Abstract

In clinical practice, a large number of patients might not undergo transcatheter hepatic angiography as a routine examination, which resulted in missed diagnosis of arteriovenous fistula (AVF) associated with hepatocellular carcinoma (HCC) and loss of embolism opportunity. The study was designed to investigate multidetector spiral CT (MDSCT) findings of AVF associated with HCC, so as to improve its diagnosis and differential diagnosis. Thin-slice and dynamic enhancement MDSCT findings of AVF proved by digital subtraction angiography of 56 patients with HCC were analyzed. MDSCT demonstrated earlier enhancement of main portal trunks and/or the first order branches than superior mesenteric veins or spleen veins (n=31), 1 patient had early enhancement and strong enhancement of left hepatic vein with thromboses in it and upper part of inferior vena cava, 1 patient had transient patchy enhancement peripheral to HCC focus in late hepatic arterial phase and became isoattenuation at portal vein phase among them; stronger opacification of main portal trunks and/or the first order branches than superior mesenteric veins or spleen veins (n=18); earlier enhancement of the second order branches and smaller of portal veins than main portal tr...Continue Reading
