Cannula-Associated Deep Vein Thrombosis After Venovenous Extracorporeal Membrane Oxygenation in Patients with and Without Systemic Anticoagulation
Authors' conclusion
This study showed a high incidence of cannula-related venous thrombosis after VV-ECMO decannulation. Surprisingly, the incidence of CaDVT in anticoagulation-free patients was the same as in patients requiring anticoagulation. Anticoagulated patients required longer support on VV-ECMO and required more transfusions.
Study context
- Population
- Consecutive patients successfully decannulated from VV-ECMO for refractory ARDS, 2017–2022; COVID-19 patients excluded94 weaned
- Participants

- Exposure
- Systemic anticoagulation vs no anticoagulation during VV-ECMO
- No anticoagulation (AC)n = 52reference
- ACn = 23

Main finding
As reported in the abstract
Observational data: associations, not effects.
Further findings
Blood products and duration of VV-ECMO support
- AC patients required more blood products during the ECMO run and longer VV-ECMO support
