Summary

To determine if ultrasound measurements can accurately measure the blood pressure of flow across a stent that has been placed in a portal vein to reduce portal vein pressure known as Transjugular Intrahepatic Porto-Systemic shunts or TIPS.

Detailed description

To determine if 3D ultrasound measurements can accurately measure the pressure of blood flow across a stent that has been placed in a portal vein. This has been done in order to reduce portal vein pressure. These shunts are known as Transjugular Intrahepatic Porto-Systemic shunts or TIPS.

Conditions

• Portal Hypertension
• Liver Disease

Interventions

Type	Name	Description
PROCEDURE	Volumetric Flow in TIPS	Subjects who have a TIPS (transjugular intrahepatic portal-systemic shunt) for portal hypertension will undergo a clinical 3D ultrasound to determine if the TIPS is working properly. Additional ultrasounds will be obtained during the subject's clinically ordered ultrasound(s). These measurements will be taken by using a second ultrasound probe (plastic hand held device that is rubbed along the subject's abdomen). 15 minutes will be added to your clinically ordered exams that are completed 4 times a year.
