Abstract

Background: Deep vein thrombosis  is a silent yet dangerous condition caused by various factors, including trauma, lower limb fractures, and internal medical conditions. Surgical interventions for major lower limb fractures increase the risk of developing deep vein thrombosis. Objectives: To determine the prevalence of deep vein thrombosis and investigate some risk factors associated with deep vein thrombosis in patients with major lower limb fractures. Methods: This prospective descriptive study was conducted on patients with major lower limb fractures diagnosed and treated at the Orthopedic Department of Gia Dinh People's Hospital. All patients were assessed using the Caprini risk score and underwent Doppler ultrasound of the lower limb veins at admission and post-surgery. Results: Among 90 patients with major lower limb fractures, the deep vein thrombosis incidence was 18.8% (17/90 patients). Hypertension (15/17 cases), length of hospital stay (p= 0.009), and femur fractures (15/17 cases) were statistically significant factors associated with deep vein thrombosis occurrence. Conclusions: The risk of deep vein thrombosis in patients with major lower limb fractures is significant and increases with underlying conditions, hospital stay duration, and fracture location. Therefore, prophylactic deep vein thrombosis treatment before and after surgery is essential.
