What are the causes of deep vein thrombosis?

Blood is meant to flow; if it becomes stagnant there is a potential for it to clot. The blood in veins is constantly forming microscopic clots that are routinely broken down by the body. If the balance of clot formation and resolution is altered, significant clotting can occur. A thrombus can form if one, or a combination of the following situations is present.

Immobility

  • Prolonged travel and sitting, such as long airplane flights ("economy class syndrome"), car, or train travel
  • Hospitalization
  • Surgery
  • Trauma to the lower leg with or without surgery or casting
  • Pregnancy, including 6-8 weeks post partum
  • Obesity

Hypercoagulability (coagulation of blood faster than usual)

  • Medications (for example, birth control pills, estrogen)
  • Smoking
  • Genetic predisposition
  • Polycythemia (increased number of red blood cells)
  • Cancer

Trauma to the vein

  • Fracture to the leg
  • Bruised leg
  • Complication of an invasive procedure of the vein
