目的分析原发性肝癌和肝转移瘤射频消融治疗的相关的并发症,了解经皮CT导向下的消融治疗的安全性。方法本组共分析了92例原发性肝癌和肝转移瘤患者,合计177个病灶,在CT导向下对病灶行射频消融治疗。每例患者均先后完成1~4次射频消融治疗,随访观察6~24个月。结果所治病例中未出现相关性死亡。射频消融治疗的主要并发症为肝被膜下出血3例,肿瘤内出血2例,进行性低血压1例,急性心包积液1例,一过性肝功能失代偿1例,胆汁瘤2例,肝内局限性胆管扩张3例,观察到肿瘤种植1例。结论CT导向下的消融治疗肝脏肿瘤是安全的治疗肝脏肿瘤的方法之一。通过密切观察、操作细心及时处理出现的情况将会减少并发症发生。
Objective To analyze the related complications of radiofrequency ablation of primary liver cancer and liver metastases and to understand the safety of percutaneous CT-guided ablation. Methods A total of 92 patients with primary liver cancer and liver metastases were analyzed in this study. A total of 177 lesions were treated with CT-guided radiofrequency ablation. Each patient has completed 1 to 4 radiofrequency ablation treatment, follow-up observation of 6 to 24 months. Results There were no related deaths in the treated cases. The main complications of radiofrequency ablation were 3 cases of hemorrhage under the liver capsule, 2 cases of intra-tumor hemorrhage, 1 case of progressive hypotension, 1 case of acute pericardial effusion, 1 case of transient hepatic decompensation, 2 cases of bile tumor, 3 cases of intrahepatic bile duct dilatation, observed in 1 case of tumor implantation. Conclusion CT guided ablation of liver tumors is one of the safe ways to treat liver tumors. By close observation, careful operation and timely treatment of the situation will reduce the incidence of complications.
