were established to give off 3-4 anterior and 3-5 lateral branches from each side which penetrate into paradiscal segments of the vertebral body. In 92% one lateral branch runs downwards to the intervertebral disc and lower vertebra. Great number of vertical branches of various diameters come off from intraorganic arteries of horizontal orientation of paradiscal segments to intervertebral discs. The medial segment contains distinct basivertebral, anterior and lateral veins falling into venous plexuses surrounding the vertebrae. The diameter of these veins depends on specific properties of angiotopography, sizes and shape of the vertebra. The regular trends in question aid to explain the question of pathogenesis of hematogenic lesions of the vertebrae and to choose the methods of osteoplastic operations.
