摘要

Radiation segmentectomy(RS) is a new approach to90 Y radioembolization that has been designed to increase the safety and efficacy of radioembolization in patients with unresectable hepatic malignancies. With this technique,high doses(>190 Gy) of radiation are delivered to the tumor through radioembolization performed in a segmental fashion, potentially increasing the radiation dose to the tumor while minimizing injury to the liver parenchyma. The aim of this review is to provide a summary of the indications, device choice, dosimetry, procedure, clinical outcomes, and toxicity of RS based on the clinical series currently available.
