在相同临床特征和外围性栓塞技术条件下，分别用白芨粉和明胶海绵颗粒中央性栓塞肝动脉治疗肝癌５６例和５０例。结果表明：白芨粉呈永久性“铸型”状栓塞，栓塞后侧支循环形成少、形成晚，该组病人的１、２、３年生存率分别为８１．９％、４４．９％、３３．６％，平均生存期为１９．８月。白芨组的疗效优于明胶组，且重复治疗间隔长、次数少。
Under the same clinical characteristics and peripheral embolization techniques, hepatic artery was centrally embolized with alum powder and gelatin sponge particles respectively to treat 56 cases of liver cancer and 50 cases of hepatocellular carcinoma. The results showed that the white peony root powder had a permanent “cast mold” embolism. After the embolization, the collateral circulation formed less and formed late. The 1-, 2-, and 3-year survival rates of this group of patients were 81.9% and 44.9%, respectively. 33.6%, with an average lifetime of 19.8 months. The efficacy of the white peony group was better than that of the gelatin group, and repeated treatment was performed at a longer interval and less frequently.
