New Method of Parent Catheter Advancement in the Balloon Anchor Technique during Balloon-Occluded Transarterial Chemoembolization for Hepatic Tumors

Figure 2

((a) and (b)) A 1.8 Fr tip coaxial microballoon catheter was inserted into a branch in segment five (arrow) that was unrelated to the feeding arteries of the tumor in segment eight. (c) The microballoon was inflated in the vessel (arrow) and the parent catheter was advanced into the right hepatic artery (arrowheads). ((d), (e), and (f)) Selective transarterial chemoembolization using miriplatin was performed and dense lipiodol deposition in the tumor was visible in the postprocedure computed tomography images. (g) Including the vessel in which the microballoon was inflated (arrow), no vascular complications were confirmed in the postprocedure angiogram.
