Deep venous thrombosis is a quite frequent pathology with a high degree of morbidity and death-rate. Two are the main problems of this disease: the risk of pulmonary embolism and outcome of a post-thrombotic syndrome, leading patients to infirmity. The patients max exposed to the risk of deep venous thrombosis are the surgical ones: the authors, with a retrospective study on 480 surgical patients, examine the risk factors mostly related with the onset of deep venous thrombosis.
