Post-embolization syndrome is a series of manifestations such as right upper abdominal pain, fever, fatigue, nausea and vomiting after hepatic artery embolization. The definition of the so-called post-embolization syndrome is not very clear, including fever over 38c°? Is pain defined as the need for pain medication for more than a week? … The definition is not uniform and the reported incidence is highly variable. The presence of post-embolization syndrome in patients after interventional procedures is associated with the initial diameter of the tumor, the dose of chemotherapy, the patient’s physical condition, and the number of embolizations. It is thought to be related to the release of substances associated with necrosis and damage to adjacent normal liver tissue.
