ROSSI, Fabio Henrique et al. Effects of electrocautery to provoke endovascular thermal injury. Acta Cir. Bras. [online]. 2011, vol.26, n.5, pp. 329-332. ISSN 1678-2674. http://dx.doi.org/10.1590/S0102-86502011000500001.
PURPOSE: 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. CONCLUSION: 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.
