Echocolor Doppler of the superficial veins of the lower limbs: How To Do It and Normal Findings.

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.
