Deep Vein Thrombosis
A blood clot in a deep vein, usually in the leg, which can be life-threatening if it travels to the lungs.
Overview
Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, most commonly in the legs. The clot can partially or completely block blood flow, causing pain and swelling. The most serious complication is a pulmonary embolism — when part of the clot breaks off and travels to the lungs, which can be fatal. DVT can occur after surgery, prolonged immobility, or in people with certain clotting disorders.
Symptoms
Common Symptoms
- Swelling in one leg (usually the calf or thigh)
- Pain or tenderness in the affected leg
- Warmth in the area of the clot
- Red or discolored skin
- Leg pain that worsens when bending the foot
- Some DVTs have no symptoms
Emergency: Sudden shortness of breath, chest pain, or coughing blood may indicate a pulmonary embolism — call 911 immediately.
Diagnosis
Diagnosis typically involves clinical evaluation, medical history, blood tests, and appropriate imaging studies. A healthcare provider will assess symptoms, order relevant laboratory work, and may refer to a specialist for confirmation.
Treatments
Treatment depends on the underlying cause and severity. Options may include medication, lifestyle modifications (diet, exercise, stress management), and ongoing monitoring. Always work with a qualified healthcare provider to develop an appropriate treatment plan.
