What are the risks and what is the recovery like?

Common side effects include post-embolization syndrome—fever, abdominal pain, nausea, and fatigue—which typically resolves within a few days. More serious but less common risks include liver abscess, bile duct injury, hepatic failure, or non-target embolization. Recovery usually involves a hospital stay of 3–4 days for monitoring, followed by 1–2 weeks of rest at home. Most patients can resume normal activities within two weeks, though fatigue may persist. Regular follow-up imaging is required to assess tumor response.
