RESUMO
Venous thromboembolic disease (VTE) occupies an important place as a cause of morbidity and mortality in surgical patients in all specialties. Despite the existence of guidelines for thrombo prophylaxis in surgery, it is not clear due to the lack of current evidence, how to develop antithrombotic prophylaxis in varicose vein surgery and many questions arise when the surgeon is faced with a patient to be operated on. A comprehensive review of the literature was conducted to examine the evidence about the prevention of the venous thromboembolism in varicose veins surgery patients, and aims to guide the reader through questions that arise in daily practice, discussing the different scenarios presented in the literature for the choice of the most appropriate prophylaxis for each case. The lack of conclusive literature determines that risk should be individualized using available scales and other procedure-related factors, so that the type and duration of prophylaxis can be determined on a case-by-case basis.
