RESUMO
Occasionally, routine computed tomography will fail to demonstrate substantial deposits of metastatic neoplasm in the liver. Repeating the CT scan with selective hepatic arterial infusion of contrast media may demonstrate these lesions. Nuclear magnetic resonance imaging may also provide the same information, avoiding the necessity of an invasive procedure.

A 49-year-old woman with cirrhosis and portal hypertension was evaluated for a portal-systemic shunt procedure following recurrent variceal hemorrhage. The preoperative visceral angiogram demonstrated a hepatic arterial to portal venous fistula, presumably a complication of a previous liver biopsy. The fistula was successfully closed using isobutyl-2-cyanoacrylate (Bucrylate) delivered through a flow-directed, calibrated-leak balloon microcatheter.

The oblique bending projection, when incorporated into routine radiographs during oral cholecystography, was found to be at least as effective as fluoroscopic spot radiographs in obtaining information about the gallbladder.
