Deep vein thrombosis is a blood clot in one of the deep veins, usually in the leg. The danger is that part of it can travel to the lungs, which is an emergency.
Symptoms
- Swelling, usually of one leg.
- Pain or tightness in the calf.
- Warmth or redness of the skin.
Who is most at risk?
- After major surgery, especially orthopaedic operations.
- Long periods of immobility, such as bed rest or long journeys.
- Pregnancy, after childbirth, and some hormonal medications.
- Cancer and some inherited clotting disorders.
Diagnosis and treatment
Diagnosis is made by Doppler of the leg veins. Treatment is mainly anticoagulant medication for a period set by the doctor; in selected cases a catheter is used to dissolve or remove the clot. Follow-up reduces long-term complications such as leg swelling and skin changes.
Prevention on long journeys
- Move your feet and ankles regularly while seated.
- Get up and walk every hour or two if possible.
- Drink enough water.
- If you are at higher risk, ask your doctor before travelling about compression stockings or preventive medication.
