Doppler velocimetry enables three haemodynamic parameters that are extremely useful for the study of venous diseases to be evaluated: blood flow direction, the morphology of the velocity wave and venous pressure. These three parameters are used in association depending on the particular requirements of the diagnostic problem. In the case of suspected deep venous thrombosis, study of the morphology of the velocity wave and clinostatism pressure give good diagnostic possibilities for the iliaco-femoral axis but poor for the leg trunks. In post-thrombotic syndrome, Doppler velocimetry is not so useful because the patient has to remain immobile during the examination while this specific pathology features insufficiency of the muscular pump during walking. In varicose disease, the investigation offers a very high diagnostic capability by evidencing the site and extent of valvular incontinence in the saphena and perforating vessels. The only limitation is the presence of numerous incontinent perforating vessels, but this is infrequent. In this pathology, Doppler v. has almost completely supplanted phlebography because it responds to the needs of modern medicine to replace invasive diagnostic investigations with non-invasive techniques that are equally effective. Finally, two other fields of application are very important for this investigation: the study of a patient with varices prior to saphenic stripping and prior to sclerotherapy. Definition of the origin and course of the reflux ways makes an optimal result possible, even allowing for the evolution of varicosity.
