摘要
目的:探讨CT引导下弯针穿刺乙醇消融术(PEI)在小肝癌、肝动脉化疗栓塞(TACE)后残存活性病灶及转移性肝癌治疗中的价值。方法:37个小肝癌,25个经TACE治疗后的肝癌残存活性病灶,18个微小转移性肝癌病灶,采用CT引导下弯针穿刺无水乙醇肿瘤消融治疗,观察其坏死情况。结果:PEI治疗后一个疗程行动态增强MR或CT复查,37个小肝癌完全坏死率为86.5%,25个经TACE治疗后的残存肝癌完全坏死率为68.0%,18个微小转移性肝癌病灶完全坏死率为94.4%。结论:CT引导下无水乙醇消融术治疗肝脏肿瘤疗效较满意,弯针穿刺技术尤其有助于微小、深在病灶或需多点注射的病灶的治疗。
Objective To validate the therapeutic effect of CT-guided curve-needle percutaneous ethanol injection （CNPEI） for the treatment of small liver cancer, residual active foci after transcatheter hepatic arterial chemoembilization （TACE） and metastatic liver cancer. Methods 37 patients with small liver cancer, 25 patients with residual active foci after TACE, and 18 patients with micro metastatic liver cancer foci were treated with CNPEI, in whom necrosis of the tumors was observed. Results Dynamic enhanced MR or CT re-examination after a course of CNPEI showed that 86.5% of the 37 small liver cancers, 68.0% of the 25 residual active foci after TACE and 94.4% of the 18 micro metastatic liver cancer foci were necrotized completely. Conclusion The therapeutic effect of CT-guided CNPEI is satisfactory. Curve-needle puncture technique is especially helpful in the treatment of small and deep foci or foci that need multiple injections.
