Deep vein thrombosis (DVT) and pulmonary embolism (PE) stand as the primary manifestations of venous thromboembolism (VTE) [1-3]. Nonetheless, the absence of national surveillance systems for VTE leaves the exact number of affected individuals unknown [4]. Studies based on clinical-administrative and hospital database suggest an estimated annual incidence of VTE ranging from 1 to 1.8 per 1000 inhabitants in Europe. Although the presentation varies across studies, they concur that over 50 % of VTE cases manifest as isolated DVT, while the remainder present as PE (with or without DVT) [5].
