Deep Vein Thrombosis

Blood clot formation in deep veins, usually in the legs

What is it?

Deep Vein Thrombosis (DVT) is a blood clot that forms in a deep vein, usually in the leg. DVT is serious because it can cause a pulmonary embolism (PE) — a potentially life-threatening complication where the clot breaks loose and travels to the lungs.

Symptoms

  • Swelling in the affected leg
  • Pain or tenderness in the leg
  • Warmth and redness over the affected area
  • Enlarged surface veins

Causes & Risk Factors

  • Immobility (long flights, bed rest)
  • Surgery or trauma
  • Certain medications (oral contraceptives)
  • Clotting disorders
  • Cancer
  • Pregnancy

Diagnosis

Compression ultrasound is the primary diagnostic tool. D-dimer blood test and CT pulmonary angiography are used to rule out pulmonary embolism.

Treatment Options

Anticoagulant medications (blood thinners)
Compression stockings
Thrombolysis (clot-dissolving medication)
Thrombectomy (clot removal)

When to Seek Medical Advice

Seek emergency care if you have shortness of breath, chest pain, or coughing up blood — these are signs of pulmonary embolism requiring immediate treatment.
