title: [Hemodynamic steal syndrome in the distal limb segments in patients treated by Ilizarov method].
abstract: Complex physiological examination of 149 patients with lower limb bone defects was performed using Doppler ultrasonography, rheovasography, percutaneous measurement of oxygen and carbon dioxide during treatment with Ilizarov apparatus. Within the process of treatment with Ilizarov apparatus, with marked collateral circulation, steal syndrome is noted in the distal parts of limb due to the effect of "functional shunting" in the zone of distraction regenerate bone. Steal syndrome during treatment by Ilizarov technique is registered, according to rheovasography and Doppler data, in 57% of patients with a defect in the femoral bone, in 24% of patients with post-traumatic defects in shin bones, and in 85% of patients with congenital defects in shin bones. In the compensated form of steal syndrome in the distal segment, according to polarography data, normoxia combined with hypocapnia is registered; oxygen requirements at rest are met by its more complete utilization, and activation of anaerobic processes.
