title: A new technique for transhepatic liver tract dilatation. An aid in transhepatic portography.
abstract: Transhepatic portography is frequently difficult or unsuccessful in cirrhotic patients because of catheter friction by the fibrotic liver and the presence of ascites. The authors describe a technique of liver tract dilatation which circumvents these difficulties.
