Blood Clots
(Deep Venous Thrombosis)

Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling, but may occur without any symptoms. DVT is a feared complication of venous disease because it can lead to a pulmonary embolus, a clot in the lung that can be deadly.

  • Sudden onset of pain and swelling in your leg (most commonly in the back of your calf or your entire thigh)
  • Usually, the painful part of your leg is also swollen
  • Pain and/or swelling comes on abruptly and generally does not go away even after a few days

Risk Factors

  • Long plane or car rides
  • Immobility (after an operation or injury)
  • Obesity
  • Sedentary lifestyle
  • Pregnancy
  • Orthopedic or gynecological procedures
  • Some genetic factors (hypercoagulable syndromes)
  • Dehydration
  • Cancer


If you suspect you may have a blood clot, it is very important to go to your regular doctor and get an ultrasound of your leg. If this test is “normal” but the swelling or pain persists, then you should go see a vascular surgeon, as more testing (such as CT scan or specialized ultrasound) may need to be done. This is quite important to do quickly, as some treatments only work if they are done within a week of the development of symptoms.

If you are diagnosed with a DVT, you should be treated with blood thinners immediately. The role of blood thinners is not to actually “dissolve” the clot in your leg, but rather to prevent it from traveling to your lung and causing a Pulmonary Embolus. The blood thinners also work to prevent the clot from becoming more extensive.

If this is your first blood clot, you should be treated for 6 weeks to 3 months with blood thinners depending on why the blood clot occurred. If there is not a clear reason for the blood clot, it is important to dig deeper and find the underlying cause.
