Examining the controversies in venous thromboembolism prophylaxis for vascular surgery patients: A critical review

Abstract

BackgroundVenous thromboembolism (VTE) is a significant concern in vascular surgery due to its potentially severe consequences. Effective prophylactic measures are essential to minimize the risks associated with VTE. However, considerable controversy remains regarding the optimal strategies for VTE prevention in patients undergoing vascular procedures. MethodsThis review critically analyzes key clinical research, guidelines, and expert opinions to explore the advantages and limitations of various VTE prophylaxis approaches. The pharmacological and mechanical methods are explored, with a focus on balancing the risk of VTE against the potential for bleeding complications, particularly in high-risk patients. ResultsThe review addresses controversial issues such as the choice of anticoagulants, dosage, timing, and duration of prophylaxis. The lack of consensus in existing guidelines and the variability in clinical practice regarding VTE prevention in vascular surgery patients is highlighted. The role of patient-specific risk factors, including the use of intraoperative anticoagulation and bleeding risks, is also examined. ConclusionThis review provides a comprehensive evaluation of VTE prophylaxis strategies in vascular surgery, emphasizing the need for individualized, evidence-based approaches. Clarifying these controversies is crucial for optimizing patient outcomes and minimizing both thrombotic and hemorrhagic complications.
