Deep Vein Thrombosis
Urgent
Deep vein thrombosis is a blood clot that forms in a deep vein, most commonly in the leg. It can cause swelling, pain, warmth, tenderness, or a change in the appearance of the affected limb, although some people have few or no noticeable symptoms. A major concern is pulmonary embolism, which can occur when part of the clot breaks away and travels to the lungs. Sudden shortness of breath, chest pain, coughing up blood, or fainting requires urgent medical attention.

When to Seek Medical Attention
Deep vein thrombosis requires prompt medical assessment because a blood clot can potentially travel to the lungs. Seek urgent care for new swelling, pain, warmth, or redness in one leg, especially when symptoms are unexplained. Emergency medical attention is required for sudden shortness of breath, chest pain, coughing up blood, fainting, severe dizziness, or rapidly worsening symptoms.

Overview

Causes
Deep vein thrombosis develops when conditions favor formation of a blood clot inside a deep vein. Reduced blood flow from prolonged immobility, increased tendency of the blood to clot, or injury to the inner lining of a blood vessel can all contribute. Surgery, hospitalization, serious illness, cancer, pregnancy, certain medicines, inherited clotting disorders, and prolonged travel can increase the likelihood of clot formation. Several risk factors may occur together in the same person.
Risk Factors
Risk increases with prolonged immobility, recent surgery, hospitalization, serious illness, cancer, pregnancy, use of estrogen-containing medicines, previous DVT or pulmonary embolism, inherited clotting disorders, obesity, and increasing age. Long-distance travel involving prolonged sitting can contribute, particularly when other risk factors are present. Smoking and certain chronic medical conditions may also contribute to overall clotting risk.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on symptoms, physical findings, and assessment of the likelihood of DVT. Compression ultrasonography is commonly used to examine blood flow and detect a clot in the deep veins. A D-dimer blood test may help exclude DVT in selected people when the clinical probability is low or intermediate. If DVT is strongly suspected, treatment decisions and further testing are guided by the clinical assessment and initial test results.
Prevention
Key Prevention Tips
Regular movement can help reduce blood stasis during prolonged sitting or bed rest
During long journeys, periodically walk or move the legs when it is safe to do so
After surgery or serious illness, early mobilization should follow the healthcare team's recommendations
People with a high risk of thrombosis may be prescribed preventive anticoagulant treatment or mechanical measures
Maintaining a healthy weight, avoiding smoking, and managing medical conditions can also reduce overall cardiovascular and clotting risk
Prevention Guidance

After surgery or serious illness, early mobilization should follow the healthcare team's recommendations. People with a high risk of thrombosis may be prescribed preventive anticoagulant treatment or mechanical measures.

Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
