A 75-year-old male who underwent transcatheter arterial chemoembolisation (TACE) (cisplatinum 150 mg and gelatin sponge) for hepatocellular carcinoma (T4, vp3), using 5.2 ml kg-1 diatrizoate. His serum creatinine level before the procedure was 0.9 mg dl-1 (79 µmol l-1) and he did not show nephropathy. (b) RCR grade 2. A 70-year-old female who underwent TACE (cisplatinum 50 mg, adriamycin 20 mg, lipiodol 6 ml and gelatin sponge) for hepatocellular carcinoma (T4), using 5.1 ml kg-1 diatrizoate. She showed severe RCR with nephropathy. Her serum creatinine level raised to 1.9 mg ml-1 (167 µmol l-1) 1 day following TACE (from 1.3 mg ml-1 (114 µmol l-1) before the procedure) and recovered to normal value 3 weeks later without haemodialysis.
