Comparing a Direct Versus an Indirect Approach to Measuring the Portalsytemic Pressure Gradients

January 12, 2024 updated by: Cook Research Incorporated

Endoscopic Ultrasound-Guided Portosystemic Pressure Gradient Measurements vs. Transjugular Balloon Occlusion Measurement: A Multicenter EU Study

The objective of this study is to evaluate the correlation of the calculated portosystemic pressure gradient (PPG) obtained by direct portal and hepatic pressure measurements with the EchoTip® Insight™ and indirect portal vein pressure measurements using the interventional radiology based hepatic venous pressure gradient (HVPG) procedure.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with cirrhosis who have been referred for a HVPG procedure.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Direct and indirect PPG measurements
Measuring the portalsystemic pressure gradient in patients directly using the EchoTip® Insight™ and indirectly through the HVPG procedure.
Device: EchoTip® Insight™
Patients will undergo procedure where HVPG is obtained under mild sedation, next the patients will undergo anesthesia and mechanical intubation where HVPG measurements will be obtained simultaneously with the EchoTip Insight measurement. For patients receiving a transjugular intrahepatic portosystemic shunt (TIPS), direct portal vein pressure measurements will be obtained by the EchoTip® Insight™ and compared to the transjugular direct portal vein measurement obtained during the interventional radiology (IR) procedure.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The correlation between the direct and indirect procedures to measure PPG.
Time Frame: The period from the start of the procedure until all measurements are completed is anticipated to be approximately two hours
Under general anesthesia, to quantify the correlation between the calculated PPG from the EchoTip® Insight™ direct measurements (difference between direct portal vein pressure and direct hepatic vein pressure) and indirect HVPG measurement (difference between transjugular free hepatic venous pressure (FHVP) and wedge hepatic venous pressure (WHVP) obtained during an IR procedure.
The period from the start of the procedure until all measurements are completed is anticipated to be approximately two hours

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
