The first visit is the most important moment for the classification of the patient. The inspection and palpation together with normal symptomatic maneuvers ( Perthes and Trendelembourg) show signs of chronic venous insufficiency in the various stages of the disease (telangiectasias, varices , edema, pigmentation, Hypo-dermatitis , white atrophy and ulceration)
Today, the diagnostics with ultrasound together with Doppler and color is the indispensable method to morphologically see the arteries and veins of the body, study the flow velocity and its direction. This allows to diagnose totals or subtotals obstructions of arteries and veins, any expansions, their relationship with the surrounding organs and in the case of peripheral veins the functioning of the valve apparatus thus determining the possible undesired back-flow.
This kind of examination is little used by now; it shows in an indirect manner the overall functioning of the vascular apparatus by measuring the variations in volume of the limbs or the capillary flow of the skin
Instrument that has marked in the 1980s the beginning of the study of the blood vessels functioning. Precisely exploiting the Doppler effect shows on the screen a curve that is an expression of the variations in the speed of the flow in the arteries and veins. Still used for the thinner blood vessels and for the digital capillary flow in functional pathologies.
The intense light produced by the tool penetrates into the subcutaneous showing the presence of vessels not directly visible and is used for marking or mapping of varices before surgery and for guiding the sclerotherapy.
