Analysis of 85 patients with symptoms of peripheric
arterial insufficiency by comparison of the Doppler hemo.
dynamic study and arteriography.
To this end, each limb is divided into three segments:
the aortoiliac, the femoropopliteal and the distal
popliteal segments. In the 320 segments studied by
Doppler a 92% of sensibility, a 97% of specificity and a
high reliabilily coefficient in the diagnosis were found,
revealed by a 0,89 rate of Youdan index, which turns
Doppler into a first class method for the study of pa•
lients with peripheric vascular problems.
