Microvesicle Production After Acute Trauma and Its Clinical Impact on Venothromboembolism
This study is ongoing, but not recruiting participants.

The purpose of this research study is to look at how trauma affects the ability of blood to clot. The blood of people who suffer a traumatic injury can under-clot or over-clot, and this research study will look at blood drawn from people after they suffer a traumatic injury to see how well their blood clots.
||Observational Model: Case Control
Time Perspective: Prospective
||Microvesicle Production After Acute Trauma and Its Clinical Impact on Venothromboembolism
Primary Outcome Measures:
- Estimate the distribution over time of procoagulant Microvesicles (MVs) concentration by cell of origin and endogenous thrombin potential (ETP). [ Time Frame: 6 months ] [ Designated as safety issue: No ]
- Determine the cumulative incidence of Venothromboembolism (VTE) within three months after major trauma and test the distribution of procoagulant MV concentration and endogenous thrombin generation potential over time as potential predictors of VTE. [ Time Frame: 4 years ] [ Designated as safety issue: No ]
