Superficial vein thrombosis (SVT) is a blood clot formed in a superficial vein, a vein near the surface of the body. Usually there is thrombophlebitis , which is an inflammatory reaction around a thrombosed vein, presenting as a painful induration (thickening of the skin) with redness .
It most commonly occurs in superficial veins. Phlebitis often occurs in conjunction with thrombosis and is then called thrombophlebitis or superficial thrombophlebitis. Unlike deep vein thrombosis, the probability that superficial thrombophlebitis will cause a clot to break up and be transported in pieces to the lung is very low. [1]
Superficial thrombophlebitis is a thrombosis and inflammation of superficial veins presenting as a painful induration (thickening) with erythema, often in a linear or branching configuration with a cordlike appearance. [2]: 826–7 [3] Superficial thrombophlebitis is due to inflammation and/or thrombosis, and,less commonly, infection of the

In terms of complications, one of the most serious occurs when the superficial blood clot is associated with a deep vein thrombosis; this can then dislodge, traveling through the heart and occluding the dense capillary network of the lungs This is a pulmonary embolism which can be life-threatening.

Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a blood clot forms in the deep veins. If a thrombus breaks off and flows to the lungs to lodge there, it becomes a pulmonary embolism (PE), a blood clot in the
Blood clots in veins don't typically cause strokes, but they can lead to deep vein thrombosis, aka the reason you should stretch your legs during a long flight. Clots that form in the deep veins ...
Deep and superficial vein thrombosis may in turn be caused by thrombophilia, which is an increased propensity of forming blood clots. [ citation needed ] Arteriovenous fistula (an abnormal connection or passageway between an artery and a vein) may cause chronic venous insufficiency even with working vein valves.
