[Extra- and intraorganic blood channel of the rabbit lumbar vertebrae in health and after cutting the segmentary arteries and veins].
Extra- and intraorganic blood bed of the lumbar vertebrae has been investigated by means of the cast method and vital injection of the vessels with Indian ink-gelatin mixture and subsequent serial translucent preparations. Existence of constant topographo-anatomical relations has been stated between the segmentary arteries and veins with the lumbar vertebrae. Peculiarities in spatial organization of the microcirculatory bed have been revealed in different zones of the vertebral body, as well as peculiarity of blood supply of the epiphyseal osseous marginal plate. Topography and localization of changes in the intraorganic vertebral blood bed have been studied under conditions of bilateral crossing of the segmentary vascular fasciculi at the level of one, two and three vertebrae. Compensatory resources of the vertebral column blood bed are discussed, when large extra-organic trunks in the lumbar part are damaged.
