The Post-Thrombotic Syndrome (PTS) is a frequent (40%) long-term complication of deep vein thrombosis (DVT, “blood clot”), and often causes one or more of these leg problems on a daily basis:

  • swelling
  • aching or pain
  • sensation of heaviness
  • fatigue
  • changes in skin color
  • skin breakdown causing open sores (“ulcers”)
