The hemodynamic estimation of leg arteries balloon angioplasty effect in 28 patients with ischemic form of diabetic foot using color duplex scanning (CDS) and laser Doppler flowmetry (LDF) was done. Average — 72.2±1,7 year. All of them had tissues loss at the background of popliteal-tibial segment lesion. Anterior tibial artery angioplasty was performed in 19 patients, posterior — in 4 people, popliteal artery lesion — in 1 patient, peroneal artery — in 10 patients. Macrohemodynamic parameters recorded by CDS in both tibial arteries were measured at foot before surgery and 1 day after. Increase of blood flow velocity (PSV) to 73,2% (p<0,01) in recanalized artery was revealed. In arteries with collateral revascularization increase PSV gain has made 26,9% (p<0,01) and resistivity index had increased (Ri) (p<0,01). LDF parameters recorded in two standard points on the foot, according to anterior and posterior tibial arteries angiosomes prior to surgery and daily for 5 days. No significant changes in microcirculation have been identified. The long-term results analysis (6 months) showed limb salvage in 96.2% of cases (1 large amputation), in 80.8% cases — healing of trophic disorders.

Key words: diabetic foot, color duplex scanning, laser Doppler flowmetry.
