Vascular Complications After Venoarterial Extracorporeal Membrane Oxygenation Support: A CT Study
Authors' conclusion
Vascular complications related to venoarterial ECMO cannula are common after ECMO implantation. CT allows early detection of complications after weaning and impacts patient management.
Study context
- Population
- Adults successfully weaned from venoarterial extracorporeal membrane oxygenation (ECMO), January 2021–January 2022underwent CT
- Participants
- 109 participants
- Outcome
- Frequency of vascular complications related to ECMO cannula (CT within 4 days after weaning)
Methodological detailsobservational, two ICUs, tertiary referral academic hospital
- Observational
- Two ICUs
- Tertiary referral academic hospital
