摘要
目的 探讨彩超引导微波热凝固治疗原发性肝癌的临床价值。方法 应用彩超引导对 35例 5 6个结节组织学诊断证实为肝癌的病人行微波热凝固治疗 ,观察肿瘤血供变化、声像图特征等与临床疗效的关系。结果 治疗前彩色多普勒超声检查 5 6个结节内有血流信号者 5 1个 ,治疗后血流信号完全消失或减少率为96 1% ,其中 ,完全消失率为 70 6 % ;治疗后AFP下降率为 87 5 % ,转阴率为 70 8% ;治疗后 1～ 3个月 5 6个结节中 ,4 6个结节 (82 1% )体积缩小 2 5 %以上。结论 彩超引导下经皮微波热凝固技术是治疗肝癌的有效方法。彩超为观察手术前后肝癌血供变化、声像图变化提供主要依据 ,且简单易行 ,费用低廉 ,是指导治疗和评价疗效的有效方法。
Objective To study the effect of percutaneous microwave coagulation therapy on hepatic carcinoma under guidance of color dopler flow imaging (CDFI). Methods 35 patients with 56 nodules of hepatocellular carcinoma were treated with percutaneous microwave coagulation therapy under the guidance of CDFI. It was observed that the changes of the blood supply before and after the treatment and the relationship between sonographic characteristics and clinical effects were included. Results The disappering and reducing rate of blood stream signals around and within the tumor was 96.1% after the treatment. Among them the complete disappearing rate was 70.6% and 70.8% of the cases with AFP turned from positive to negative. Ultrasonographic examinition 1～3 months after therapy showed that in 46 cases (82.1%) the size decreased more than 25%. Conclusion Percutaneous microwave coagulation therapy on hepatocellular carcinoma under the guidance of CDFI might be a new effective way.
