Factors Leading to Obstructive Granulation Tissue Formation after Ultraflex Stenting in Benign Tracheal Narrowing

Abstract

Obstructive granulation tissue formation is not uncommon after SEMS implantation and structural airway obstruction prior to SEMS implantation is an independent predictor. Although SEMS implantation should be restricted to a select population, it may be placed in patients not suitable for surgical intervention or rigid bronchoscopy with anesthesia because of poor pulmonary function.
