Portal vein Doppler exam performed 4hrs after ROSC on day 1. There is a biphasic portal vein profile with flow reversal. Maximum and minimum velocities are 13 and 5.76 cm/s, respectively. Pulse is 85 beats per minute (bpm). Portal vein pulsatility fraction is greater than 100 %. Ascites is present.

Bedside point of care ultrasound was remarkable for a moderately reduced biventricular function; a significantly dilated inferior vena cava and a high portal vein pulsatility fraction (Figure 1).
Portal vein Doppler exam on day 3. Maximum and minimum velocities are 22.3 and 9.98 cm/s, respectively. Pulse is 102 bpm. Portal vein pulsatility fraction is 59 %. Ascites is once again noted.

Repeat bedside portal vein assessment (Figure 2) showed a substantial decrease in portal vein pulsatility fraction.

Bedside portal vein assessment showed a biphasic portal vein pattern consistent with venous congestion (Figure 3). Significant improvement in symptoms, serum sodium levels (120 to 136 meq/L), and a decrease in the portal vein pulsatility fraction (Figures 3 and 5) was also seen.
Hepatic vein Doppler exam on day 1. Evidence of systolic flow reversal (green arrow).

Hepatic vein Doppler was also suggestive of volume congestion (Figure 4).
Portal vein Doppler exam on day 3. The pulse was 90 bpm. The pulsatility fraction was less than 20%.

Significant improvement in symptoms, serum sodium levels (120 to 136 meq/L), and a decrease in the portal vein pulsatility fraction (Figures 3 and 5) was also seen.
