Brief Summary

The risk of venous thromboembolism (VTE) is very high in trauma patients, secondary to tissue injury, venous status from immobilization, and thrombophilia. As such, early initiation of VTE prophylaxis is essential in this population. The competing risks of life threatening hemorrhage and VTE need to be considered very carefully. Potential approaches to VTE prophylaxis include pharmacologic means, and mechanical devices. For patients unable to receive pharmacologic VTE prophylaxis, retrievable inferior vena cava filters (rIVCFs) may be placed until low molecular weight heparin (LMWH) can be initiated, as per guidelines such as Eastern Association for the Surgery of Trauma The investigators propose a feasibility study to determine whether or not our center can insert rIVCFs in at-risk trauma patients expeditiously enough to cause a meaningful reduction in the time they are left unprotected to PE.

Outcome Measures

Primary Outcomes (1)

  • Time left unprotected to venous thromboembolism

    time left unprotected to pulmonary embolism two weeks post arrival to hospital defined as: time point from arrival to LHSC to two weeks after, measured in hours where-in patient either has no rIVCF in situ, or has no regular low molecular weight heparin (LMWH) on board. missed doses of LMWH \> 2 hours within planned administration time will count toward primary outcome. If LMWH is held for operative intervention, time left held \> 24 hours post previous dose will count toward the primary outcome.

    two weeks post trauma

Secondary Outcomes (6)

  • Venous Thromboembolism

    in hospital (up to one year)

  • Mortality

    In Hospital (up to one year)

  • Filter Feasibility Outcome: Time to filter insertion

    hours to weeks, up to one year

  • Filter Feasibility Outcome: Time to filter removal

    hours to weeks, up to one year

  • Filter Feasibility Outcome: Filter retrieval rate

    hours to weeks, up to one year

  • +1 more secondary outcomes

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • consecutive age adult trauma patients who are:
  • Deemed unable to receive medial VTE prophylaxis within 72 hours post injury based on traumatologists' suspicion of increased bleeding risk, peri-spinal cord bleeding risk, or need for multiple surgical interventions.
  • AND
  • have at-least on of the following high risk VTE injuries as per EAST Guidelines:
  • severe closed head injury (GCS 8 or less upon presentation)
  • incomplete spinal cord injury with paraplegia or quadriplegia
  • complex pelvic fracture with associated long bone fracture(s)
  • multiple long bone fractures

You may not qualify if:

  • Patients not expected to survive for at least 72 hours post trauma
  • Patients with known uncorrectable coagulopathy
  • Patients known to be unable to receive a rIVC filter as part of this trial (for anatomical reasons or standard contraindication for device insertion)
  • Known active venous thromboembolic disease
  • Pregnancy
