International Clinical Practice Guidelines for Acute Deep Vein Thrombosis: A Comparative Review of Recommendations, Evidence Gaps, and Emerging Trends

Le résumé fourni par la source

Acute deep vein thrombosis (DVT) continues to represent a significant global contributor to morbidity and mortality. Although multiple international societies have published evidence-based clinical practice guidelines, important differences persist. This structured narrative review compares contemporary international guidance to identify areas of consensus, methodological divergence, evidence gaps, and priorities for future research. Recommendations were compared across diagnostic evaluation, anticoagulant selection, treatment duration, outpatient management, compression therapy, endovascular intervention, and special populations. Broad agreement was identified regarding clinical pretest probability assessment, D-dimer testing, compression ultrasonography, and direct oral anticoagulants as first-line therapy for most eligible patients with acute DVT. Clinically important differences remain, however, in the management of isolated distal DVT, anticoagulation duration, catheter-directed interventions, compression therapy, and selected high-risk populations. These discrepancies primarily reflect differences in publication timing, methodological frameworks, interpretation of emerging evidence, and healthcare-system context rather than fundamentally conflicting evidence. Contemporary international guidance therefore demonstrates substantial convergence on the core principles of acute DVT management while continuing to differ in areas supported by limited or evolving evidence. Future harmonization will require high-quality randomized trials, broader international collaboration, and the integration of precision medicine, validated risk-prediction models, biomarkers, and emerging anticoagulant strategies into guideline development.
