The radiation segmentectomy technique may be defined as the administration of transarterial radioembolization delivered to 1 or 2 hepatic segments with the intention of segmental tissue ablation. Since first being described in 2011, radiation segmentectomy has quickly gained acceptance as a safe, effective, and potentially curative outpatient treatment for selected lower stage hepatocellular carcinomas. We describe our recommended techniques for radiation segmentectomy with glass or resin radiomicrospheres, including patient selection, dosimetry, microcatheter techniques, and clinical and imaging follow-up, accompanied by a brief review of the radiation segmentectomy literature. Radiation lobectomy, defined as the ablation of an entire hepatic lobe via transarterial radioembolization, is an area of growing interest in many centers. We also review the existing radiation lobectomy literature and suggest which patient and tumor factors may be associated with higher likelihood of successful treatment.
放射性节段切除术技术可定义为经动脉放射性栓塞术应用于1或2个肝段，旨在实现节段性组织消融。自2011年首次被描述以来，放射性节段切除术已迅速被认可为一种针对特定较低分期肝细胞癌的安全、有效且可能治愈的门诊治疗方法。我们描述了使用玻璃或树脂放射性微球进行放射性节段切除术的推荐技术，包括患者选择、剂量测定、微导管技术以及临床和影像学随访，并对放射性节段切除术的文献进行了简要回顾。放射性肝叶切除术定义为通过经动脉放射性栓塞术消融整个肝叶，在许多中心是一个越来越受关注的领域。我们还回顾了现有的放射性肝叶切除术文献，并指出哪些患者和肿瘤因素可能与更高的成功治疗可能性相关。
