Purpose

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.

TIPS 		Participants will have measurements taken of spleen stiffness before and after TIPS. Participation will last about 12 months, with visits at 1-2 weeks post-TIPS, 3 months, 6 months, and 12 months.
  • Procedure: Transjugular Intrahepatic Portosystemic Shunt
    The 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.

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.

Notice

Study information shown on this site is derived from ClinicalTrials.gov (a public registry operated by the National Institutes of Health). The listing of studies provided is not certain to be all studies for which you might be eligible. Furthermore, study eligibility requirements can be difficult to understand and may change over time, so it is wise to speak with your medical care provider and individual research study teams when making decisions related to participation.
