title: [Severing perforators in advanced stages of chronic venous insufficiency].
abstract: OBJECTIVE
  To evaluate the importance of anastomozing veins in the development of chronic venous insufficiency (CVI).
  
  
  METHODS
  Perspective analysis of a group of 82 extremities where the perforators were severed by the endoscopic or open method.
  
  
  RESULTS
  Surgery of the perforators was associated with a decline of the total number of perforators detectable on DUS, with a marked reduction of extremities with insufficient perforators and improved total CEAP score. In 98% extremities at the same time surgery of the epifascial venous system was performed.
  
  
  CONCLUSIONS
  The role of perforators in the development of CVI is not unequivocal and its assessment is more difficult due to concurrent operations of the epifascial system. Dissection of the perforators is indicated in cca one tenth of patients with CVI.
