Summary

The primary purpose of this project is to determine if acute monitoring of shunt patency via ultrasound elastography measurements of splenic stiffness before and after TIPS placement results in reduced morbidity and mortality from shunt failure.

Detailed description

Portal hypertension is a condition that is caused by various disorders of the liver, including cirrhosis, hepatitis, portal vein thrombosis, or Budd-Chiari Disease. Portal hypertension can lead to the accumulation of fluid in the abdomen, called ascites, or put patients at risk for bleeding of the esophagus, stomach, and bowel. In certain patients, portal hypertension is treated by placement of a Transjugular Intrahepatic Portosystemic Shunt (TIPS). Elastography is a newer exam which measures the consistency, or softness/stiffness, of various organs in the body. It is performed with ultrasound by sliding a transducer across the abdomen. Elastography is most commonly used to evaluate the liver, as disorders that cause damage to the liver result in stiffer liver tissue. The spleen has also been shown to get stiffer in the setting of portal hypertension.

TypeNameDescription
PROCEDURETransjugular Intrahepatic Portosystemic ShuntThe TIPS procedures creates an artificial shunt from the portal vein to the hepatic vein. TIPS allows blood from the congested portal circulation to bypass the fibrotic liver and directly enter the systemic circulation.
