What is Post-Thrombotic Syndrome (PTS) and is it treatable?

PTS can occur in 30-50% of people after a DVT. It is a result of venous hypertension and inflammation associated with venous obstruction and/or reflux. It can lead to leg heaviness, swelling, varicosity, itching, skin pigmentation and ulceration. It’s a chronic condition. PTS can be more severe in cases of recurrent DVT, obesity, or if occurring higher up in the leg. While it is not curable, it can, in cases, be treated by minimally invasive techniques aimed to reduce venous obstruction. Research suggests that PTS may also be prevented in many cases by prompt catheter-based removal of clot if a DVT occurs.
