DVT occurs when your blood thickens in a clump that becomes solid, forming a clot. It requires prompt attention; if you develop a clot and a piece of it breaks off, it could travel to one of your lungs and make breathing difficult or even cause death.
Inactivity such as after a major operation or during a flight, Cancer and certain other diseases and genetic conditions, called hypercoagulable states, that cause your blood to clot more easily, and some medications.
DVT is usually treated with medication.
- Blood thinners, also known as anticoagulants, are the most common medicines used for treating DVT. They prevent blood clots from getting larger by decreasing your blood\'s ability to clot.
Blood thinners can be taken as a pill, as an injection or intravenously (through an IV). Blood thinners can increase your chance of bleeding, so careful follow-up with your vascular surgeon is necessary.
- Thrombolytic therapy is sometimes used to quickly dissolve a blood clot, especially if the clot is large and causing severe symptoms.
- An IVC filter placed inside the inferior vena cava, one of the largest veins in the body, may be an option. The filter does not stop a blood clot from forming, but can prevent a large clot from entering your lungs.
