[Pulsatility index and circulatory resistance factor in arteriopathies of the lower extremities].
Pulsatility index (P.I.) and Resistance factor (Gosling) are computed on Doppler arterial recordings in 43 healthy subjects and 95 arteriopathies (184 lower limbs). The statistical analysis points out the high significance of tibial P.I. for early diagnosis of arterial disease, of femoral P.I. for assessment of aorto-iliac stenosis or obstruction and of the ratio tibial P.I./femoral P.I. in the evaluation of leg arteries patency. The popliteal P.I. discriminates proximal and distal lesions.
