A Multi-centre Trial of Vena Cava Filters in Severely Injured Patients

Ho et al. N Engl J Med 2019; 381:328-337
DOI: 10.1056/NEJMoa1806515

Problem –

  • 18% of trauma patients develop Proximal DVTs (without anticoagulation)
  • 11% of patients develop PE
  • 37% of all major PEs occur in first 4 days following trauma
  • Fatal PE – less common (0.4-42%)
  • 12% of all major trauma patients half of this may be preventable 
  • 1-3 days of delay in commencing DVT prophylaxis  3x increased risk of developing DVT 
  • Prophylactic anticoagulation – 13x increased risk of haematoma (TBI)
  • Data from EPOTBI – 43% of patients don’t receive DVT prophylaxis for 1st 7 days 

Hypothesis –

Early placement (<72hrs) of IVC filters in severely injured trauma patients with C/I to prophylactic anticoagulation reduces the risk of symptomatic PE.
