Abstract:
Objective To observe contrast-enhanced ultrasound(CEUS)manifestations of nontumorous intrahepatic vascular shunts.Methods Data of 11 patients with intrahepatic vascular shunts were retrospectively analyzed,including 3 cases of intrahepatic arteriovenous shunts,3 cases of hepatic arterioportal shunts,1 case of intrahepatic arterioportal shunt complicated with intrahepatic arteriovenous shunt and 4 cases of intrahepatic portosystemic shunts.The conventional ultrasound and CEUS manifestations were observed.Results In 3 cases of intrahepatic arteriovenous shunts and 3 cases of hepatic arterioportal shunts,CEUS showed early enhancement of draining veins,early enhancement of local liver parenchyma without washout,while conventional ultrasound showed partial shunts in 2 cases with continuous enhancement showed on CEUS.The findings of 1 case of intrahepatic arterioportal shunt complicated with intrahepatic arteriovenous shunt were similar to the above two.Among 4 cases of intrahepatic portosystemic shunts,conventional ultrasound displayed all shunts,continuous enhancement of the draining hepatic vein and shunts were observed with CEUS,and transient low enhancement of local liver parenchyma were noticed in 2 cases.Conclusion Nontumorous intrahepatic vascular shunts could be divided into microscopic shunts that ultrasound could not directly display and shunts ultrasound could display.The former was characterized by early enhancement of the draining vein(portal vein or hepatic vein)on CEUS,some with early enhancement and no washout of local liver parenchyma.The latter was characterized by continuous enhancement of drainage vein and shunts,with or without transient low enhancement of local liver parenchyma.
