CT引导下经皮穿刺氩氦刀靶向冷冻治疗肾癌

目的初步建立氩氦超导手术系统(简称氩氦刀)靶向冷冻治疗肾癌的技术和探讨其原理、安全性及近期疗效。方法7例肾癌患者采用氩氦刀,在CT引导下经皮穿刺对肿瘤病灶行冷冻治疗。结果7例患者冷冻治疗后未出现出血、皮肤冻伤、感染或穿刺道种植转移等严重并发症。7例在冷冻治疗后1个月,CT显示病灶区内出现低密度坏死区,5例肿瘤大小无改变,2例瘤体有不同程度缩小。结论CT引导经皮穿刺氩氦刀冷冻治疗肾癌是一种安全、有效、微创治疗,特别是对于不能行手术切除的肾癌病例。

Percutaneous targeted argon-helium cryoablation for renal carcinoma under CT guidance

Objective To establish initially the technique and evaluate the principle, safety and short term efficacy of argon-helium superconductor operation system (or Ar-He knife) targeted cryotherapy for renal carcinoma. Methods Seven patients with renal carcinoma were treated with CT-guided percutaneous Ar-He knife targeted cryotherapy. Results After cryotherapy, no serious complications, such as bleeding, skin cold injury, infection, implantation metastasis inside the puncture path occurred, and one month later, CT scans showed low-density local necrosis in all tumors of the 7 cases , but the tumor reduction in size was found only in 2 cases. Conclusion CT guiding percutaneous Ar-He knife targeted cryoablation for renal carcinoma is a safe , effective and minimally invasive therapeutic method, particularly for inoperable cases.
