Abstract

Travel-related thrombosis (TRT), encompassing deep vein thrombosis (DVT) and pulmonary embolism (PE), poses a significant health risk associated with long-haul travel. Prolonged immobility, dehydration, and cabin pressure changes during flights contribute to venous stasis, hypoxia, and hypercoagulability, collectively increasing the risk of venous thromboembolism (VTE). While the absolute risk of TRT is relatively low in the population overall, it rises significantly among high-risk groups, including individuals with a history of VTE, thrombophilia, pregnancy, or recent surgery. This review explores the epidemiology, pathophysiology, clinical presentation, and diagnostic evaluation of TRT while highlighting the importance of early recognition and prevention. Risk assessment models can provide guidance for identifying at-risk travelers. Preventive strategies include pharmacological prophylaxis with low-molecular-weight heparin (LMWH) for high-risk individuals and nonpharmacological measures such as compression stockings, intermittent pneumatic compression, mobility exercises, and hydration. Guidelines from international societies recommend tailored interventions based on individual risk profiles, as randomized controlled trials are scarce. Given that long-haul travel dramatically expands, this review critically analyzes the available TRT management strategies in various clinical settings, aiming to increase awareness of this global health issue.
