Utilidad del plasma rico en plaquetas en neumología

Abstract

The use of Platelet-rich plasma (PRP) involves a very complex network of molecular effects favoring tissue regeneration, due the presence of multiple mediators and growth factors. There are several communications about its use on the dental implantology field, plastic surgery and orthpedics. Besides, its utility has been suggested on peripheral nerves regeneration after trauma. In this article we present our experience on the use of PRP on acute injury of the respiratory system. We present a clinical series of 8 patients treated with PRP with positive response. Four of them presenting a massive hemoptysis were treated by direct endoscopic instillation of autologous PRP on the site of lesion; an immediate favorable result was obtained in all of them, without recurrence of bleeding on the follow-up period. A fifth case was a HIV seropositive patient with a spontaneous pneumothorax on intersticial pneumonia. He was treated by direct instillation of PRP through a thoracic tube. Full lung reexpansion was achieved within 72 h. Finally two patients with a respiratory fistula and another patient who suffered a traumatic tracheal rupture were treated with PRP endoscopic instillation, all of them with favorable clinical outcome. The use of autologous products as PRP has shown a good performance in all the clinical situations described, proposing it as a potentially very useful technique, particularly when a minimally invasive approach is required.
