Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Measures portal, hepatic venous, and systemic venous pressures and pressure gradients during TIPS creation, TIPS revision, and other portal-hypertension assessments using a fluid-filled catheter and transducer setup.
What most clearly distinguishes it from similar devices?
Key distinctions
This is a hemodynamic measurement setup rather than a unique catheter shape; accurate values depend on correct leveling, zeroing, and an intact fluid-filled pressure circuit.
