Post-Thrombotic Syndrome (PTS)

Source updated: July 12, 2022 1 min read

Post-thrombotic syndrome is a condition that can happen to people who have had a deep vein thrombosis (DVT) of the leg. The condition can cause chronic pain, swelling, and other symptoms in your leg. It may develop in the weeks or months following a DVT.

How is PTS diagnosed?

There is no gold standard test to diagnose post-thrombotic syndrome (PTS). The diagnosis is normally made by:

  • Reviewing a patient’s history of deep vein thrombosis (DVT) and current symptoms
  • Examining the leg
  • Sometimes supplementing this information with an ultrasound

An ultrasound doesn’t confirm the diagnosis, but it can help experts better understand if there are factors that might be contributing to PTS, such as a blocked vein or valve damage from the blood clot.

Talk to your doctor if you’ve had a DVT and are still experiencing symptoms after several weeks or months. They may refer you to a specialist, such as a vascular surgeon, for further evaluation.
