• Up to 2 million people in the United States suffer from
DVT blood clots every year1
• Approximately 600,000 experience pulmonary embolism (PE)1
• In the US, complications from DVT blood clots kill almost
300,000 people a year — more than AIDS and breast cancer

What Is DVT?
• DVT is a blood clot that forms
in a vein deep in the body
• Most often occurs in the deep
veins of the legs, either
above the knee or below it
• The blood clot or part of it
may break free (called an
emboli) and become lodged
in the blood vessels of the
lung, causing PE
3
Talk to Your Doctor
•
It is important to share your concerns about
DVT blood clots with your doctor
•
Ask questions and be prepared to provide
accurate information about your lifestyle, diet,
exercise routine, and medications, including
over-the-counter drugs
•
If your mobility is restricted due to illness or
surgery, or if you have ever had a blood clot,
you should talk to your doctor about
preventing DVT

Some Risk Factors for DVT

P4/table
Some of the risk factors that may increase your risk of DVT are4,5:
• Age 40 years or older
• Being overweight
• A personal or family history
of blood clots
• Birth control pills
• Hormone replacement
therapy (HRT)
• Cancer
• Certain heart problems
•
•
•
•
Respiratory failure
Varicose veins
Pregnancy
Surgery, especially hip, knee,
or abdominal surgery
• Currently have restricted
mobility due to a long illness
or surgery
The more risk factors you have, the greater
your chances of developing DVT

 Swelling of the leg
 Unexplained shortness of
breath
 Pain or tenderness in the leg;
the pain is usually in 1 leg and
may only be present when
standing or walking
 Leg feels warm to the touch
 Red or discolored skin
 Chest pain or palpitations
 Anxiety and/or sweating
 Coughing up blood
 Fatigue and/or fainting

Diagnosing DVT
• Diagnosis begins by confirming that you have risk factors
for DVT
• Your doctor will ask about your general health, previous
illnesses, including past episodes of DVT, the medicines
you are taking, and your recent activities
• He or she will conduct a physical examination
• If DVT is suspected, additional tests will be needed to
confirm the diagnosis
7
Treating DVT
• Treatment of DVT can help reduce complications
such as PE
• The main goals in treating DVT are to:
– Stop the clot from getting larger
– Reduce the chance of developing another clot
– Reduce the risk of the clot breaking off in your vein
and moving to your lungs
8
Treating DVT
6/Geerts.Chest.
2004/p3435/C1/L40
• Drugs6
– Anticoagulants (blood thinners)
– Thrombolytic agents (drugs used to dissolve
blood clots)
– Aspirin (treatment with aspirin alone may not be an
effective form of prophylaxis)
8/Ramzi.Am Fam
Phys.2004/P2841/
A10;P2843/C1/L21
• Practical measures8
– Elevate the affected leg whenever possible
– Apply heat to relieve pain and reduce swelling
– Wear compression bandages or support hose
– Avoid long periods of immobility

Protecting Against DVT
• If you are planning surgery or an extended hospital stay,
ask your doctor what you can do to reduce your risk of DVT
– Get out of bed and move around as soon as possible
– Take medicines to reduce the risk of DVT blood clots after
illness or surgery as directed by your doctor
10
Summary
• DVT is a blood clot that forms in a vein deep in the body
• The clot or part of it may break off and travel to the lung
• Certain conditions may increase your risk for deep vein clots
• The more risk factors a person has, the greater the chances
may be of developing DVT
Anyone experiencing any DVT or PE symptoms
should call for assistance and go to a
hospital immediately
11
Summary
• If your mobility is restricted for an extended period
of time due to illness, surgery, or hospitalization,
ask your doctor about protective treatment
• Only about half of the people with deep vein clots
have symptoms
• The main goals in treating DVT are to stop the clot
from getting larger, to decrease your chance of
having another clot, and to reduce the risk of a clot
breaking off in your vein and moving to your lungs
• Medicines are used to treat and/or help reduce the
risk of DVT
Share your concerns about DVT with your doctor
12
Remember…
• DVT doesn't have to happen to you — you and your doctor
can protect against them
• If you develop a DVT blood clot, it can be treated
Knowing your risks for DVT blood clots is the
first step in protecting against them
