目的 对 CT引导下经皮肺穿刺锚状电极高温射频治疗肺转移瘤的临床效果和安全性进行研究 .方法 对 2 4例患者 16 1个不同病理类型的肺转移瘤进行锚状电极高温射频治疗 ,观察无创血压、脉搏和周围血氧饱和度的变化 ;治疗前后肺功能的变化 ;治疗后 CT扫描肿瘤组织中低密度影和肿瘤体积的变化 .结果 2 4例患者治疗中血压、脉搏和周围血氧饱和度无明显改变 ;治疗后肺功能无明显改变 ;治疗后1wk内 CT扫描显示肿瘤体积均增大 ,治疗后 3m o肿瘤体积通过 CT扫描显示在 16 1个肿瘤中完全衰退 (CR) 2 3个(10 0 %衰退 ) ,部分衰退 (PRa) 98个 (80 %～ 10 0 %衰退 ) ,部分衰退 (PRb) 37个 (5 0 %～ 80 %衰退 ) ,无衰退 (NR) 3个 (衰退小于 5 0 % ) ;治疗后 3 mo CT扫描显示肿瘤内低密度影 型 3个 , 型 5 9个 , 型 99个 .结论 锚状电极高温射频治疗肺转移瘤效果良好并且创伤小 ,有良好的发展前景 .
Objective To study the clinical effects and safety of high-temperature radiofrequency treatment of lung metastases by CT guided percutaneous pulmonary puncture anchored electrodes.Methods 16 2 pulmonary metastases of different pathological types were treated with high-frequency radiofrequency catheter anchors , The changes of non-invasive blood pressure, pulse and peripheral oxygen saturation were observed.The changes of lung function before and after treatment, the changes of low-density CT and tumor volume in CT scan after treatment.Results The blood pressure, pulse and circumference No significant changes in oxygen saturation; no significant changes in lung function after treatment; CT scan within 1wk after treatment showed an increase in tumor volume, 3m o tumor volume after treatment by CT scan showed a complete decline (CR) in 16 1 tumors 23 (10% decline), partial recession (PRa) 98 (80% ~ 100% decline), partial recession (PRb) 37 (50% ~ 80% decline), no recession (Less than 50% decline); CT scan at 3 months after treatment showed that there were 3 low density type, 59 type, 99 type in the tumor.Conclusion The high temperature radiofrequency of the anchor electrode can effectively treat pulmonary metastases with less trauma, Have a good hair Prospects.
