Phlebitis

phlebitis (fləbī`tĭs), inflammation of a vein. Phlebitis is almost always accompanied by a blood clot, or thrombus, in the affected vein, a condition known as thrombophlebitis (see thrombosis). Blood-clot formation may follow injury or be associated with infections. Thrombophlebitis of deep veins, usually in the legs or pelvis, may occur in patients recovering from childbirth, surgery, or other conditions requiring prolonged bedrest; the clotting mechanism is thought to be impaired when the legs are immobilized. Pregnancy or the use of oral contraceptives predisposes some women to thrombophlebitis. The major danger is that a clot originating in the leg vein may dislodge and travel to the lung, a condition known as pulmonary embolism (see embolus). To avoid the risk of embolism, thrombophlebitis is usually treated with anticoagulants.

phlebitis

Inflammation of the wall of a vein. Causes include nearby infection, trauma, surgery, and childbirth. The area over the vein is painful, swollen, red, and hot. A tender, cordlike mass may be felt under the skin. It usually occurs in surface veins in the lower leg and can be treated with pain relievers and bed rest, with mild exercise after inflammation subsides. Phlebitis can last for years; in such cases, irritation of the vein's inner lining leads to blood-clot formation, a condition known as thrombophlebitis (see thrombosis). In deeper veins, this requires anticoagulants to prevent embolisms.

Phlebitis 

an inflammation of a venous wall caused by an infection or by the introduction of an irritating agent into the vein (aseptic phlebitis). Thrombophlebitis results from the additional presence of thrombosis. Phlebitis occurs most commonly in the veins of the pelvis and in the superficial and deep veins of the extremities. Phlebitis of the portal vein, or pylephlebitis, is usually a complication of an inflammatory or purulent process in the abdominal cavity. Phlebitis may result in sclerosis of the vein. In the treatment of varicose veins aseptic phlebitis is sometimes induced artificially by injecting an irritant into the lumen of a vein for the purpose of obliterating the lumen.
