Intrahepatic venous and portal venous aneurysms examined by color Doppler flow imaging

Abstract

Thirteen cases with liver cystic lesions, which were suspected to communicate with intrahepatic vessels on the basis of ordinary sonography, were examined by color Doppler flow imaging. By this method, blood flow within the cystic lesion was detected in 5 of these cases, and the communication to the intrahepatic vessel confirmed. Information about the hemodynamics of aneurysms was obtained. Two of these lesions were diagnosed as an aneurysmal porta-hepatic venous fistula, another 2 as a portal venous aneurysm, and the remaining 1 as a hepatic venous aneurysm.
