Dynamic Monitor of Portacaval Pressure Gradient

"Covered stents will be used, that will be dilated to 8 mm. The aim will be to reduce the portacaval pressure gradient (PPG) below to 25-75% of baseline. Not paralleled TIPS or over-dilatation are allowed.~Embolisation, either with coils or bucrylate, can be performed, if it is felt necessary, especially in patients where portography shows the filling of big portosystemic collaterals feeding the varices.~After TIPS, anticoagulation will not be used as a rule, but is allowed if the attending physician thinks that it is warranted.~Measurement of portacaval pressure gradient will be done immediate after TIPS, then repeated 1-3 days and at 1 month after the procedure.~A TIPS revision will be performed once shunt dysfunction is suspected."
