[Hemodynamic bases for the automated quantification of the degree of obstruction in the peripheral arteries of diabetic patients].

In order to improve in the early diagnosis of an arterial occlusion, we proposed the bases of an automatized system that allows to recognize the hemodynamic features of diabetic patients in different stadiums of their disease. Fifty-four patients with type-II diabetes were studied. We recorded the arterial flow curves in the bilateral femoral, popliteal, pedia and tibial-posterior arteries from all of our patients. In the distal arteries from patients with hemodynamics disturbances, we found normal values of the variants measured: maximal systolic speed flow (Max A), maximal diastolic speed flow (Max D), Peurcelot's resistance (RP), pulsatility index (PI) and spectral band (SB).
