Abstract

Post‑thrombotic syndrome (PTS) is the most frequent complication of deep vein thrombosis, and it can be detrimental to the quality of life of the affected patients. Once affected by this chronic condition, the patient’s treatment options are very limited, so preventive therapies are crucial. Currently, the prevention of PTS is hampered by the lack of unequivocally effective therapies. However, improved insight into pathogenesis of this condition acquired in recent years, including the central role of residual venous obstruction, could lead to a better application of existing therapies and identification of novel therapeutic targets. Plausible therapeutic agents include flavonoids and statins, while promising future agents include those that target leukocyte‑endothelial interaction. Moreover, differences in PTS risk were found to be partly explained by a tendency of patients to form clots that are less susceptible to lysis. Finally, identifying patients that are expected to benefit most from certain therapies is equally valuable for the success of future preventive strategies. This requires exploration of better risk stratification through machine learning techniques.
