Fig. 1. The first case of super-selective lipiodol balloon-occluded transarterial chemoembolization performed in 1991 using a coronary angioplasty balloon catheter. A coronary angioplasty catheter was passed through a 7 F guiding catheter and placed in subsegment 8 artery. Lipiodol emulsion was infused under balloon-occlusion and a spot radiography was obtained before embolization of gelatin fragments. Densely accumulated lipiodol in hepatocellular carcinoma nodule and adhesion of a lipiodol droplet at the catheter tip were seen (arrow).
