Objectives: After studying the article entitled “Congenital Intrahepatic Portosystemic Venous Shunt With an Associated Aneurysm: Sonographic Diagnosis,” you will be able to:
Understand the origin of congenital intrahepatic portosystemic venous shunts
Describe the sonographic image characteristics of congenital intrahepatic portosystemic venous shunts
List treatment options for patients with congenital intrahepatic portosystemic venous shunts
What is the major morphological characteristic of an intrahepatic portosystemic venous shunt? Abnormal intrahepatic communication between portal system and hepatic veins Latrogenic creation of a shunt between the portal system and hepatic veins during liver biopsy An abnormal anastomosis between the intrahepatic biliary system and the portal system An unusual joining of the intrahepatic hepatic artery to the hepatic veins
What information can color Doppler sonography provide about intrahepatic portosystemic venous shunts? Shunt identification, shunt type, and blood flow direction Shunt location, blood flow profile, and hematocrit Blood flow direction, shunt type, and hepatic enzyme levels Type of shunt, maximum and minimum blood flow velocities, and blood flow profile
According to one research study, approximately what percentage of asymptomatic patients with an intrahepatic portosystemic venous shunt do not need any treatment? 52% 42% 30% 22%
