摘要
目的评价伽玛刀联合内支架植入术治疗肝癌合并下腔静脉瘤栓的疗效。方法对26例肝癌合并下腔静脉瘤栓患者,于内支架植入术后进行伽玛刀治疗下腔静脉瘤栓。定期行下腔静脉造影复查,了解下腔静脉通畅程度。结果治疗后,下腔静脉内径均有不同程度的扩大,支架植入后下腔静脉内径增大(0.842±0.283)cm,伽玛刀治疗后内径增大(1.523±0.195)cm。伽玛刀治疗后内径与支架植入前内径差异有统计学意义(P<0.01)。随访期至少达6个月,3、6个月下腔静脉通畅率均为100%。均未发生与内支架植入术和伽玛刀治疗相关的严重并发症。结论伽玛刀联合内支架植入术治疗肝癌合并下腔静脉瘤栓安全有效。
Objective To investigate the effectiveness of gamma-knife radiotherapy combined with stent placement for the treatment of cancerous thrombus in inferior vena cava （IVC） in patients with hepatic carcinoma. Methods Stent placement was performed in 26 patients of hepatic carcinoma associated with cancerous thrombus in IVC, which was followed by gamma-knife radiotherapy for the treatment of thrombus, IVC angiography was reexamined at regular intervals to find out the patent situation and to measure the internal diameter of IVC. Results The internal diameter of IVC was increased in different degree after the treatment. After stent placement the internal diameter of IVC was increased by （0.842± 0.283 ） cm, while the internal diameter of IVC was increased by （1.523 ±0.195） cm after gamma-knife radiotherapy. The internal diameter of IVC after gamma-knife radiotherapy was significantly greater than that before stent placement （P 〈 0.001）. The shortest follow-up time was 6 months. The patent rate of IVC at 3 and 6 months was 100% and 100% respectively. No serious complications related to stent placement or gamma-knife radiotherapy occurred. Conclusion Gamma-knife radiotherapy combined with stent placement is safe and effective for the treatment of cancerous thrombus in inferior vena cava in patients with hepatic carcinoma.
