English: Figure 2. A 2-year-old male who developed VOD/SOS after HCT for acute myelogenous leukemia. (A) Color Doppler ultrasound images from an examination performed 16 days after HCT showing flow in the main portal vein away from the liver parenchyma (arrow). (B) Spectral Doppler image from the same patient showing flow away from the liver, with a peak velocity of 20.7 cm/s. (C) Spectral Doppler image from the same patient showing elevated peak systolic velocity in the proper hepatic artery causing an elevated resistive index of .83. (D) Spectral Doppler image from the same patient showing relatively constant flow in the left hepatic vein with lack of normal respiratory and cardiac variation. VOD/SOS, veno-occlusive disease/sinusoidal obstruction syndrome; HCT, hematopoietic cell transplantation.
