Hepatic aneurysms, pseudoaneurysms and fistulas (arterial biliary and arterial portal) causing blecding or portal hypertension, and arteriovenous malformations causing high output cardiac failure in adults can be successfully managed by embolization techniques. Results of embolization in infantile hemangioendotheliomas are less uniform and tumors with massive arteriovenous shunting are difficult to manage. Transjugular intrahepatic portal systemic shunts using expendable stents have been successfully created in patients and have effectively controlled portal hypertension and variceal bleeding.
