摘要目的 探讨腔内植入125I粒子条及支架联合经动脉化疗栓塞(TACE)治疗原发性肝癌合并门脉主干癌栓的疗效.方法 采用腔内植入125I粒子条及支架联合TACE治疗50例肝癌合并门脉主干癌栓患者,并进行随访.结果 腔内共植入支架53枚,每例患者平均植入125I粒子15.8枚.技术成功率为100%,无严重的并发症.50例患者共接受137次TACE治疗,平均每例患者2.7次.肝内病灶客观缓解率为34.4%.50例患者平均生存期为370.1 d,中位生存期为223.0 d,术后90、180、360 d累积生存率分别为97.5%、59.3%和38.4%.支架平均通畅期为524.2 d,中位通畅期为407.4 d,术后90、180、360 d支架累积通畅率分别为94.9%、75.2%和64.5%.结论 腔内植入125I粒子条及支架联合TACE是治疗肝癌合并门脉主干癌栓的有效手段.

abstractsObjective To evaluate the therapeutic effect of endovascular placement of iodine-125 seed strand and stent combined with transcatheter arterial chemoembolization (TACE) to treat hepatocellular carcinoma (HCC) with tumor thrombus in the main portal vein (MPVTT). Methods Fifty patients with HCC complicated by MPVTT were enrolled into this study. There were 46 men and 4 women with a mean age of 53.9 years. TACE was performed after the iodine-125 seed strand and self-expandable stent placement in the obstructed segment of the main portal vein (MPV). Results Technical success rate was 100% for placement of iodine-125 seed strand and stent in the target segment of MPV. No serious procedure-related complications occurred. The mean follow-up duration was 208. 5 d. The mean and median survival time was 370.1 d and 223.0 d, respectively. The 90-, 180-, 360-day cumulative survival rates were 97.5%, 59.3%, and 38.4%, respectively. The mean and median patent time of stent was 524.2 d and 407.4 d, respectively. The 90-, 180-, 360-day cumulative patency rates of stent were 94.9%, 75.2%, and 64.5%, respectively. Conclusion Endovascular placement of iodine-125 seed strand and stent combined with TACE is an effective therapy for HCC with tumor thrombus in the main portal vein.
