COLMENARES-ROLDAN, Gabriel Jaime  and  HOYOS-PALACIO, Lina Marcela. Bioresorbable bronchial stents and factors that affect the rate of degradation. CES Med. [online]. 2018, vol.32, n.3, pp.250-258. ISSN 0120-8705.

The causes that can lead to obstruction of the central airway can be of functional origin, due to obstruction of the light, organic parietal lesion or extrinsic compression; in turn, they can also be grouped into malignant and non-malignant obstructions. When an obstruction reduces more than 50% of the lumen of the airway causes debilitating symptoms and is an indication to implant a bronchial stent. The bronchial stents currently available are an incomplete solution for obstructions of the airways. On the other hand, an ideal bronchial stent must comply with many characteristics, such as being biocompatible, in many cases bioabsorbable, radio opaque, that does not generate an inflammatory reaction, having characteristics similar to those of the airway to decrease the accumulation of secretions, between others. For this reason, bioabsorbable bronchial stents are presented as an attractive alternative that offers certain advantages, although they are still in development. This article seeks to describe the advances around the bioabsorbable bronchial stents and the factors that affect the degradation of the polymers with which they have been manufactured.
