[Intraorganic blood vessels of the intestinal graft after its ortho- and heterotopic transplantation].

In experiments, performed on 85 dogs of both sex ortho- and heterotopic total autotransplantation of the small intestine and extracorporal connection of the allogenic segments of the small intestine have been carried out. Certain dependency of morphological changes of the intraorganic blood bed on the operation model has been stated. Essential changes in the blood bed at the heterotopic autotransplantation depend on inadequate regional hemodynamics in the graft. Therefore, the heterotopic model should be considered less preferable than the orthotopic one. One of the peculiarities in reconstruction of the intraorganic vascular bed after ortho- and heterotropic transplantation of the small intestine is, evidently, opening of lympho-venular anastomoses.
