[Role of non-invasive vascular diagnosis in the study of "diabetic foot"].

The Authors examine the possibilities of instrumental diagnosis in patients with the "diabetic foot" syndrome. The lack of clinical relevance of the so called "microangiopathy" is stressed, because. Indeed, either the "macroangiopathy" or the diabetic neuropathy are responsible for almost all the symptoms of this syndrome. In the differential diagnosis between these two major sequelae of diabetes, with consequently wide differences in the therapeutic choices, the Doppler ultrasound examination has been of paramount usefulness, because it is very sensitive and specific in detecting and localizing any lesion suggestive of macroangiopathy.
