What is VExUS?

VExUS is venous excess ultrasound grading system intended to quantify systemic venous congestion, which is particularly important in patients with tenuous fluid volume status (e.g. those with right sided heart failure). It involves using Doppler ultrasound of the hepatic, portal and intra-renal veins as an adjunct to inferior vena cava assessment and better demonstrates how the organs are ‘feeling’ in terms of congestion. Other advantage is that these Doppler waveforms can be used to monitor the efficacy of decongestive therapy. Following lecture gives an overview of this topic.
