A nurse is caring for a client with cirrhosis who is scheduled to undergo a Transjugular Intrahepatic Portosystemic Shunt (TIPS) procedure. What is the primary purpose of this procedure in clients with cirrhosis?

Cirrhosis leads to progressive scarring of the liver, which increases resistance to portal blood flow and results in portal hypertension. This condition can cause complications such as variceal bleeding, ascites, and splenomegaly. A Transjugular Intrahepatic Portosystemic Shunt (TIPS) is an interventional radiology procedure used to reduce portal pressure by creating a controlled connection between the portal and hepatic venous systems. This allows blood to bypass the scarred liver tissue and flow more freely, reducing complications of portal hypertension. Rationale: A. Decreasing portal hypertension by providing an alternate pathway for blood flow is the primary purpose of a TIPS procedure. The shunt diverts blood from the high-pressure portal vein directly into the systemic circulation through the hepatic vein. This reduces complications such as esophageal variceal bleeding and refractory ascites, which are common in advanced cirrhosis. B. Delivering chemotherapy directly to liver lesions is not the purpose of a TIPS procedure. That approach is associated with other interventional techniques such as hepatic artery infusion or chemoembolization. TIPS focuses on vascular decompression rather than cancer treatment or localized drug delivery. C. Performing a liver biopsy for assessing liver fibrosis is not related to TIPS. Liver biopsy involves obtaining a tissue sample to evaluate the extent of liver damage, usually done via needle aspiration or transjugular sampling. Although the transjugular route may be used for biopsy, it is a separate diagnostic procedure, not the goal of TIPS. D. Facilitating liver transplant by improving liver function is not the primary role of TIPS. While it may temporarily stabilize complications of portal hypertension and improve quality of life, it does not reverse liver damage or restore hepatic function. Liver transplantation remains the definitive treatment for end-stage cirrhosis.
