Volumetric Flow in TIPS

Other group

Description:

Subjects who have TIPS (transjugular intrahepatic porto-systemic shunts) have measurements taken to determine if someone has increased blood pressure in the portal vein of the liver (portal hypertension). Subjects who have a TIPS receive clinical ultrasounds every 3 months to determine if the TIPS is working properly.

Treatment:

Procedure: Volumetric Flow in TIPS
