Meta-analyses of sulodexide and other drugs in prevention and treatment of post-thrombotic syndrome.

Post-thrombotic syndrome (PTS) is a common chronic complication of deep vein thrombosis. Elastic compression (ECS) is the common pillar for PTS prevention and treatment, while the pharmacological approach for PTS includes direct oral anticoagulants (DOACs) and venoactive drugs (VADs) for prevention and treatment, respectively. Sulodexide can be used both in long-term prevention and in the treatment of PTS. To better understand the efficacy of the main drugs used in the prevention (sulodexide or DOACs) and treatment of PTS (sulodexide or VADs), pairwise meta-analyses of observational studies and RCTs were conducted.
