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

Figure 1

Schematic of the balloon anchor technique. (a) When selective cannulation of the feeding artery of the tumor was not possible using conventional methods, a microballoon catheter was inserted into a nontarget branch. (b) The balloon was inflated and fixed in the vessel. (c) The parent catheter was advanced along the fixed microballoon catheter. (d) The microballoon catheter was advanced into the feeding artery and selective balloon-occluded transarterial chemoembolization was performed.
