International audience. The post-thrombotic syndrome (PTS), which refers to chronic clinical manifestations of venous insufficiency after a deep vein thrombosis (DVT), is a frequent occurrence. Because treatment options for PTS are limited, its management mainly relies on the prevention of its occurrence after DVT. Among identified predictors of PTS, extensive proximal location of DVT directly modifies the treatment of DVT because of the possibility of performance of complementary endovascular techniques. The association between poor international normalized ratio control and subsequent PTS should encourage physicians to perform frequent and regular international normalized ratio monitoring of patients receiving vitamin K antagonists. Other identified PTS risk factors are ipsilateral DVT recurrence, older age, pre-existing primary venous insufficiency, obesity, and residual venous obstruction, but these are less amenable to therapy. Because of their potential therapeutic implications, identification of biomarkers that are predictive of PTS such as markers of inflammation is crucial and such research is ongoing.
