Persistance of residual vein thrombosis after an episode of deep vein thrombosis of the lower limbs and the risk of new cancer and cardiovascular disease

8531 Background: In patients with a first episode of idiopathic or provoked Deep Vein Thrombosis (DVT), the presence of Residual Vein Thrombosis (RVT), detected by UltraSonography (US) at the 3rd month from the index DVT, is an independent risk factor for developing recurrent Venous Thromboembolism (VTE) in the subsequent 2 years. Its absence can safely permit to stop Oral Anticoagulants (OA). At the present, it is unknown whether RVT may also identify patients at increased risk for developing cancer and/or cardiovascular disease (CD). In patients with previous DVT of the lower limbs, we conducted a prospective study for evaluating the correlation between RVT findings and the risk of new cancer and/or CD. Methods: Three hundred-forty-five patients, with a previous episode of idiopathic or provoked DVT, were evaluated; presence/absence of RVT was detected at the 3rd month of OA and patients managed consequently. In the present study, the incidence of VTE recurrence, cancer and new CD was evaluated in the s...
