Deep
Deep vein thrombosis (DVT) is a medical condition that occurs when a blood clot forms in one of the deep veins of your body, usually in your legs, but sometimes in your arm. The main cause of DVT is a condition called venous stasis, in which blood does not flow around the body as well as it should, leading to clots forming in the veins.
Causes[edit | edit source]
The main cause of DVT is a condition called venous stasis, in which blood does not flow around the body as well as it should. This can be due to a number of factors, including:
- Being immobile for long periods of time, such as during a long flight or car journey
- Having certain medical conditions or treatments that make your blood more likely to clot, such as cancer or hormone therapy
- Having had a DVT before
- Being overweight or obese
Symptoms[edit | edit source]
The symptoms of DVT can include:
- Swelling in the affected leg or arm
- Pain or tenderness in the leg or arm, often starting in the calf and can feel like cramping or soreness
- Red or discolored skin on the leg or arm
- A feeling of warmth in the affected leg or arm
Diagnosis[edit | edit source]
DVT can be diagnosed using a variety of tests, including:
- A Doppler ultrasound, which uses sound waves to create a picture of the blood flow in your veins
- A venogram, which involves injecting a special dye into your veins so they can be seen on an X-ray
- A D-dimer test, which can detect pieces of blood clot that have been broken down and are loose in your blood
Treatment[edit | edit source]
Treatment for DVT usually involves medications to prevent the blood clot from getting bigger and to stop new clots from forming. This can include:
- Anticoagulant medications, such as warfarin or heparin
- Thrombolytic therapy, which involves injecting a drug into the vein to dissolve the blood clot
- In some cases, surgery may be needed to remove the blood clot
Prevention[edit | edit source]
There are several ways to help prevent DVT, including:
- Regular exercise
- Staying hydrated
- Avoiding sitting still for long periods of time
- Wearing compression stockings if you're at high risk of DVT
