冷循环射频消融治疗肝转移瘤的临床应用

目的探讨CT导向冷循环射频消融(RFA)在肝转移瘤治疗中的价值。方法回顾性分析2009年5月～2011年3月在CT导向下射频消融治疗的32例共48个肝转移瘤患者的临床资料,其中,肝转移瘤直径<3cm的20个,3～5cm的23个,>5cm的5个。所有患者术后1、3个月后行腹部CT三期扫描检查评价肿瘤疗效。结果 32例患者均顺利完成RFA治疗。RFA治疗后完全坏死肿瘤39个(81%),其中直径<3cm者19个(95%),3～5cm者18个(78.2%),>5cm者2个(40%),全部患者无严重并发症,无围手术期死亡。结论 CT导向下射频消融是一种安全、有效、创伤小、耐受性好的局部治疗肝转移瘤的方法。

Objective To investigate the value of CT-guided cool-trip radiofrequency ablation（RFA） in the treatment of liver metastasis. Methods Treated with CT-guided RFA form May 2009 to March 2011,the clinical data of 32 patients with 48 liver metastases was analyzed retrospectively. Among 48 lesions,the diameter of the lesion 3cm,3～5cm and 5cm was determined in 20,23 and 5 respectively. 1 month and 3 months after the procedure,postoperative checkup with CT tri-phase scanning was conducted in all patients to evaluate therapeutic results. The change of tumor size was observed .Results CT-guided RFA was successfully accomplished in all patients and 39（81%） lesions were completely ablated,of which 19 tumors（95%） were small than 3cm in diameter,18（78.2%） had a diameter between 3cm and 5cm,2（40%） tumor was less than 5cm. During the operation,no serious complications,perioperative deaths occurred. Conclusion In the treatment of liver metastasis,CT-guided radiofrequency ablation is an effective,safe local treatment with less trauma and better tolerance.
