Platelet-rich plasma(PRP), is a concentrate of platelet-rich plasma protein derived from whole blood. The main components of it are platelets, leukocytes and fibrin. Autologous PRP treatment can avoid the immune rejection caused by exogenous growth factor and the spread of disease. Evidence of the efficacy and safety of PRP has been proven in many studies. Tracheobronchial fistula(TBF) refers to a pathological state in which there are abnormal passages between the trachea, bronchi and chest, esophagus, stomach, mediastinum, bile ducts and other organs or cavities. Bronchopleural fistulas and tracheobronchioesophageal fistulas are two common types og TBF, which are mainly manifested as choking on eating and repeated aspiration pneumonia. Respiratory intervention has become one of the most common treatments to fight the disease. Although the short-term occlusion effect of conventional treatment methods of respiratory intervention is relatively easy to achieve, there is great uncertainty in the long-term treatment effect, and long-term large fistulas have little chance of healing. PRP has shown significant efficacy for hyperplastic scar of skin. Correspondingly, PRP will be applied as treatment of TBF to cure fistula.
