摘要
目的:临床观察采用新型血管内射频消融(RFA)导管HabibTMVesOpen消融门静脉癌栓再通门静脉的安全性和疗效。方法15例肝癌合并门静脉癌栓并出现血流阻塞的患者,先在B型超声引导下经皮肝穿刺门静脉并置管;再在DSA引导下,将新型血管内RFA导管导引至门静脉癌栓处,连接射频发生器(RITA),设置功率10W消融治疗2-10min。评价手术成功率、术后并发症、肝肾功能及血常规改变、门静脉通畅及癌栓消融情况。结果所有患者均顺利完成手术,未发生如穿刺道出血、血管穿孔、胆汁瘘并发感染、肝脓肿、腹腔出血等并发症,RFA后直接门静脉造影显示局部门静脉再通;4周后复查肝功能、血常规无明显变化,超声多普勒检查提示原堵塞门静脉有血流通过,部分患者CT检查见门静脉癌栓缩小或消失。结论经皮穿刺门静脉RFA门静脉癌栓在技术上具有可行性,可能是治疗肝癌门静脉癌栓的一种有效方法。
Objective To investigate the safety and clinical effect of endovascular radiofrequency ablation (RFA) catheter, the HabibTM VesOpen, in treating portal vein tumor thrombus. Methods Fifteen patients of hepatocellular carcinoma associated with portal vein thrombus causing obstruction of blood flow were enrolled in this study. Guided by ultrasound percutaneous portal catheter implantation was performed, then, under DSA guidance RFA catheter was placed at portal vein tumor thrombus. RF generator (RITA) was connected to the electrodes, the power was set at 10 W for 2 - 10 minutes. The technical success rate, the postoperative complications, the hepatic and renal functions as well as routine blood tests, portal vein blood flow and the ablation extent of portal vein tumor thrombus were evaluated, and the results were analyzed. Results The procedure was successfully accomplished in all patients. No technique-related complications, such as hemorrhage, vessel perforation, bile leak complicated by infection, liver abscess, abdominal bleeding occurred. Direct portography performed immediately after RFA showed that the portal vein was re-opened. Laboratory examinations performed 4 weeks after RFA showed that no obvious changes in hepatic functions and routine blood tests were observed. Doppler ultrasound examinations revealed that flowing blood was obviously displayed within previously obstructed portal vein. CT scanning was carried out in some patients with portal vein thrombus, and it indicated that the portal vein tumor thrombus was reduced in size or even disappeared. Conclusion For the treatment of portal vein tumor thrombus in patients with hepatocellular carcinoma, endovascular radiofrequency ablation is technically feasible, and the initial results indicate that this technique is an effective treatment.
