Primary Outcome Measures

Name	Time	Method
Main Objective: to characterize the pharmacokinetic /pharmacodynamic profile of a 7-day treatment with oral rivaroxaban ;Secondary Objective: •to assess the incidence of major bleeding and clinically relevant non-major bleeding•to assess the incidence of symptomatic recurrent thromboembolism and •to assess asymptomatic deterioration in the thrombotic burden on repeat imaging;Primary end point(s): PK/PD modeling, using population approaches will be used to describe the pharmacokinetics of rivaroxaban, and to relate anticoagulant parameters of rivaroxaban with plasma concentrations. ;Timepoint(s) of evaluation of this end point: After last patient. last visit

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): 1. The occurrence of recurrent venous or arterial thromboembolism and asymptomatic deterioration in thrombotic burden will be summarized.2. All safety analyses will be performed on the safety population. Bleeding events observed later will be described separately. Individual listings of major and clinically relevant non-major bleeding will be provided. 3. The occurrence of recurrent venous or arterial thromboembolism and asymptomatic deterioration in thrombotic burden;Timepoint(s) of evaluation of this end point: 1. After LPLV <br> 2.The analysis will primarily focus on bleeding that occurred during or within 2 days after stop of rivaroxaban<br>
