Blood Clots in the Leg Veins

Blood clots can happen in veins. A blood clot in a vein close to the skin isn’t likely to cause problems. But having blood clots in deep veins is called deep vein thrombosis. Deep vein thrombosis happens most often in the legs. This problem can lead to a blood clot in the lung ( pulmonary embolism ). The deep veins of…

Blood Clot in a Vein

A blood clot (a clump of blood) that forms in a vein and causes inflammation is called thrombophlebitis. Symptoms include pain, tenderness, warmth, and redness along the length of a vein. A clot may form either in a vein just under the surface of the skin (superficial thrombophlebitis) or in a vein deep in the leg (deep…

Superficial Venous Thrombosis

A superficial venous thrombosis is a blood clot in a vein that is close to the surface of the skin. A superficial thrombosis usually forms a firm lump, sometimes like a rope, under the skin. Often the skin is red and tender. The skin may look infected, but an actual infection is not common. If the area around the clot…

Vena Cava Filter

A vena cava filter is an umbrella-shaped barrier device that is inserted into the large vein that returns blood to the heart from the abdomen and legs (inferior vena cava). This filter helps prevent blood clots that form in the deep veins of the lower limbs from traveling to the lungs and heart where they may block…

Pulmonary Embolism

Pulmonary embolism happens when an artery in the lung is suddenly blocked. It’s usually caused by a blood clot in a leg vein that breaks loose, travels to a lung (pulmonary) artery, and blocks blood flow. This is very serious and can be deadly.
