Successful treatment of tracheal stenosis due to a broken uncovered metallic stent placed over 20 years ago in a patient with recurrent polychondritis using argon plasma coagulation and airway ballooning
Abstract
Abstract A woman in her mid‐60s with recurrent polychondritis was admitted to our hospital due to airway stenosis secondary to an uncovered metallic stent. She underwent a bronchoscopic intervention under general anaesthesia. During the procedure, the stent fracture was cauterized using Argon Plasma Coagulation (APC) cauterisation, performed with argon flow at 1 L/min and power set at 70 W. APC cauterisation caused the stent wire to flex circularly, gradually improving the stenosis. Tracheal dilatation was then performed using an airway balloon. Following the ballooning, a thin bronchoscope was easily passed through the lower trachea, and the left and right main bronchi were observed; therefore, the procedure was completed without any complications. APC coagulation and airway ballooning are viable choices for the temporary treatment of airway stenosis due to broken metallic stents.
