[Morphofunctional rearrangement of the drainage system of the limbs in acute disorders of blood- and lymph circulation].

The state of venous and lymphatic beds of extremities was studied in rabbits after resection of fragments of main veins and extirpation of popliteal lymph nodes in different series of experiments or in a single step. It has been established that independent of the kind of surgery the total drainage bed of the extremity is changed. Compensation of the disturbed outflow is realized due to development of collateral pathways and direct anastomoses in both beds as well as due to inclusion of paravasal collectors. The terms of recovery of the oxygen strain in muscles, chronaxy and rheobase of muscles as well as the time of passing labeled albumin through the foot-pelvis region (radio-isotope method) are objective criteria for estimation of the functional sufficiency of collateral pathways.
