Y-90 radioembolisation is a relatively safe procedure. The most common complication is a post-radioembolisation syndrome, which occurs in around 50% of patients. Symptoms include fatigue, low-grade fever, nausea, vomiting and abdominal discomfort.
Less common complications include a build-up of fluid, high levels of alkaline phosphatase and infection. You may also experience stomach ulcers, inflammation of the pancreas, raised blood pressure, gallbladder inflammation or pneumonia. As with all percutaneous procedures, there is a risk of bleeding or damage to a blood vessel.
In some cases, patients react to the iodinated contrast materials used in the procedure, experiencing allergic reactions and harmful effects on the kidneys.
