目的通过临床总结,评价超声造影(CEUS)在射频消融治疗肝癌肝移植术后肝转移癌中应用的优点。方法采用超声造影辅助诊断定位经皮穿刺射频消融(RFA)治疗肝癌肝移植术后2～12月肝转移癌灶12例,癌灶直径12 mm～45 mm,每个病灶通过超声造影诊断定位进行RFA 1～2次,术后通过超声造影及增强CT评价疗效。结果11例病灶术后1月后复查,示全部消融,1例较大病灶治疗后有部分残余,行再次射频,1月后复查病灶坏死。结论超声造影应用于RFA治疗肝癌肝移植术后肝转移癌发现早,诊断早,定位准确,效果好,操作简便易行,微创无严重并发症,进一步提高了超声引导下RFA的准确率和疗效。
Objective To evaluate the advantages of CEUS in radiofrequency ablation of liver metastases after liver transplantation for liver cancer through clinical summary. Methods Twenty-two patients with hepatic metastases from 2 to 12 months after liver transplantation were treated with radiofrequency ablation (RFA) with contrast-enhanced ultrasound. The diameter of the lesion ranged from 12 mm to 45 mm. Each lesion was diagnosed by contrast-enhanced ultrasound RFA 1 or 2 times, after surgery by contrast-enhanced ultrasound and evaluation of efficacy. Results 11 cases of lesions after 1 month after the review, showed all ablation, a larger lesion after treatment, there are some residual RF line again after January review of focal necrosis. Conclusion The application of contrast-enhanced ultrasound in the treatment of liver cancer after liver transplantation with RFA has the advantages of early diagnosis, early diagnosis, accurate positioning, good effect, easy operation and minimally invasive minimally invasive complication, and further improves the accuracy of ultrasound-guided RFA Efficacy.
