Abstract
Six patients with advanced cirrhosis and portal hypertension had life-threatening upper gastrointestinal hemorrhage from esophageal varices. The varices were obliterated angiographically, using the transjugular approach, after which an intrahepatic portosystemic shunt was created in each case by inflating the balloon of a Gruntzig dilatation catheter in the needle tract between the portal and hepatic veins. All of the patients were expected to succumb quickly to their severe liver disease and massive variceal bleeding, but three of the six survived the initial hemorrhage, and two of these were discharged from hospital. There was an initial reduction of portal venous pressure of 10-15 mm Hg in all patients. All six shunts were patent angiographically 12 hr after the procedure. Two patients had venograms 5 days later and both shunts were patent. All six patients died within 6 months, but in three of the four postmortem examinations the shunts were easily identified and shown to be patent, the last of these 6 weeks after the procedure. These findings suggest that the technique could be of therapeutic value in the management of patients with portal hypertension.
