title: [Effect of Ilizarov tibial lengthening on limb blood flow].
abstract: The experiment in 23 adult dogs was based on the study of volumetric blood flow velocity in the superficial femoral artery and femoral vein, pulse changes in blood filling of the m. gastrocnemius in the conditions of tibial lengthening to 17.5-23% from the initial length. Complex changes in the blood flow parameters were revealed after surgical intervention and within 7 distraction days. When the distraction ended, the volumetric blood flow velocity in the femoral artery was reduced by 19% and the blood flow out of the vessel was improved by 17%. When fixation was over, the volumetric blood flow velocity in the vessel increased by 37% and the improved outflow preserved. At each experimental stage, there was an increased volumetric blood flow velocity in the femoral vein as compared to its value in the control group, its correspondence to the superficial femoral artery as well as similar dynamics in blood flow changes in the femoral vessels and m. gastrocnemius. The findings show that the vascular system of bone regeneration provides accelerated arterial blood transportation into the venous system during organotypical bone area formation.
