Post-Thrombotic Syndrome: Pathophysiology, Clinical Implications, and Advances in Management

Area of Science:

• Vascular Medicine
• Thrombosis Research
• Clinical Outcomes

Background:

• Post-thrombotic syndrome (PTS) is a frequent complication following deep vein thrombosis (DVT), characterized by chronic venous insufficiency and hypertension.
• Despite its prevalence, PTS lacks standardized diagnostic criteria, leading to significant morbidity and healthcare burden due to its irreversible nature and limited management options.

Purpose of the Study:

• To review the current literature on the pathophysiology, diagnosis, and management of post-thrombotic syndrome (PTS).
• To highlight the need for improved prevention strategies, diagnostic tools, and evidence-based treatment protocols for PTS.

Main Methods:

• A comprehensive literature search was conducted using PubMed, Embase, and Google Scholar (1980-2025).
• Studies were selected based on relevance to PTS in adult patients and excluded non-English articles and those on other venous disorders.
• Selected articles were critically analyzed to summarize key findings and outcomes.

Main Results:

• Diagnosis of PTS is primarily clinical, with scales like Villalta and CEAP offering limited accuracy.
• Current management includes lifestyle changes, pharmacotherapy, compression, anticoagulation, and interventions like thrombolysis and stenting.
• Catheter-directed interventions show promise but have limitations; evidence for compression therapy is limited.

Conclusions:

• There are no definitive methods for preventing or effectively treating established PTS.
• Preventing DVT is key to reducing PTS incidence.
• Urgent development of comprehensive prevention strategies, improved diagnostics, and evidence-based treatments is essential for optimizing patient outcomes.
