Post-embolization Syndrome Following Yttrium-90 Radiation Segmentectomy.

Post-embolization syndrome (PES) is a complication that commonly occurs after treatment with transarterial embolization for hepatocellular carcinoma (HCC). Patients with PES often present with clinical symptoms such as fever, nausea, abdominal pain, and elevated liver enzymes typically 24-72 hours after the procedure. While cases of PES have been documented in patients treated with transarterial chemoembolization, here, we present an unusual case of delayed onset PES in a 70-year-old male with HCC following treatment with a form of transarterial radioembolization.
