A 94-year-old woman presents to the emergency department in 2010 for progressive dyspnea and stridor over a period of 3 weeks. Thoracic computed tomography scan shows tracheal stenosis >50% (Fig. 1a) and generalized ectasia of the thoracic aorta (Fig. 1b). Bronchofibroscopy showed extrinsic compression of the lateral and anterior left wall of the trachea, 2cm from vocal chords, and 3cm in extension. Tracheal stenting (HOOD BSP-1430-M-S®) with rigid bronchoscope was successfully performed. Seven years later (missed follow-up visits) she is again admitted to the emergency department due to respiratory infection. A reassessment bronchofibroscopy was performed revealing a well implanted stent, 1cm from the vocal chords (Fig. 1c – proximal view from vocal chords) with discrete granulation tissue in the left lateral wall of the trachea (Fig. 1d – distal view). Stents can cause long-term complications including excess granulation tissue, migration, recurrent infections or even stent fracture.1 Most stents are intended for palliative purposes and there is no abundance of data on the longevity of these devices. This case describes an unexpected stent duration (total of 7 years) without major complications. The endoscopic approach allowed significant and lasting symptomatic relief and reduction in morbidity.
