近年来为提高抗肿瘤的疗效和减缓对周围正常肝组织的不良影响,开发了只向肿瘤所在亚肝段或肝段注入抗癌药物与碘油的混合液的超选择性亚肝段或肝段化疗栓塞术(Segmental Lp-TAE)。从手术病例的病理组织学研究和非手术病例的疗效观察来看,本法的临床价值已得到确认。现简要介绍如下。一、技术发展与基本手段因纤细而且尖端柔软的超选择血管造影用导丝及导管的开发和手技的进步,即便是迂曲蛇行的肝动脉分枝,也可较安全而容易地插入
In recent years, in order to improve antitumor efficacy and reduce adverse effects on surrounding normal liver tissues, a superselective sub-segment or liver has been developed in which only a mixture of anti-cancer drugs and lipiodol is injected into the sub-segment or liver segment of the tumor. Segmental chemoembolization (Segmental Lp-TAE). From the histopathological study of surgical cases and the observation of the efficacy of non-surgical cases, the clinical value of this method has been confirmed. The brief introduction is as follows. First, technological development and basic methods. Due to the development of fine and flexible super-selective guidewires and catheters for angiographic imaging, even the meandering of hepatic artery branches can be safely and easily inserted.
