目的探讨螺旋CT对原发性小肝癌射频消融术后的随访价值。方法选取2011年8月至2012年4月间上海中医药大学附属第七人民医院收治的行超声引导下经皮穿刺射频消融治疗的96例肝脏恶性肿瘤患者,包括69例原发性小肝癌和27例转移性小肝癌,定期进行螺旋CT双期增强扫描检查和MRI检查,观察射频消融的效果及肿瘤复发的情况。结果射频消融术后1个月螺旋CT复查,肿瘤完全坏死者64例(66.7%)肿瘤残留者18例(18.8%)。2例因故未作螺旋CT复查。射频消融术后3个月螺旋CT复查肝内肿瘤复发者12例(12.5%),其中6例为原位复发(6.3%)。与同期MRI检查结果比较,差异无统计学意义(P>0.05)。结论螺旋CT能对原发性小肝癌患者射频消融术治疗后的病灶变化进行监测和评价,在患者术后随访评价中具有重要的临床价值。
Objective To investigate the follow-up value of spiral CT in radiofrequency ablation of primary small hepatocellular carcinoma. Methods From August 2011 to April 2012, we collected 96 cases of malignant liver tumors undergoing percutaneous radiofrequency ablation guided by ultrasound-guided seventh People’s Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, including 69 cases of primary small hepatocellular carcinoma and Twenty-seven patients with metastatic small hepatocellular carcinoma underwent spiral CT dual-phase enhanced MRI and MRI examination regularly to observe the radiofrequency ablation and tumor recurrence. Results One month after radiofrequency ablation, spiral CT was performed. Among 64 patients (66.7%) with tumor necrosis, 18 (18.8%) had residual tumor. 2 cases for no reason for spiral CT review. Three months after radiofrequency ablation, 12 (12.5%) patients had recurrent intrahepatic tumors by spiral CT, of which 6 were in situ (6.3%). Compared with the results of MRI examination at the same period, the difference was not statistically significant (P> 0.05). Conclusion Spiral CT can monitor and evaluate the changes of lesions after radiofrequency catheter ablation in patients with primary small hepatocellular carcinoma and has important clinical value in the postoperative follow-up evaluation.
