Deep vein thrombosis is a blood clot in a deep vein, usually in the leg. Its danger lies in part of it travelling to the lungs, and in long-term complications such as leg swelling and skin changes.
Symptoms
- Swelling, usually of one leg
- Calf pain or tightness
- Warmth or redness of the skin
Causes & risk factors
- After major surgery, especially orthopaedic
- Long immobility or long-haul travel
- Pregnancy, post-partum and some hormonal drugs
- Cancer and inherited clotting disorders
Diagnosis
Diagnosis is by venous Doppler of the leg, with blood tests in some cases to look for a cause.
Treatment options
Anticoagulation
The mainstay of treatment, for a duration set by the doctor according to the cause.
Catheter-directed thrombolysis or thrombectomy
In selected cases, especially large clots in the pelvic and thigh veins.
Compression stockings
To help reduce swelling and long-term complications.
After treatment
Most patients improve gradually with treatment; follow-up matters to set the anticoagulation period and lower the risk of complications.
