3D打印技术用于治疗肿瘤,精准进行碘粒子植入

2016-04-01 MedSci MedSci原创

东南大学附属中大医院介入与血管外科郭金和教授团队,在为肿瘤患者施行碘粒子介入治疗时,首次用上了3D打印模板技术,2位接受这一新型组合技术治疗的患者,不仅手术时间明显缩短、痛苦减少,而且治疗的精准度显著提高。据介绍,72岁的赵大爷食管癌术后4年,最近出现进食困难、吞咽吃力,并伴有呕吐恶心、腹部不适等症状,经过检查,发现赵大爷发生了肝门部淋巴结转移。另一位65岁的患者李大爷肺癌术后一个月,出现胸闷伴呼

东南大学附属中大医院介入与血管外科郭金和教授团队,在为肿瘤患者施行碘粒子介入治疗时,首次用上了3D打印模板技术,2位接受这一新型组合技术治疗的患者,不仅手术时间明显缩短、痛苦减少,而且治疗的精准度显著提高。

据介绍,72岁的赵大爷食管癌术后4年,最近出现进食困难、吞咽吃力,并伴有呕吐恶心、腹部不适等症状,经过检查,发现赵大爷发生了肝门部淋巴结转移。另一位65岁的患者李大爷肺癌术后一个月,出现胸闷伴呼吸困难,确诊为多处静脉血栓形成。两位患者需要接受该院介入与血管外专家碘粒子植入介入手术治疗。

中大医院介入与血管外科副主任郭金和教授介绍,考虑到赵大爷的年龄和身体状态,经过家属同意,决定对赵大爷肝脏部位的病灶进行碘粒子植入术,为使治疗更加精准,专家们首次引入3D打印模板技术。“没有3D模板以前,医生是通过CT逐层、多次扫描判断病灶的位置,手术时间长、准确度也受到一定影响。”郭金和教授说,有了3D打印技术,定位都是三维立体的,从平面布点到纵向深浅,再到粒子的剂量,都是经过精确计算的,可以避开血管、神经和骨骼。用3D打印模板做碘粒子植入手术,能提高布控和操作上的精准度,缩短手术时间、减少病人痛苦。赵大爷的手术仅持续了一个小时,医生为其共植入40颗碘粒子,这些粒子分布均匀、无病灶外游离,整个过程十分顺利。

目前,术后两位患者恢复良好,目前正在进一步康复中。
