Figure 16. Infarct in a 56-year-old woman with hepatic artery thrombosis 9 days after orthotopic liver transplantation. US (top left) and CT (top right) images show a peripheral parenchymal infarct (*) in segment 6 of the liver. Doppler spectrum for the intrahepatic artery (bottom) shows an abnormal tardus-parvus waveform (arrow); this flow originates from collateral pathways.
