Aspirin Versus Enoxaparin for Deep Vein Thrombosis Prevention After Orthopedic Surgery: A Review of Efficacy and Safety

Abstract

Deep vein thrombosis (DVT) is a significant complication following orthopedic surgery. This review evaluates the comparative efficacy and safety of aspirin and enoxaparin for DVT prophylaxis in this patient population. A comprehensive literature search identified relevant randomized controlled trials (RCTs), retrospective studies, and systematic reviews with meta-analyses comparing these two medications. The findings regarding aspirin's efficacy compared to enoxaparin are mixed. While some studies suggest comparable effectiveness in preventing DVT, others indicate a potential advantage for enoxaparin. However, aspirin offers advantages in terms of ease of administration (oral medication), potentially lower bleeding risk, and potentially improved patient satisfaction and adherence. Drawing definitive conclusions is limited by heterogeneity among the included studies. Variations in patient populations, surgical procedures, and follow-up durations hinder a more conclusive comparison. Additionally, the potential for bias in some studies necessitates a cautious interpretation of the results. This review also has limitations, as it does not explicitly appraise the methodological quality of each included study. Despite these limitations, aspirin emerges as a potentially viable alternative, and perhaps even an excellent option, for DVT prophylaxis after orthopedic surgery in specific scenarios. However, limitations within the current evidence necessitate further research with standardized protocols and rigorous methodological evaluation. Individualized approaches that consider patient-specific risk factors and surgical procedures are crucial. If future research confirms aspirin's efficacy and safety profile, its ease of use and potential benefits could lead to it becoming a preferred option for DVT prophylaxis.
