Objectives: After studying the article entitled “Transjugular Intrahepatic Portosystemic Shunt: A Literature Review,” you will be able to:
List three indications for performing a TIPS procedure
Recognize 2D and color Doppler sonographic findings associated with an abnormal transjugular intrahepatic portosystemic shunt
List the most common postprocedure complications associated with TIPS
The goal of an intrahepatic portosystemic shunt is to Increase the blood flow through the liver Reduce portal venous pressure and portal hypertension Shunt blood from the hepatic venous system to the portal venous system Administer contrast to the biliary system
Which vessel is responsible for supplying two-thirds of the blood flow volume into the liver? Hepatic artery Hepatic vein Main portal vein Esophageal vein
What are the two most common indications for TIPS? Refractory ascites and variceal bleeding Budd-Chiari syndrome and hepatorenal syndrome Cirrhosis and hepatic hydrothorax Portal hypertension and biliary obstruction
Ascites is triggered by vasodilatation of what vessel? Splanchnic artery Splanchnic vein Hepatic artery Hepatic vein
Which of the following is a sonographic finding that demonstrates abnormal TIPS function? Anechoic lumen by 2D imaging Color flow filling the stent lumen Doppler velocity >250 cm/s within the stent Increased hepatic artery flow
Which statement is true concerning a TIPS procedure? TIPS procedures are only performed in the operating room under general anesthesia The right jugular vein is preferred over the left jugular vein Preprocedural imaging is necessary to verify portal vein patency The left hepatic vein is mostly commonly selected to create the shunt
What postprocedure complication has been reduced by the introduction of PTFE-covered stents? Stent occlusion Stent stenosis Stent retraction Hepatic encephalopathy
