Core tip: Preoperative radioembolization may improve resectability of hepatocellular carcinoma in cirrhotic patient, inducing tumor downsizing, atrophy of radio-embolized sector and regeneration of non-embolized liver. We describe a patient with a segment IV hepatocellular carcinoma where the presence of two separated left hepatic arteries permitted to deliver sequentially high-dose 90Yttrium to the tumor and lower dose to future resected liver, allowing uneventful left hepatectomy 3 mo later. This observation suggests that, when different arterial accesses exist to tumor and future resected non-tumor liver, sequential radioembolization with different radiation doses could represent a new preoperative strategy, optimizing the tumoricidal effect while minimizing the risk of radiation-induced liver damage.
