WebApr 14, 2024 · The venous excess ultrasound (VExUS) score is a multi-organ Doppler approach to assess venous congestion. Despite growing use of VExUS in research and clinical practice, other veins can be visualized to assess for venous hypertension, which may overcome acquisition barriers of the VExUS exam. Web2 days ago · Pulsed wave Doppler waveforms of the portal and splenic venous flow were obtained as described in a previous study. 5 The pulsatility index of both veins was calculated as follows: pulsatility index (%) = (maximal velocity – minimal velocity)/maximal velocity ( Figure 1 ). 5 The second ultrasound measurement was performed in the same …
