Abstract:ObjectiveTo investigate the influence of radiofrequency ablation(RFA) combined with 5FuMAMS injection on the ablation volume.MethodsThe subjects used in this experiment were fresh ex vivo bovine livers.Three groups were set up:Group Ⅰ,RFA alone;group Ⅱ,RFA combined with 5fluorouracil;group Ⅲ, RFA combined with 5fluorouracil magnetic albumin microspheres.The size and shape of coagulation necrosis zones were observed and measured.Single factor analysis of variance was used to analyze the affecting factors for the size of ablation lesions.Macroscopic and microscopic morphological characteristics of lesions were observed.ResultsIn gross examination,all ablation lesions were gray elliptical in cross section and there were classical coagulation necrosis.The central organization was drying,and the treatment area and surrounding liver tissue boundaries were clear.The mean biggest longitudinal diameter and transverse diameter of necrosis volume of group I,group II and group III were (4.45±0.23)cm,(4.93±0.53)cm,(5.68±0.59)cm(F=10.23,P<0.05)and (2.83±0.25)cm, (3.08±0.22)cm, (4.10±0.14)cm respectively(F=61.23,P<0.05). The necrosis volumes of group Ⅲ(RFA combined with 5FuMAMS) were bigger than those of control group(P<0.05).The mean durations were (472.00±20.49)s,(632.50±21.05)s and (836.50±19.10)s (F=489.28,P<0.05).The average temperature at 3cm distance from the center of the puncture point were (41.83±2.04)℃,(47.33±3.83)℃ and (55.67±2.16)℃ (F=37.20,P<0.05).All the differences were statistically significant.ConclusionsCompared with other two groups,RFA combined with 5fluorouracil can produce larger ablation zones.The lesions typically showed coagulation necrosis at microscopicaI examination.
