Similar to transarterial chemoembolization (TACE), postembolization syndrome is one of the commonest side effects of<unk> . It consists of pain, fever, nausea, and vomiting. PES should be considered a side effect and not a complication of embolotherapy. It can be thought of as a type of tumor lysis syndrome. After abrupt ischemic tumor cell death, the tumor cells lyse and release their intracellular material into the bloodstream. PES is treated with analgesics, antipyretics, and antiemetics and typically subsides after 24–72 hours. Liver abscess is a rare complication of hepatic<unk> , so the typical post-embolzation appearance of a low density lesson with scattered gas bubbles should not be confused with liver abscess. It is seen most commonly in patient who have undergone bilioenteric bypass or who for any reason do not have an intact sphincter of Oddi. In a review of almost 1000 patients undergoing over 2000<unk>  procedures, the risk of liver abscess in patients with a contaminated biliary tree was found to be 300 times higher than the baseline risk. Non-target<unk>  is one of the most dreaded complications of hepatic embolotherapy but occurs infrequently when strict attention is paid to arterial anatomy. The gallbladder is commonly the most commonly involved non-target organ. Inadvertent gallbladder<unk>  results in prolonged PES with fever, pain, and nau-sea and vomiting. After<unk> , patients are observed in the post-anesthesia care unit for several hours. Patients are discharged from the hospital when taking adequate nutrition by mouth, when pain is adequately controlled with oral narcotics and when the temperature is lower than 38.5 for 24 hours.
