Macro- and microcirculation patterns of intrahepatic blood flow changes in patients with hereditary hemorrhagic telangiectasia

Figure 5 Arteriovenous and arterioportal hepatic malformation (shunt) in a 62-year-old woman. Color coded Doppler sonography and Power Doppler images. A: Intrahepatic arterial hypervascularization with tortuos hepatic artery and aliasing in segment IV (central), V and VIII of the liver as well as obvious presence of "color spots". Enhanced mean diameter of the hepatic artery (7.8 mm) intrahepatic and increased peak systolic velocity (123.8 cm/s) and end-diastolic velocity (61.4 cm/s) as well as decreased RI (0.5); B: Image of the portal vein of the same patient, illustrating arterioportal shunt formation and signs of portal hypertension but without elevation of the mean diameter. Caselitz-Kriteria: 2 Major + 4 Minor; Buscarini grade 3; presence of "color spots" in peripheral regions.
