[The developmental characteristics of the arterial collaterals under ischemia and sympathectomy of the hindlimbs in dogs].
Thrombosis of hind legs arteries and high lumbar desympathization were induced in dogs kept naturally (unleashed and receiving usual meal) and in the vivarium for studying the regularities of collateral blood circulation 7-720 days after the experiment. Roentgenovasography and kinoangiography allowed to assess anatomicofunctional state the vascular system. Results of the examinations performed demonstrated acute and chronic ischemia coupled with significant disorders in local hemocirculation developing in experimental arterial thrombosis and desympathization of the extremity. Natural conditions (usual meal). fresh air, active movement, staying unleashed and so on) were positive for preventing postischemic disturbances in the experimental animals.
