Intraparenchymal anesthesia infiltration during transjugular intrahepatic portosystemic shunting.

Abstract

The authors describe a technique for administration of anesthetic to the area of the transparenchymal tract during transjugular percutaneous transhepatic portosystemic shunting. Seven of the eight patients in whom the technique was used did not experience pain during balloon dilation of the tract, and one patient experienced only minimal pain. The technique allows good pain control in patients with severe liver failure and resultant inability of the liver to metabolize pharmaceuticals.
