The Echocolor Doppler in the Diagnosis of the Superficial Vein Thrombosis

The superficial vein thrombosis (SVT) of the lower limbs is an inflammatory-thrombotic pathology in which a thrombus develops in the saphenous veins or its tributaries.

It is needed to distinguish the SVT on varicose or on nonvaricose veins as well as its proximal (above-knee) or distal localization (below-knee) for prognostic and therapeutic  implications.

The clinical findings can be used to establish the diagnosis but they are not reliable in determining in most cases: a) the proximal extent of SVT (the thrombus usually extends beyond the area of clinical involvement); b) whether the SVT is associated with deep vein thrombosis (DVT).

So further tests are required: the echocolor Doppler is the diagnostic tool of choice in the detection of SVT and can be used routinely for serial evaluation to document any disease progression or resolution.

In this lesson the echocolor Doppler role is presented for the diagnosis of the SVT (in acute phase and follow up) and for the diagnosis of the SVT associated with occult DVT.
