abstract: OBJECTIVE
  To sum up causes and the prevention of complications after using the radio frequency ablation (RFA) to treat of primary and secondary liver cancers.
  
  
  METHODS
  The clinical courses of 735 patients, undergoing percutaneous RFA treatment for a total of 1780 times were reviewed. The causes of the complications occurring after the RFA treatment, and their prevention and treatment were evaluated.
  
  
  RESULTS
  Eleven complications after RFA treatment were found. Postoperative fever, sweating, and local pain were common. Serious complications, such as gut perforation, intraabdominal hemorrhage, and cardiovascular accident were found in 4 patients, and the mortality was 75%.
  
  
  CONCLUSIONS
  The RFA treatment is an effective method for the treatment of primary and secondary liver tumor. Careful selection of patients, appropriate preoperative preparations, proper operative procedures, and suitable postoperative care are the key points in preventing the complications.
