Profilassi antitrombotica nel paziente chirurgico: a che punto siamo? [Venous thromboembolism prophylaxis after general surgery: where are we now?]

Venous thromboembolism (VTE) is a frequent complication in patients undergoing major surgery, with the possibility of long-term disability or fatal outcome. The rationale of the thromboprophylaxis in all patients can be summarized in three points: 1) the VTE is common in some types of surgery; 2) the VTE can be fatal; 3) thromboprophylaxis is highly effective and safe and, besides these clinical benefits, leads to lower total costs of treatment without further diagnostic and a new shelter for treating venous thrombosis. The surgical patients may present at admission one or more risk factors for VTE, The effect of this risk is cumulative, it is important to stratify the risk and to established an adequate prophylactic strategy. Today there is a unanimous consensus that the low molecular weight heparins are both effective and safe in preventing VTE in surgical patients. Unanimously approved guidelines can help surgeons in making decisions regarding VTE prophylaxis.
