Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Public title
A Prospective Study to Investigate the Correlation between Wedged Hepatic Venous Pressure and Direct Portal Venous Pressure during formation or revision of Transjugular Intrahepatic Portosystemic Shunt
Scientific title
In patients undergoing formation or revision of a transjugular intrahepatic portosystemic shunt, does the wedged hepatic vein pressure acurately reflect the direct portal venous pressure?

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Measurement of wedged hepatic vein pressure. This involves wedging a balloon catheter in a hepatic vein branch and measuring the pressure. This is done immediately prior to the formation of the Transjugular Intrahepatic Portosystemic Shunt. When the portal vein is accessed by the shunt, the direct portal vein pressure is measured. This will be compared to the initial hepatic vein wedge pressure measurements for the purpose of teh study. These measurements will add approximately 5 minutes to the scheduled procedure (which takes approximately 40 minutes in total)

Outcomes
Primary outcome [1] 240475 0
Degree of correlation between wedged hepatic vein pressure and direct portal pressure. This will be assessed by measuring hepatic vein wedge pressures at multiple sites then measuring the direct portal venous pressure once the transjugular intrahepatic portosystemic shunt has been formed. The average of the wedged hepatic vein pressures will be compared to the direct portal vein pressure.
