Abstract
Spontaneous intrahepatic portosystemic venous shunt (SIPSVS) is relatively rare and not well recognized. Herein, we report 75-year-old female of an aneurysmal portosystemic venous shunt detected by colour Doppler ultrasound in check-up examination. A direct vascular communication between left portal vein and middle hepatic vein was confirmed by CT-angiography. The cause of intrahepatic portosystemic venous shunt is disputed. This abnormality, mainly described in cirrhotic liver and rarely in healthy liver, is usually revealed by hepatic encephalopathy or glycoregulation disorders. However, with improvements in imaging the number of reports of SIPSVS identified incidentally in patients without definite symptoms increasing.
Highlights
Macroscopic intrahepatic portosystemic venous shunts is defined as communications between the portal and the systemic venous circulation, measuring more than 1 mm in diameter, and at least partially located inside the liver
Portosystemic shunts are expected to be associated with portal hypertension, trauma, surgical intervention or liver biopsy, but incidentally seen otherwise normal individuals
These spontaneous intrahepatic portosytemic shunts (SIPSVS), except for dilated paraumbilical veins caused by portal hypertension, have generally been considered to be rare even though modern imaging modalities have successfully demonstrated these abnormalities [5,10,12,14,18,19,21, 23,27,28]
