title: CT features of iatrogenic hepatic arterioportal fistulae.
abstract: Peripheral arterioportal fistulae are a relatively frequent complication of hepatic biopsies and transhepatic catheterizations. Three cases were revealed by dynamic computed tomography (CT) and confirmed by angiography. The morphologic and densitometric characteristics of these arteriovenous fistulae on CT in most cases indicate the causal mechanism and eliminate consideration of tumor.
