Deep Vein Thrombosis - Symptoms

Only about half of the people with deep vein thrombosis have symptoms. The symptoms may include:

  • Swelling of the leg
  • Pain or tenderness in the leg, usually in one leg and may be felt only when standing or walking
  • Increased warmth in the area of the leg that is swollen or in pain
  • Changes in skin colour or redness

Symptoms of pulmonary embolism include chest pain when taking a deep breath, rapid pulse, fainting, shortness of breath and coughing up of blood. Blood clots that remain lodged in the leg can result in pain and swelling.

It is important to see a doctor right away if you have symptoms of deep vein thrombosis or pulmonary embolism. Deep vein thrombosis can cause very serious complications if not treated.

Deep Vein Thrombosis - Causes and Risk Factors

Risk factors for DVT include poor blood flow and hypercoagulable states (a condition in which there is an abnormal increased tendency toward blood clotting). Conditions that puts patients at high risk for DVT include spinal cord injury, major trauma, major general surgery. The use of chemotherapy, oral contraceptive therapy, hormone replacement therapy and paralytic stroke may also increase the risk of DVT. Other conditions that confer risks include obesity, bed rest for more than three days, and immobility due to sitting and varicose veins.

Deep Vein Thrombosis - Diagnosis

​DVT is diagnosed via an ultrasound scan of the veins of the legs. The ultrasound will demonstrate if blood flow is abnormal through the vein.
