Causes
Risk Factors
- The risk factors for deep vein thrombosis (DVT) include: 1. A history of DVT. 2. Conditions or factors that make your blood thicker or more likely to clot than normal. Some inherited blood disorders (such as factor V Leiden) will do this. Hormone therapy or birth control pills also increase the risk of clotting. 3. Injury to a deep vein from surgery, a broken bone, or other trauma…
Signs and Symptoms
- The signs and symptoms of deep vein thrombosis (DVT) might be related to DVT itself or pulmonary embolism(PE). See your doctor right away if you have signs or symptoms of either condition. Both DVT and PE can cause serious, possibly life-threatening problems if not treated.
Diagnosis
- Your doctor will diagnose deep vein thrombosis (DVT) based on your medical history, a physical exam, and test results. He or she will identify your risk factors and rule out other causes of your symptoms. For some people, DVT might not be diagnosed until after they receive emergency treatment for pulmonary embolism(PE).
Treatment
- Doctors treat deep vein thrombosis (DVT) with medicines and other devices and therapies. The main goals of treating DVT are to: 1. Stop the blood clot from getting bigger 2. Prevent the blood clot from breaking off and moving to your lungs 3. Reduce your chance of having another blood clot
Prevention
- You can take steps to prevent deep vein thrombosis (DVT) and pulmonary embolism(PE). If you're at risk for these conditions: 1. See your doctor for regular checkups. 2. Take all medicines as your doctor prescribes. 3. Get out of bed and move around as soon as possible after surgery or illness (as your doctor recommends).
