[Early outcomes of therapy and indirect revascularization surgery in patients with critical ischemia of lower extremities].

OBJECTIVE: To study the immediate results of therapy and indirect revascularization in patients with critical ischemia of the lower limbs.

MATERIAL AND METHODS: The results of medication and surgical treatment were analyzed in 210 patients with critical ischemia of the lower limbs. Atherosclerosis obliterans was diagnosed in 142 patients, thromboangiitis obliterans - in 68 patients. Lesion of femoropopliteal segment was observed in 32 (15.2%) cases, popliteal-tibial segment - 68 (32.8%) patients, tibial and foot segment - 62 (29.5%) cases, foot - 31 (14.8%) cases, multiple-level lesion - 17 (8.1%) cases. Survey consisted of Doppler ultrasound, CT angiography, rheovasography with analysis of rheographic index (RI) and pulse oximetry. Circulatory parameters were compared with identical values in 48 almost healthy persons ("reference group"). The results of medication and surgical treatment were evaluated by using of the scale of Rutherford R.B. et al. (1997).

RESULTS: Conservative treatment was performed in 48 patients (control group). The following types of indirect revascularization operations were performed to stimulate regional circulation: bone trepanation in 42 patients, lumbar sympathectomy in 51 patients, bone trepanation + lumbar sympathectomy in 38 patients, bone trepanation with intraosseous irradiation in 31 cases.

CONCLUSION: Indirect revascularization improves early postoperative outcomes, ensures maintaining support function of the limb and active lifestyle in patients with critical ischemia of the lower limbs. Technical simplicity of these procedures facilitates widespread introduction of indirect revascularization in multi-field hospitals.
