Case in brief
This case series discusses the successful use of Y-90 radioembolization in patients with liver tumors that had aberrant arterial supply. The presence of nonhepatic arterial feeders often leads to the consideration of alternative treatments like TACE due to concerns about complications. However, the authors demonstrate that with careful management, radioembolization can be effectively performed in these cases, avoiding suboptimal therapy.
Diagnostic / clinical pearl
Clinicians should be aware that liver lesions may receive blood supply from aberrant extrahepatic arteries, which can impact treatment decisions and outcomes.
Why it matters
Recognizing and utilizing aberrant arterial supply for Y-90 radioembolization can expand treatment options for patients with complex hepatic vascular anatomy.
