ABSTRACT
Objective To compare the effect of single implanted microwave ablation in continuous and interval irradiating in ex vivo pig muscular tissues, and to provide the experimental data for microwave ablation therapy of uterine fibroid clinically. Methods The pig muscular tissues ablations were performed with 2450 MHz microwave at same output power and action time. The irradiating modes were set as continuous wave and interval wave (emitting per 100 seconds intermitting 10 seconds and 20 seconds). The shape, size, thermal field temperature and the pathologic appearance of the ablation zone were evaluated. Results With the same output power and the same action time,the difference observed in the ablated shape, scope, ahead distance and thermal field temperature had no statistical significance, and the pathologic appearances of the ablated zone were same among the different action modes. Conclusions The difference between continuous and interval microwave ablation effects had no statistical significance in ex vivo pig muscular tissues with single implanted microwave. Both of these two modes may apply for uterine fibroid microwave ablation,and may result in same therapeutic efficacy.
