Unusual hepatic‐portal‐systemic shunting demonstrated by Doppler sonography in children with congenital hepatic vein ostial occlusion

Abstract

Ostial occlusion of the HV is a rare cause of hepatic outflow obstruction in children. Doppler sonography is a valuable, noninvasive imaging technique for evaluation of the hepatic vasculature and the accompanying shunting pathways in such cases.

Color Doppler sonography of intrahepatic vascular shunts

“…17 In this case, the hepatic venous circulation is mainly through subcapsular hepatic and portal venous collaterals [18][19][20] (Figure 15). In patients with hereditary hemorrhagic telangiectasia, arteriovenous shunts are prevalent, but intrahepatic portosystemic venous shunts may open as well.…”
