集束电极射频治疗肝恶性肿瘤疗效和并发症的CT评价

Evaluation of the effects and complications of hepatic carcinoma treated by cluster electrode RF through CT scanning

目的 探讨经皮射频消融术 (RFA)治疗肝肿瘤CT检查的价值。方法 回顾性地分析 5 0例肝肿瘤 (原发性肝癌 36例 ,肝转移癌 14例 )共 76个病灶RFA术前和术后复查随访CT表现 ,CT检查分别于治疗后 1、3周及以后间隔 3～ 6个月不等进行 ,均采用平扫和增强扫描。结果 获得完全消融的病灶为 35例 49个 (6 4.5 % ) ,不完全消融的病灶为 18例 2 7个 (35 .5 % )。经RFA治疗的 76个病灶中 9个出现病灶内出血 ;1个发生脓肿 ;3例出现腹腔内出血 ;6例发生右侧反应性胸腔积液和 1例出现少量气胸。

Objective To investigate CT examination in the evaluation of the percutaneous radio frequency ablation (RFA) in the treatment of hepatic carcinoma.Methods 50 cases of hepatic carcinoma (including primary hepatic cancer 36 and hepatic metastases 14) with 76 lesions treated by RFA associated with pre and post procedure data of CT follow up were analyzed retrospectively. CT examinations including plain and contrast enhanced CT scanning were carried out at 1 week and 3 weeks after the RFA, but sometimes with furthermore intermittent scanning at 3～6 months. Results Complete ablation of the tumors occurred in 49 lesions (64.5%) of 35 cases and incomplete ablation of tumors happened in 27 lesions (35.5%) of 18 cases. Among RFA treated 76 lesions, there were 9 with internal hemorrhage, 1 with abscess formation. 3 cases showed intraperitoneal bleeding; 6 cases demonstrated reactive pleural effusion and 1 case revealed with small amount of pneumothorx.Conclusions The contrast enhanced CT scanning provides a great diagnostic value for evaluation of the efficacy of hepatic tumor treated by RFA and also the local recurrence and complications.
