Superficial vein thrombosis (SVT) is a type of venous thrombosis, or a blood clot in a vein, which forms in a superficial vein near the surface of the body. Usually there is an inflammatory reaction around the vein which presents as a painful induration with erythema. SVT has a limited clinical significance (in terms of morbidity and mortality) when compared to a deep vein thrombosis (DVT), which occurs deeper in the body, at the deep venous system level. If the blood clot is too near from the sapheno-femural junction there is a bigger risk of pulmonary embolism.[1][2][3]
