Abstract: Objective To compare the efficacy of partial splenic embolization (PSE)with 150－350 μm and 350－560 μm polyvinyl alcohol (PVA).Methods A total of 24 patients were analyzed retrospectively in this study.Among them,9 patients underwent PSE with PVA of 1 50－350 μm (group A)and 1 5 patients with PVA of 350－560 μm (group B).Hematological parameters including white blood cell and platelet counts before and 1 week after surgery were compared between the two groups,as well as postoperative complications. Results The white blood cell and platelet counts were both significantly increased after 1 week of surgery compared with that before surgery (both P＜0.05).Furthermore,group A had obvious advantage over group B in increasing platelets (P＝0.05).The incidences of postoperative complications were 100% (9/9)in group A and 87% (13/15)in group B,respectively,but the incidence and severity of complications between two groups were comparable.Conclusion PSE with PVA of 1 50－3 50 μm has advantage in postoperative platelet improvement over PVA of 350－560 μm.
