Abstract
Radiation segmentectomy is an yttrium-90 transarterial radioembolization treatment
where a high radiation dose is administered to a small volume of liver to achieve
a high tumoricidal dose to a target with anatomic surgical precision while sparing
surrounding parenchyma. This therapeutic modality is often used to treat hepatocellular
carcinoma, and recent studies have demonstrated that radiation segmentectomy is an
effective treatment as a neoadjuvant to transplant, resection, or as a standalone
treatment. This article provides a review of radiation segmentectomy, indications
for treatment, recent outcome data, and guidelines for postprocedural management.
