Abstract: Objective To explore the efficacy of the gelatin sponge particle and embosphere microsphere embolization for the treatment of patients with hepatocellular carcinoma and tumor rupture. Methods 49 patients with rupture of hepatocellular carcinoma underwent transcatheter arterial embolization by gelatin sponge particle （n=23） or embosphere microsphere（n=26） embolization in recent 5 years,and instant hemostatic and rehaemorrhagia rates were compared. Results There was no difference between gelatin sponge particle and embosphere microsphere embolization on the effects of instant hemostatic（both were 100%）;Seven days after intervention,the rehaemorrhagia rate in gelatin sponge particles was 13.0%（3/23）,one patient was transferred to surgery,one patient was re-intervened and one patient dead because of haemorrhagic shock,respectively;The rehaemorrhagia rate in embosphere microspheres group was 3.8%（1/26,P<0.01）,and the patient received re-intervention and the bleeding was stopped successfully. Conclusion The instant hemostatic effect is the same between the gelatin sponge particle and embosphere microspheres embolization in patients with rupture of hepatocellular carcinoma,however,the embosphere group has much less chance to rebleeding within 7 days.
