What is a DVT of the leg?

A DVT is a blood clot that form in the veins of the lower leg. A DVT is considered a medical emergency because the clot can break loose and travel to your lungs causing a pulmonary embolism (PE). A PE is when a blood clot gets lodged into your lung and can cause trouble breathing and possibly death. 

What are causes of DVT?

Some risk factors are previous DVT, family history of DVT, blood clotting disorders, varicose veins, dehydration, obesity, cancer, hormone therapy, pregnancy, birth control, age >40, long periods of immobilization, recent surgery, trauma, smoking, 

What are the signs and symptoms of a DVT?

Sudden swelling, redness, pain, and warmth to the leg, typically the calf. Not all DVTs have severe symptoms and some people may have mild to no symptoms. 

How to diagnosis a DVT?

If you suspect a DVT it is important to see your doctor immediately. Your doctor will get labs, an ultrasound to diagnose the DVT, and possible further imaging if you are experiencing trouble breathing. 

How to treat a DVT?

Your doctor will put you on a blood thinner and possibly refer you to a vascular surgeon depending on the location and size of the blood clot. Preventively a person can decrease risk factors such as decreasing smoking, loosing weight, wear compression stockings, and getting up every 2-3 hours on long flights, car rides etc.
