Figure 3a. Hepatic artery thrombosis in a 45-year-old man with worsening results on liver function tests 8 days after orthotopic liver transplantation for alcoholic cirrhosis. (a) Subcostal oblique color Doppler image of the right hepatic lobe shows avascular cystic spaces within the hepatic parenchyma, which represent infarcts. Flow is demonstrated in the adjacent hepatic veins. No hepatic artery flow was seen at the porta hepatis or anywhere in the liver on color or spectral Doppler images. (b) Corresponding contrast material-enhanced CT image shows the infarcts.
