Blood Clot in the Legs (cont.)

Deep Vein Thrombosis Prognosis

Most DVTs resolve on their own. If a PE occurs, the prognosis can be more severe.

  • About 25% of people who have a PE will die suddenly, and that will be the only symptom.
  • 10 to 30% of people with DVT/PE will die within 1 month of diagnosis.

If an individual has had one deep vein thrombosis, they are more likely than the average person to have another deep vein thrombosis.

  • The CDC estimates 33% of people with DVT/PE will have a recurrence within 10 years.
  • Recurrence of DVT is more common in patients with risk factors such as cancer or inherited blood-clotting problems. Recurrence is less common in patients who have short-term risk factors, such as surgery or temporary inactivity.
  • Closely follow the prevention instructions from the doctor.
  • Anticoagulant therapy lowers the death rate from pulmonary embolism significantly.
