Clinical Study on Autologous Stromal Vascular Fraction(SVF) Treatment for Refractory Benign Airway Stenosis and Respiratory Tract Fistula

China20 participantsStarted 2022-03-20

Plain-language summary

Benign airway stenosis and respiratory tract fistula are common types of airway injury. The diseases occurred after endogenous and exogenous stimuli (tuberculosis, tumor, surgery, tracheal intubation) causing damage to the airway mucosa, resulting in scar repair and irreversible loss of airway epithelium. Autologous adipose vascular fraction (stromal vascular fraction, SVF) is a mixture of cells obtained from adipose tissue through digestion and centrifugation, containing a variety of cell types, such as mesenchymal cells, endothelial progenitor cells, endothelial cells, pericytes, and macrophages. Previous studies have shown that SVF can achieve regeneration and wound healing through modulating the immune microenvironment, promoting angiogenesis, thereby promoting endogenous regeneration of the in situ adult stem cells. This project utilizes the tissue repair function of autologous SVF to treat benign airway stenosis and respiratory tract fistula. To clarify the efficacy and safety of autologous SVF in the treatment of airway injury.
