Femoral Vein Pulsatility and Neurocognitive Disorder in Cardiac Surgery.

Background: Neurocognitive disorder and venous congestion are related in cardiac surgery. Femoral vein (FV) Doppler allows noninvasive assessment of venous congestion. This study aims to associate postoperative neurocognitive disorder in cardiac surgery with FV pulsatility.

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.

Purpose: Doppler ultrasound assessment of common femoral vein (CFV) flow could represent a simple, fast, and noninvasive technique to identify right ventricular dysfunction and venous congestion in patients undergoing cardiac surgery. Our primary objective was to determine the prevalence of abnormal CFV flow pulsatility before cardiac surgery. Secondary objectives included investigating its association with postoperative outcomes.
