[Post-thrombotic syndrome: the forgotten complication of venous thromboembolism].

The post thrombotic syndrome (PTS) is the most common chronic complication of deep vein thrombosis (DVT), with a cumulative incidence of 20-50%. PTS is characterized by the occurrence of various signs and symptoms of chronic venous insufficiency in a limb previously affected by DVT. This condition significantly impairs quality of life and results in substantial burden to society. So far, treatment options are limited and strategies that prevent PTS occurrence are therefore of major importance. The present article critically reviews the definition, diagnosis, incidence, risk factors of PTS occurrence and treatment strategies for PTS.
