Abstract

Identification of nontarget arteries is crucial prior to Yttrium-90 microspheres radioembolization. We present a case where an uncommon nontarget artery, the hepatic falciform artery was identified during work up for radioembolization and necessary preventive measures were taken to minimize the complications.

Keywords: Extrahepatic perfusion; MAA lung perfusion scan; hepatic falciform artery; nontarget artery; radioembolization.
