<unk>  <unk>  is a blood clot formed in a superficial<unk> , a<unk>  near the surface of the body. Usually there is thrombophlebitis, which is an inflammatory reaction around a thrombosed<unk> , presenting as a painful induration (thickening of the skin) with redness.<unk>  itself has limited significance (in terms of direct morbidity and mortality) when compared to a deep<unk><unk>  (DVT), which occurs deeper in the body at the deep venous system level. However,<unk>  can lead to serious complications (as well as signal other serious problems, such as genetic mutations that increase one's risk for clotting), and is therefore no longer regarded as a benign condition. If the blood clot is too near the saphenofemoral junction there is a higher risk of pulmonary embolism, a potentially life-threatening complication.<unk>  has risk factors similar to those for other thrombotic conditions and can arise from a variety of causes. Diagnosis is often based on symptoms. There are multiple possible treatments, with the goal of providing symptomatic relief and preventing complications.
