Common Symptoms of DVT

DVT: What is Deep Vein Thrombosis?Your venous disease has progressed to DVT. Now what?!

Deep Vein Thrombosis (DVT) is a blood clot in a deep vein that typically forms in the leg and is at risk for breaking off traveling to the lungs and causing pulmonary embolism (PE). This is a very serious condition and should be treated immediately.

Clots can also be found in the arms, but are more common in the legs, and usually only one, not both5. DVT rarely occurs in children, but the risk increases significantly over the age of 401. Be alert to possible symptoms and call your doctor as soon as possible if you experience these symptoms. DVT can be a symptom of other conditions that affect how your blood clots and you should consult your doctor for an accurate diagnosis.

Because a deep vein thrombosis (blood clot) can break off and travel to your lungs, you should be aware of the warning signs of a pulmonary embolism (PE). This is a life-threatening condition and quick treatment could save your life or reduce the likelihood of future problems.

Warning signs of Pulmonary Embolism (PE):

  • Chest pain: often feels worse if you breathe deeply or cough
  • Coughing up blood
  • Rapid pulse rate
  • Feeling dizzy or fainting
  • Sudden shortness of breath or rapid breathing

If you smoke, are over 60, overweight, and you sit for long periods of time (on a plane, at your desk, confined to bed or had recent surgery, etc.), your risk for blood clots is higher.

Symptoms of DVT

Common symptoms of DVT are:

  • Leg swelling, with tenderness, possible discoloration and a feeling of warmth to the touch
  • Pain that starts in your calf and can feel like cramping or soreness
  • Veins you can see that seem to be bulging

If you experience discomfort or any of these symptoms appear suddenly, it’s time to pick up the phone and call your doctor.

Testing2 and Treatment of Deep Vein Thrombosis

In order to confirm a diagnosis, your doctor may conduct one or more tests as well as ask about your medical history, symptoms, overall health, and activity level.

Duplex ultrasound is a non-invasive test and does not involve any radiation. Images from that scan may confirm the presence of a clot or may reveal other problems or conditions in the veins.

Venography is a special type of X-ray using radioactive dye injected into a vein. The dye provides contrast to the images and allows the doctor to see your veins and where they may have a clot.

Magnetic resonance imaging (MRI)3 provides a much more detailed view of the area you’re testing and can show things that an X-ray or Ultrasound can’t. Images are created by pulses of radio waves and stored digitally so they can be compared to other images over time or viewed from a remote location. Sometimes, you may receive a dye injection to provide more detail in the image.

See your Doctor 4

It’s important to get an appointment and be seen by your doctor quickly…don’t wait. DVT is considered an emergency condition. It’s helpful to bring along the following information:

  1. Write down all your symptoms – not just those you think are part of a DVT diagnosis
  2. Have a list of all your current medications with you as well as vitamins and supplements
  3. Provide a brief list of any family members who may have a history of blood-clots
  4. Share any hospitalizations, surgeries, illness or accidents as well as recent travel
  5. Make a list of any questions you have for the doctor

Being aware of the symptoms of DVT and providing detailed personal information during your visit will assist your doctor in determining the next steps for diagnosis and treatment.
