DVT Overview

DVT occurs when a blood clot forms in a deep vein, usually in the lower limbs. A complication of DVT, pulmonary embolism, can occur when a fragment of a blood clot breaks loose from the wall of the vein and migrates to the lungs, where it blocks a pulmonary artery or one of its branches.

  • Up to 2 million Americans are affected annually by DVT
  • Of those who develop PE, up to 300,000 will die each year
  • More people die in the United States from PE than breast cancer and AIDS combined
