The echocolor Doppler study of the superficial veins of the lower limbs is performed with a 7.5-13 MHz. linear probe or, less frequently, with a 3.5-5 MHz. convex probe (useful in large or edematous patients).
The patient is in ortostatism, with the knee slightly flexed and the weight on the limb not to be examined. The study is performed with longitudinal and transversal scans: attention is needed in the examination of crosses. Morphological, hemodynamic (flux and color-Doppler studies) and topographic evaluations are needed.
Hemodynamic evaluation is performed during breathing or during a static maneuver (such as Valsalva's maneuver or proximal manual compression) or a dynamic maneuver (such as oscillation of the patient or flexion of the fingers).
In this lesson, the methodology of the ultrasound study of the superficial veins of the lower limbs, the anatomical variations of the great and small saphenous veins and the dynamic maneuvers needed are presented.

I am a specialist in Medical Angiology and I am based in Bologna, Italy. Until 2008 (voluntary resignation) I worked at Maggiore Hospital in Bologna as "Dirigente Medico" in the Department of Internal Medicine and as Angiologist in the Angiology Unit with a position of "Alta Professionalità" in "Vascular Ecography and Angiology".
I am currently working in Bologna as an independent professional in the areas of angiology and vascular diagnostics.
I have been a speaker at national and international courses/congress and I have taught duplex ultrasound method in GIUV and SIUMB courses at the Maggiore Hospital, Bologna and courses of echocolor Doppler of extracranial and intracranial arteries at the Stroke Unit of S. Maria Nuova Hospital, Reggio Emilia.
