ABSTRACT
BACKGROUND:
Airway stenting may be needed to manage anastomotic complications in lung transplant recipients. Conventional stenting strategies may be inadequate due to anatomic variations between the recipient and donor or involvement of both the anastomosis and lobar bronchi.METHODS:
We investigated the efficacy of 3D-designed patient-specific silicone Y-stents in managing this scenario. 9 patients with complex airway stenosis underwent custom stent insertion after either failing traditional management strategies or having anatomy not suitable for conventional stents. CT images were uploaded to stent design software to make a virtual stent model. 3D printing technology was then used to make a mold for the final silicone stent which was implanted via rigid bronchoscopy. Forced expiratory volume in 1 s (FEV1) was measured pre- and post-stent placement.RESULTS:
78 % of patients experienced an increase in their FEV1 after stent insertion, (p = 0.001, 0.02 at 30 and 90 days respectively). Unplanned bronchoscopies primarily occurred due to mucous plugging. 2 patients had sufficient airway remodeling allowing for stent removal.CONCLUSIONS:
Personalized 3D-designed Y-stents demonstrate promising results for managing complicated airway stenosis, offering improved lung function and potential long-term benefits for lung transplant recipients.Palabras clave
