Abstract
In the last 40 years ultrasound (US, echosonography) has found its place in almost all medical disciplines. A powerful diagnostic method has been created by joining CW Doppler technique and B mode
ultrasound with Colour Flow Imaging (CFI)Arterial occlusion is detected by measuring the Peak Systolic Velocity Ratio (PSVR) which
differentiates the flow rate in the proximal and in the stenotic portion of the vessel. In diagnosing venous pathology we use respiratory phase, compressibility of the veins, flow continuity, and augmentation
phenomenon with high specificity and sensitivity. In our institution over 600 patients are submitted annually to vascular US examination. Follow-ups of previously diagnosed conditions still occupy nearly two-thirds of them. New vascular diagnoses occur on average in about 120 cases (around 25%). These are mainly deep vein thrombosis
and peripheral occlusive arterial disease. A small number of aneurysms which are more common in the male population, and a small number of AV fistulas, usually iatrogenic, have also been found.
Unexpected “nonvascular” findings are not so rare, occurring in about 10% of the examinations, with a huge benefit for the patients and for the wards as well.
