title: [Radiofrequency ablation of hepatic metastases: clinical results].
abstract: OBJECTIVE
  To establish the effectiveness of radiofrequency ablation in the treatment of metastatic hepatic lesions.
  
  
  METHODS
  104 pts with 231 metastases were treated with RFA. The volume of achieved destruction was assessed using imaging method and cytology. Patients were followed-up for 1-37 months.
  
  
  RESULTS
  87.3% of metastases < 3.0 cm, 50.9% of tumors sized 3.0-5.0 cm and 14.3% of metastases > 5.0 cm were completely destroyed. Major complications occurred in 7.5% of the patients. 34% of the ablated tumors recurred.
  
  
  CONCLUSIONS
  The effectiveness of RFA metastases depends on the size and location of the lesion. Lesions adjacent to the gallblader and main bile ducts are risky for manipulation.
