MODELS OF VENOUS FLAPS: OPTIMAL VARIANT
In the experiments on 44 white rats, we studied 4 transformation models of standard skin-fascial epigastric flaps into venous epigastric flaps with different perfusion stage of their venous beds. The analysis of clinical status of replants taking into account their color, capillary response, edema stage, pilosis and desquamation of skin coverings allowed us to assess both venous flap grafting process and esthetic result of this grafting. All arterialized epigastric venous flaps with «increased» and «adequate» arterial perfusion had total necrosis. Venous epigastric flaps on v. epigastrica caudalis had necrosis in 33,3 % of cases. Arterialized venous flaps with «increased» venous outflow were grafted in 100 % of cases with the development of marginal necrosis (3,6 % of cases ) and inflammation (10,7 % of cases).
