title: Effects of electrocautery to provoke endovascular thermal injury.
abstract: OBJECTIVE
  To investigate the effects of a new electrocautery device to provoke endovascular venous thermal injury.
  
  
  METHODS
  An experimental endovascular electrocautery was placed inside eight ex-vivo bovine saphenous veins models. Each one was divided in eight segments and progressive intensities of electric energy liberated. The macroscopic and microscopic effects were analyzed.
  
  
  RESULTS
  Forty bovine saphenous veins segments were studied. The higher the electric energy applied the greater the nuclear picnosis and more intense the cytoplasmatic shrinkage and electrocoagulation effects.
  
  
  CONCLUSIONS
  The experimental endovascular electrocautery device demonstrated to be both capable of inducing the destruction of the intimal layers of the studied vein model and provoke endovascular thermal injury.
