title: Combined use of an occlusion balloon catheter and a microcatheter for embolization of the unselectable right inferior phrenic artery supplying hepatocellular carcinoma.
abstract: We report the combined use of an occlusion balloon catheter and a microcatheter for transcatheter arterial embolization (TAE) of hepatocellular carcinoma (HCC) fed by the unselectable right inferior phrenic artery (IPA). In one case, HCC was fed by the reconstructed right IPA via a small branch arising from the proximate portion of the celiac artery. In another, the tumor was fed by the right IPA that had been previously embolized with coils. TAE was successfully performed through a microcatheter placed in the celiac artery immediately proximal to the occluding balloon catheter of the celiac trunk and coil embolization of the left gastric artery.
