Abstract: Potential complications arising from yttrium-90 (90Y) radioembolization are often related to inadvertent embolization of non-target vasculature during particle administration.Therefore,careful pretherapeutic planning with arterial mapping is especially important to help identify potential high-risk arteries and vascular communications.A complete pre-therapeutic evaluation of hepatic arterial vasculature includes selective arteriography,precautionary embolization of potential risk arteries and identification of occurrences of hepatopulmonary shunting secondary to tumor-related pathologic arteriovenous channels.The aim of this review is to discuss the pertinent arterial anatomy during 90Y radioembolization therapy and strategies on how to evaluate the risk and prevent the occurrence of non-target embolization through those vascular structures.
