Deep Vein Thrombosis, or DVT, is a blood clot in a deep vein. Deep veins are veins that travel deep in the body and are usually surrounded by muscle. Deep vein thrombosis is a more serious condition than superficial venous thrombosis, which is a blood clot in a superficial vein, because of the risk of a pulmonary embolsim (PE). A pulmonary embolism is a life threatening condition.
A pulmonary embolism can occur when the blood clot in a deep vein breaks off and travels to the lungs. Blood clots in superficial veins do not travel to the lungs so there is no risk of pulmonary embolism.
Deep Vein Thrombosis usually occurs in the legs and pelvis. However it can occur in any deep vein. Deep Vein Thrombosis in the upper arms is referred to as Paget-Schroetter disease.
What are the symptoms of Deep Vein Thrombosis?
If the clot is small you will probably never know you had it. The body will break it down naturally. If the clot is large you may exhibit these symptoms:
- Pain and/or tenderness. This may only be felt when walking/standing.
- Swelling, warmth in the swollen area
- Redness of the skin
- Chest pain during deep breaths
- Shortness of breath
How do I know if I have Deep Vein Thrombosis?
DVT can be hard to determine. If symptoms are present and you are at risk for developing deep vein thrombosis then you should see a doctor immediately. A pulmonary embolism is a good sign that you have DVT but you never want it to progress that far. An ultrasound may show a blood clot, but the only sure fire method is to undergo an intravenous venography procedure.
