92例CT导向下射频消融治疗肝脏肿瘤--并发症观察处理与体会

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。

Treatment of liver tumors with CT-guided percutaneous radio-frequency ablation in 92 cases-complications encountered and managed

Objective To investigate the associated complication of hepatocellular carcinoma and liver metastasis with the treatment of radiofrequency ablation(RFA) and the safety of the CT-guided RFA. Methods 92 cases with 177 lesions received the intenvntional procedure of RFA including hepatocelluar carcinoma 53 cases and liver metastasis 49 cases.Every case underwent 1-4 times of RFA treatment consecutively and follow-up for 6-24 months respectively. Results There was no treatment-related mortality in the studied group.The major complications included subcapsular hemorrhage(2 cases),intra-tumor hemorrhage(2 cases),proceeding hypotension(1 case),acute pericardial effusion(1 case),transient liver decompensation(1 case),biloma(2 cases),thickening of diaphragm(1 case) local bile-duct dilated(3 cases),neoplastic seeding(1 case) Conclusions RFA is a safe minimal invasive method in the treatment of liver tumor under the guidance of CT,with lesser complications under careful observation and management.
