Locoregional treatment of hepatocellular carcinomas using yttrium-90 (Y-90) microspheres
is an emerging modality, and involves the administration of such radioactive particles
directly into the hepatic arterial vasculature. We present the case of a 58-year-old
gentleman undergoing evaluation for Y-90 microsphere therapy for hepatocellular carcinoma,
in which our findings suggest that significant hepatic arterial portal venous shunting
detected during the angiogram maybe a predictor of poor localization of microspheres
in the turmor, and that centers that utilize body surface area (BSA) approaches for
dosimetry should take note of such findings.
