ARTERIOPORTAL FISTULAS IN THE EXTRAHEPATI C PART OF THE COMMON HEPATIC-ARTERY - DIAGNOSIS AND VASCULAR RADIOLOGIC INTERVENTION

Two cases of arterioportal fistulas and new possibilities in diagnosis and treatment are reported: A 62-year-old women was admitted to our h ospital with abdominal pain. Color flow duplex sonography showed an ar terioportal fistula between the proper hepatic artery and the ectatic portal vein that was confirmed by angiography, permitting percutaneous embolization as a definitive treatment. The pain disappeared immediat ely. A 36-year-old man underwent surgery due to a penetrating gastric ulcer. He was referred to us with an abdominal murmur. Color flow dupl ex sonography proved by spiral CT with 3D reconstruction and maximum i ntensity projection (angio-CT) revealed an arteriovenous fistula betwe en the gastroduodenal artery and a mesenteric branch. Angiography conf irmed the diagnosis and permitted definitive therapeutic embolization.
