Intrahepatic flow diversion prior to segmental Yttrium-90 radioembolization for challenging tumor vasculature.

Background: Hepatic tumors with complex vascular supply or poor relative perfusion are prone to decreased rates of objective response. This is compounded in the setting of Yttrium-90 (Y90) transarterial radioembolization (TARE), which is minimally embolic and flow-dependent, relying on high threshold dose for complete response.

Objective: We describe our experience with intrahepatic flow diversion (FD) prior to TARE of hepatocellular carcinoma (HCC) with challenging vascular supply.

Survival Analysis Using Albumin-Bilirubin (ALBI) Grade for Patients Treated with Drug-Eluting Embolic Transarterial Chemoembolization for Hepatocellular Carcinoma.
