  目的:探讨氩氦刀冷冻消融治疗恶性肾肿瘤的临床疗效.方法:应用氩氦刀冷冻消融治疗恶性肾肿瘤患者23例.CT引导下经皮肾穿刺9例,后腹腔镜下9例,开放手术5例.结果:术后第1、6个月复查CT或MRI,肾肿瘤冷冻区域呈梗死、无信号增强、逐渐消散等演变过程.23例均未见出血、皮肤冻伤、感染、穿刺道种植转移等严重并发症.随访1.5~ 48个月,平均28.5个月.21例健康存活,未发现远处转移和复发;死亡2例.开放手术治疗者5例,其中左肾平滑肌肉瘤1例于术后1.5个月因肿瘤广泛转移死亡;CT引导下治疗患者,1例肿瘤直径为8cm者术后10个月因脑血管意外死亡.结论:氩氦刀冷冻治疗恶性肾肿瘤技术可靠、创伤小、安全性高,是治疗孤立肾肾肿瘤或无法手术肾肿瘤的一种有效的新手段,对于小的肾肿瘤采用后腹腔镜下氩氦刀冷冻消融治疗是一种值得尝试的新方法.

自从射频消融术治疗心律失常问世以来,由于其成功率和安全性高,迅速在世界各地广泛推广.随着技术的进步和临床操作水平的提高,目前射频消融术已成为临床治疗快速性心律失常的一线治疗方法.近年来冷冻消融术也作为一种新的消融能源,开始在国内外应用于临床心律失常的消融治疗,其疗效也得到了临床实践和实验证实.与射频消融相比,在房颤的消融术中,冷冻消融术是一种安全无痛的术式,肺静脉狭窄的风险很低,特别是靠近房室结的
