Blood clot risk after brain injury

Deep vein thrombosis (DVT), which involves the formation of a blood clot in a deep vein, may occur after a brain injury because of decreased blood flow and movement in the legs. This becomes less common after a person has begun to get out of bed and is exercising.

Symptoms

  • Swelling, with one arm or one leg bigger than the other
  • Redness, pain, and hot or warm areas in the legs
  • Lumpy or hard spot over or near a vein
  • Low fever (99.F – 101.F) with no other signs of infection

Prevention

  • Do range of motion exercises every day.
  • Stay as active as possible.
  • Drink 6 to 8 glasses of water a day.
  • Cut down or stop smoking in order to improve circulation.
  • Do not strain during a bowel movement.
  • Check the legs for signs of DVT every morning before getting out of bed.
  • Do not wear tight garters, girdles, tight jeans, socks, or knee-high boots.
  • Wear TED hose if they have been ordered by your doctor.

Treatment

  • If you think a DVT is present, call the doctor on an urgent basis.
  • Stay in bed and keep the leg straight.
  • Do not rub the area or exercise it.
  • Do not put pillows under the knee area.
  • Remove tight shoes and clothing.
