RESUMEN
OBJECTIVE: The purpose of this study was to investigate a new method-the portal vein enhancement curve-for quantifying portal vein blood flow immediately at transjugular intrahepatic portosystemic shunt (TIPS) creation using digital subtraction angiography images and its potential usefulness as a predictor of TIPS revision. CONCLUSION: The portal vein flow time constant, Qτ, was significantly different (p = 0.002) between patients grouped by 12-month revision (TIPS angioplasty, TIPS reduction, no revision); Qτ was higher in patients who required TIPS reduction.
