The present study aimed to analyze the feasibility, safety and effectiveness of ultrasound-guided percutaneous microwave ablation of splenic neoplasm. A total of 62 patients with splenic neoplasm admitted to Second People's Hospital of Liaocheng between January 2009 and December 2012 were selected, and randomly divided into the observation group (n=31) and control group (n=31). The control group was treated with open ablation, while the observation group was treated with ultrasound-guided percutaneous microwave ablation. The splenic hemodynamics and ablation effects of patients after treatment were detected via color Doppler ultrasound. The changes in peripheral blood cell count before treatment, and at 3, 7 and 14 days after treatment were monitored. The side effects and complications were compared between the two groups. Patients were followed up for 5 years to observe the survival rates of the two groups. At 1 week after treatment, the peak velocity of splenic artery in observation group was significantly lower than that in control group, and the diameter, velocity and flow of splenic vein were significantly lower than those in control group (P&lt;0.05). After treatment, the white blood cell and platelet counts in both groups were significantly increased compared with those before treatment, and the counts in observation group were obviously higher than those in control group (P&lt;0.05). There were no significant changes in the red blood cell counts in both groups before and after treatment (P&gt;0.05). The ablation volume, ablation ratio and 1-week shrink ratio in both groups had no significant differences (P&gt;0.05). The incidence rates of side effects and complications in observation group were significantly lower than those in control group (P&lt;0.05). The 5-year survival rates of both groups were &gt;50%, and the survival time and survival rate were not significantly different (P&lt;0.05). The curative effects of open ablation and ultrasound-guided percutaneous microwave ablation in the treatment of splenic neoplasm were significant, and the 5-year survival rate of patients was higher; compared with open ablation. The ultrasound-guided percutaneous microwave ablation is characterized by the small trauma, lower incidence rates of adverse reactions and complications and better safety, which can increase the peripheral blood cell count, and improve the splenic blood flow and coagulation function, playing a role in the regulation of the patient's body status.
