Prevalence of abnormal common femoral vein pulsatility on Doppler ultrasound in patients undergoing cardiac surgery and its association with adverse events: a prospective cohort study
Authors' conclusion
Abnormal CFV flow pulsatility occurred in 20% of patients before cardiac surgery and was associated with a higher rate of major postoperative complications, longer durations of postoperative support and care, and a longer cumulative time of persistent organ dysfunction after surgery.
Study context
- Population
- Adults undergoing cardiac surgery with CPB
- Participants
- 150 adults
