Hepatic Arteriovenous Fistula in Four Dogs: Usefulness of Dual-phase Computed Tomographic Angiography

Abstract

Four small breed dogs were presented with various clinical signs, including seizures. Dual-phase computed tomography (CT) angiography of the abdominal region revealed early enhancement of the venous system during the arterial phase, and this finding is considered classic indication of hepatic arteriovenous fistula in CT angiography. This case report presents the clinical and diagnostic findings of hepatic arteriovenous fistula in four small breed dogs.
