Residual Vein Thrombosis (RVT) to Assess Optimal Management of DVT: DACUS Study6

Slide 14

June 2011

Another tool that can be used for risk stratification is the presence or absence of residual vein thrombosis assessed by ultrasound and this is the study that was assessed in the DACUS trial. These investigators took 250 patients, treated them with warfarin for at least 3 months and then assessed residual thrombus by ultrasound. If there was residual thrombus, then they randomized patients either to resume warfarin or to stop warfarin; if there was no residual thrombus then they simply stopped warfarin therapy.
