目的评价在CT引导下经皮肝穿刺局部消融治疗肝脏特殊位置恶性肿瘤的临床应用价值。方法 36例肝脏恶性肿瘤患者,共有45枚肿瘤,所有患者肿瘤数目≤3个,直径≤3 cm,分别位于心脏大血管旁、近膈面、肝门部、肝包膜下、胆囊旁以及结肠旁等肝内特殊部位。使用方法包括微波、射频及无水酒精消融术,根据情况选择单一或联合应用治疗方法 ,随访12~84个月,观察并发症和疗效。结果所有患者45枚肿瘤,其中8枚进行了微波治疗,20枚进行了射频治疗,10枚进行无水酒精局部注射治疗,7枚进行了射频联合无水酒精局部注射治疗。未出现任何严重并发症。45枚肿瘤均完全坏死。结论本组研究结果表明,肝脏特殊位置恶性肿瘤数目≤3个,直径≤3 cm,根据情况选择方案进行CT引导局部消融治疗是一种安全、可行、有效的治疗方法。
Objective To evaluate the clinical value of percutaneous liver biopsies in the treatment of malignant tumors with special location in liver under the guidance of CT. Methods Thirty-six patients with malignant liver tumors, including 45 tumors, all had ≤3 tumors and ≤3 cm in diameter. Next to the liver and other special parts. Methods of use include microwave, radio frequency and anhydrous alcohol ablation, according to the situation to choose a single or combined application of treatment, followed up for 12 to 84 months, observe the complications and curative effect. Results Forty-five tumors in all patients, including 8 with microwave treatment, 20 with radiofrequency ablation, 10 with topical alcohol-free alcohol injection, and 7 with radio-frequency combined with local injection of anhydrous alcohol. No serious complications occurred. All 45 tumors were completely necrotic. Conclusion The results of this study show that the number of malignant tumors in the special liver area is less than 3 and the diameter is less than 3 cm. It is a safe, feasible and effective treatment for CT-guided local ablation according to the situation selection plan.
