摘要
目的：探讨不同穿刺方案形成的肝组织微波凝固区的大小、形态，为临床治疗，特别是大肝癌的治疗，提供实践基础。方法：利用离体新鲜牛肝，比较ＵＭＣ－Ｉ型微波仪单针、两针及多针组合所形成凝固区的大小、形态。结果：单针穿刺可形成３．０ｃｍ×４．０ｃｍ头宽尾窄的滴水状凝固区。两针组合，距离在２．５～３．０ｃｍ之间造成的完全凝固区最大。不同穿刺方案，可形成８ｃｍ以下不同直径的球形凝固区。
Objective: To determine puncture strategies for different size of microwave coagulation, providing information for clinical application of microwave coagulation for liver neoplasm, especially for large tumor. Methods:Observing the size of coagulation of cattle liver in vitro with single, double and multiple punctures strategies by UMC-I microwave coagulator.[WT8.5HZ]Results:①The size of coagulation for single puncture was 3.0 cm ×4.0 cm.②The distance of two puncture ranging from 2.5 to 3.0 cm created maximum coagulation diameter.③Different puncture strategies produced different sizes of complete coagulation(<8 cm in diameter).Conclusions:With suitable puncture strategies, large sizes of complete coagulation can be achieved.
