目的 经皮微波肝穿刺对肝癌进行热凝损毁 ,观察其对肝癌的作用疗效。方法 5 2例患者在局麻或硬膜外麻醉下 ,使用 2 45 0MHz微波微型穿刺天线 ,在B超引导下直接经皮穿刺进入肝癌瘤体内 ,对其进行热凝固。结果 5 2例患者的 97个瘤体中 ,直径均 <3cm的肿块 6 1个 (6 2 .9% )能1次手术热凝损毁 ,其中 5 7个 (93.4% )经CT或MRI检查 ,并随访 6～ 12个月 ,提示瘤体热损毁后未见复发 ;3～ 5cm的肿块 36个 (37.1% ) ,分 2次手术 ,术后 6个月CT或MRI检查提示 ,2 7个热凝损毁(75 .0 % ) ,9个大部分热凝损毁 (2 5 .0 % )。经皮微波热凝治疗 (PMCT)的患者均未见明显的副作用和其他并发症。结论 PMCT治疗肝癌 ,尤其对直径 <3cm的瘤体疗效可靠 ,对 >3.5cm或 <5cm的瘤体仍具有大部分或完全热损毁的作用。
Objective Percutaneous microwave hepatic puncture of hepatic cancer heat coagulation damage, observe its effect on the efficacy of liver cancer. Methods 52 patients under local anesthesia or epidural anesthesia, the use of 2 45 0MHz microwave micro-piercing antenna, guided by B-guided direct percutaneous puncture into the liver cancer, the thermal coagulation. Results Sixty-one (62.9%) of the 92 tumors with a diameter of less than 3 cm in 5 of the 52 patients were able to undergo one-time surgical hypothermia, of which 57 (93.4%) were examined by CT or MRI. And followed up for 6 to 12 months, suggesting no recurrence after thermal rupture of the tumor; 36 (37.1%) of 3 ~ 5 cm were divided into 2 surgeries, and CT or MRI 6 months after operation showed that 27 Condensation damage (75.0%), 9 most of the thermal coagulation damage (25.0%). Percutaneous microwave coagulation therapy (PMCT) in patients with no significant side effects and other complications. Conclusion PMCT treatment of liver cancer, especially for the diameter of <3cm tumor reliable,> 3.5cm or <5cm of the tumor still most or completely destroyed the role of heat.
