Deep Vein Thrombosis

Overview of Deep Vein Thrombosis

Deep vein thrombosis refers to a condition in which a blood clot forms within a vein. This is most common in large veins of the legs or pelvis. Although the development of a deep vein thrombosis may not produce any dangerous problems, portions of the clot may break off and float to the lungs where they produce a pulmonary embolism.

Causes of Deep Vein Thrombosis

Deep vein thrombosis is caused by slow flow through the veins in combination with the inherent nature of blood to clot. Damage to the wall of the vein may produce or accelerate these changes. Prolonged bed rest, recent surgery, pregnancy, the use of oral contraceptives and inherited diseases which produce increase coogulability of the blood all may increase the risk of deep vein thrombosis.

Signs and Symptoms of Deep Vein Thrombosis

Typical symptoms associated with deep vein thrombosis include pain and swelling in the involved extremity. Shortness of breath, chest pain, and cough may herald the development of a pulmonary embolism.
