RÉSUMÉ
This study was designed to determine the value of colored Doppler sonography in the preoperative evaluation of lower extremity arterial lesions before vascular intervention to emphasize the value of such technique in providing information on both the anatomical site and hemodynamic impact of individual atherosclerotic lesions. Eighty lower limbs in 41 patients were evaluated by color duplex scanning and angiography. The lower limb vasculature was divided into fifteen segments [common iliac artery, external iliac artery, common femoral artery, proximal, middle and distal third of the superficial femoral artery, profunda femoris artery, proximal and distal half of the popliteal artery, anterior, posterior tibial arteries and peroneal artery]. In studying different arterial lesions, the sensitivity of CDS at the iliac arteries was 83.8%, at the femoropopliteal arteries 93.75% at the popliteal arteries 91.9%, at anterior tibial arteries 83.8%, at posterior tibial arteries 85.9% and at peroneal arteries 81.4%
