Deep Vein Thrombosis (DVT)

Helping Hand Logo

Deep Vein Thrombosis (DVT) is a blood clot that has formed in a large blood vessel. It may completely or partially block the blood flow in that vein.

There are several risk factors for DVT. These include:

  • hereditary (genetic) factors
  • certain illnesses
  • cancer
  • diabetes
  • smoking
  • inactivity
  • obesity
  • estrogen containing birth control
  • central line catheters
  • congenital heart disease

Signs and symptoms

Early signs of blood clot in an arm or leg include these:

  • pain
  • swelling
  • feels warm
  • red, pale or bluish skin color

Diagnosis and treatment

A DVT will be diagnosed by a physical examination, medical history and a Doppler sonogram (ultrasound).

In most cases a DVT will be treated with an anticoagulation medicine (blood thinner) such as Heparin, Lovenox or Warfarin.

Your child will follow up with a Hematologist (doctor who specializes in blood health).

Precautions for children on anticoagulation therapy

  • Your child should not play contact sports while on blood-thinning medicine.
  • Your child will need to avoid aspirin products and nonsteroidal anti-inflammatory medicines such as Ibuprofen (Motrin, Advil) and Naproxen (Aleve).
