The aim of this study was to assess the association of venous stasis and surgery to deep venous thrombosis in a tertiary hospital. The association of venous stasis and surgery with deep venous thrombosis was evaluated in patients at Hospital de Base, Faculdade de Medicina de São José do Rio Preto in the period from June 2007 to June 2008. Eightyâ€Âone patients (56.7% females and 43.2% males) were analyzed. Recent histories of immobilization or bed rest were reported in 16% of the cases and 9.8% had recently been submitted to surgical procedures. Venous stasis persists as a factor very closely related to deep venous thrombosis despite of prophylactic measures employed in hospitals.
