目的 探讨集束电极 (多弹头 )射频 (RF)对正常肝脏组织及全身的影响。方法 将 2 5头 1 5kg的猪随机分为A、B、C、D、E 5组 ,分别对其RF作用前及作用后 1、3、5、7、1 4d的肝功能及病理学改变进行观察。结果 1周内肝功能出现一过性改变 ,1周后恢复正常 ;作用后第 3～ 7天凝固坏死范围最大 ,7～ 1 4d凝固坏死区外的肝脏炎性改变恢复正常。结论 集束电极射频对肝毁损确切 ,肝功能及凝固区外的肝组织也将出现暂时性改变 ,1周后恢复正常
Objective To investigate the effect of cluster electrodes (multiple warheads) radio frequency (RF) on normal liver tissue and whole body. Methods Twenty-five pigs of 15kg were randomly divided into A, B, C, D and E 5 groups, and their liver function and pathological changes were observed before and after 1, 3, 5, 7, Observe. Results The liver function changed transiently within 1 week and returned to normal after 1 week. The range of coagulation and necrosis was the highest on the 3rd to 7th days after operation, and the inflammatory changes outside the coagulation necrosis area of 7 to 14 days returned to normal. Conclusions The radio-frequency of cluster electrode has definite damage to the liver, and liver function and hepatic tissue outside the coagulation area will also be temporarily changed, returning to normal after 1 week
