Blood Clot in the Legs (cont.)

Deep Vein Thrombosis Prevention

The key to prevention is to reverse any risk factors, for example:

  • If you are obese, lose weight.
  • Avoid periods of prolonged immobility. If you are flying on an airplane for a long flight, get up and move around every 15 to 30 minutes, or do simple stretching exercises while seated.
  • Keep the legs elevated while sitting down or in bed.
  • Avoid high-dose estrogen pills, unless they are deemed necessary by your doctor.

If you have had surgery recently, preventive treatment may be prescribed to avoid formation of a clot.

  • You may be instructed to get out of bed several times a day during the recovery period.
  • Sequential compression devices (SCDs) may be placed on the legs. Their squeezing action has been shown to reduce the probability of clot formation. You also may be given elastic compression socks or stockings to wear.
  • Low-molecular-weight heparin or low-dose warfarin may be prescribed to prevent clot formation.
