目的：报道1例行超声引导经皮穿刺125 I 放射性粒子植入术治疗肝门区肝癌病例，并文献复习。方法：术前对患者行CT及超声检查并制定术前放射治疗计划系统（TPS）计划，在超声引导下以平行的方式进针将粒子植入肿瘤内（粒子间的距离为1.0～1.5 cm），使患者肿瘤内的粒子分布符合 TPS计划。结果：手术过程顺利完成；术后1个月的随访过程中，无术后并发症；术后1个月行超声和CT检查，肿瘤体积明显缩小，肿瘤局部治疗效果良好。结论：超声引导经皮穿刺125 I放射性粒子植入术是治疗肝门区肝癌安全、有效的方法。%Objective:To report one case of hilar hepatic tumor treated by ultrasound-guided percutaneous puncture 125 I radioactive seed implantation,and to review the associated literatures.Methods:One patient’s CT and ultrasonic examinations were taken,and the plan of TPS was taken.The patient was treated by ultrasound-guided percutaneous puncture 125 I radioactive seed implantation according to the plan of TPS.The needles were parallel, and the distance between the seeds were 1.0 to 1.5 cm. Results:The operation was successfully completed.No postoperative complications were encountered during 1 month follow up.The volume of tumor was obviously reduced 1 month after operation detected by ultrasound and CT. The local control effect of tumor was good.Conclusion:Ultrasound-guided percutaneous puncture 125 I radioactive seed implantation is a safe and effective method in treating hilar hepatic tumor.
