Comparison of the efficacy of PVA particles and Embosphere microspheres in the treatment of hypersplenism / 实用放射学杂志

ABSTRACT

Objective To compare and analyze the efficacy of PVA particles and Embosphere microspheres for partial splenic embolization (PSE)in the treatment of hypersplenism secondary to liver cirrhosis.Methods Sixty patients underwent PSE for treatment of hypersplenism secondary to liver cirrhosis were analyzed retrospectively.According to different PSE embolization materials,they were divided into two groups30 patients with PVA particles embolization (group A),and other 30 patients with Embosphere microspheres embolization (group B).The changes of white blood cells (WBC),platelets (PLT),spleen thickness,portal vein diameter and postoperative pain and fever were compared on the 3rd day,the 1st week,the 3rd week,the 1st month,the 3rd month,and the 6th month after PSE and compared between the two groups.Results The WBC and PLT of the 2 groups after PSE were significantly higher than those before PSE (all P＜0.05 ).The spleen shrank after 2 months,and there was no significant difference in spleen thickness and portal vein diameter between the two groups at the same time (all P＞0.05).The postoperative pain in group A was significantly less than that in group B (P＜0.05).Conclusion Both PVA particles and Embosphere microspheres have good curative effect in the treatment of hypersplenism secondary to liver cirrhosis. The price of PVA particles is lower than that of Embosphere microspheres,and the postoperative pain degree is lighter than that of Embosphere microsphere,which suggests PVA particles with more advantages in clinical application.
