超声引导经皮微波消融治疗特殊部位肝癌

目的 探讨超声引导经皮微波消融治疗特殊部位肝癌的可行性、有效性和安全性.方法 与大血管或肝周器官紧邻且无明显间距的病灶纳为特殊部位病灶,病灶直径≤3 cm.30例患者(39个病灶)在局麻下行超声引导的经皮微波消融治疗.治疗后观察患者有无并发症,行影像学及临床随访观察局部复发情况.结果 30例患者微波消融治疗操作均顺利完成.消融后,较严重并发症的发生率为6.7%(2/30),局部复发率为5.1%(2/39).结论 超声引导下对特殊部位肝癌行经皮微波消融治疗为安全、有效、可行的微创治疗,具有重要的临床意义.

Ultrasound-guided percutaneous microwave ablation of hepatic cancer in special parts

Objective To explore the feasibility,effectiveness and safety of percutaneous microwave ablation of hepatic cancer in special parts under ultrasound guidance.Methods Lesions adjacent to large vessels or perihepatic organs were defined as hepatic cancer in special parts,and the diameters of all lesions were less than or equal to 3 cm.A total of 30 patients with 39 nodules were proceeded by ultrasound-guided microwave ablation under local anesthesia.After treatment,the associated complications were observed,and the follow-up data of imaging and clinical indicators were investigated to assess local recurrence.Results The operations were completed successfully in all patients.The incidence of severe complications was 6.7%(2/30),and local tumor recurrence rate was 5.1%(2/39).Conclusion Ultrasound-guided percutaneous microwave ablation is a safe and effective method for treating hepatic cancer in special parts,which has important clinical value.
