RESUMO
The authors analyzed results of surgical treatment of 332 patients in whom 410 reconstructive operations were performed on the lower extremity arteries. During 12 months after operation on the aorto-femoral segment with high peripheral vascular resistance reocclusions were noted in 61% of the cases, with normal resistance--in 11.8%, after operation on the femoro-popliteal segment--in 77.1% and 28.3% respectively. According to the findings of computed tomography and magnetic resonance imaging, densitometry the indices were established allowing prognosis of high peripheral resistance in the lower extremity arteries at the preoperative stage. Such indices are considered to be indications to femoro-profundoplasty on the aortofemoral segments or arterio-venous fistula on the femoro-popliteal segment. Such effectively fulfilled interventions could reduce the frequency of reocclusions to 3.1% on the aorto-femoral segment and to 11.8% on the femoro-popliteal segment.
