Intrahepatic arterioportal fistula and its treatment with detachable balloon and transcatheter embolization with coils and microspheres.

ABSTRACT

BACKGROUND: Although intrahepatic arterioportal fistula (APF) due to acquired or congenital causes are infrequent, they are listed among the causes of portal hypertension. PURPOSE: The aim of this study was to present the results of intrahepatic APF treatment with embolotherapy in six cases. MATERIAL AND METHODS: Transarterial detachable balloon and coil embolization was used on six consecutive cases with traumatic intrahepatic APF from 1989 to 2003. Six-month follow-up angiography was obtained in every case. RESULTS: Successful disconnection of hepatic arterial and portal system was achieved in five cases. At least symptomatic improvement was achieved in one. CONCLUSION: Transcatheter embolization may be the first line of treatment for intrahepatic APF.
