Post-thrombotic syndrome (PTS)

Consequential damage can also develop after treatment of thrombosis. In most cases, a thrombosis heals without complications.
However, if the venous valves in the affected vein section are damaged due to inflammatory processes, a chronic backflow congestion with decompensation of the venous system occurs as a consequence of the experienced thrombosis and a post-thrombotic syndrome (PTS) can develop.
In the case of about a third of patients, post-thrombotic syndrome can result after a deep thrombosis that without corresponding consistent further treatment can lead to increasing swelling of the leg, varicose vein formation, circulatory disorders of the skin and ultimately to the formation of crural ulcers.
