Your Care Instructions

Major blood vessels in the body

A deep vein thrombosis (DVT) is a blood clot in certain veins of the legs, pelvis, or arms. Blood clots in these veins need to be treated because they can get bigger, break loose, and travel through the bloodstream to the lungs. A blood clot in a lung can be life-threatening.

Your child may need to take a blood thinner for 3 to 6 months or longer. Blood thinners help prevent new blood clots from forming. Blood thinners will not get rid of a blood clot your child already has, but they will keep the clot from getting bigger. Your child's body will get rid of most or all of the blood clot he or she already has over time.

If your child is taking a blood thinner, be sure you get instructions about how to take this medicine safely. Blood thinners can cause serious bleeding problems.

The doctor has checked your child carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.

Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.

How can you care for your child at home?

  • Be safe with medicines. Have your child take medicines exactly as prescribed. Call your doctor or nurse call line if you think your child is having a problem with his or her medicine.
  • Have your child wear compression stockings if your doctor recommends them. These stockings are tighter at the feet than on the legs. They may reduce pain and swelling in your child's legs. But there are different types of stockings, and they need to fit right. So your child's doctor will recommend what your child needs.
  • When your child sits, use a pillow to raise the arm or leg that has the blood clot. Try to keep the arm or leg above the level of your child's heart.
  • Have your child wear medical alert jewellery that shows that he or she is on a blood-thinning medicine.

When should you call for help?

Call 911 anytime you think your child may need emergency care. For example, call if:

  • Your child passed out (lost consciousness).
  • Your child has symptoms of a blood clot in his or her lung (called a pulmonary embolism). These include:
    • Sudden chest pain.
    • Trouble breathing.
    • Coughing up blood.

Call your doctor or nurse call line now or seek immediate medical care if:

  • Your child has new or worse trouble breathing.
  • Your child is dizzy or light-headed, or feels like he or she may faint.
  • Your child has symptoms of a blood clot in his or her arm or leg. These may include:
    • Pain in the arm, calf, back of the knee, thigh, or groin.
    • Redness and swelling in the arm, leg, or groin.

Watch closely for changes in your child's health, and be sure to contact your doctor or nurse call line if:

  • Your child does not get better as expected.
