OBJECTIVE: To identify and compare the rates of cannula-associated deep vein thrombosis (CaDVT) in patients on venovenous extracorporeal membrane oxygenation (VV-ECMO) who receive systemic anticoagulation (AC) and those who do not receive AC.
DESIGN: Retrospective observational study.
SETTING: Tertiary academic medical center.
PARTICIPANTS: Consecutive patients who successfully have been decannulated from VV-ECMO for treatment of refractory acute respiratory distress syndrome between 2017 and 2022.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: After decannulation of ECMO, a duplex sonograph was performed on the cannulation sites to determine the incidence and characteristics of cannula-related thrombosis. Thrombosis was classified as occlusive or nearly occlusive. Ninety-four of 161 patients were weaned from VV-ECMO. Nineteen patients who were placed on VV-ECMO due to COVID-19 were excluded. Twenty-seven of 52 patients (52%) who did not receive AC were identified to have thrombus. Twelve of 23 patients (52%) who received AC were identified to have thrombus. Patients who received AC required more blood products during the ECMO run and required longer support on VV-ECMO.
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. Routine post-decannulation screening for DVT is recommended due to the high incidence of CaDVT.
