These appealing results in highly complex situations suggest the need to evaluate these devices in more common situations.\n\nIn this study we aim to test our new generation stents in all patients planned for airway stenting. After computer-assisted segmentation of airways (VGStudioMAX 3.0 software), the stenosis is virtually corrected, leading to the conception of a virtual stent (AnatomikModeling, Toulouse), allowing for the fabrication of a mold using a 3D printer. The stent is then built and sterilized (NOVATECH, Berlin) and inserted during rigid bronchoscopy.\n\nClose follow up is then conducted, including clinical evaluation after one week, three, six and 12 months; spirometry at one week, 3 months, 6 months and 12 months and chest CT-scan at one week.",[67],"Airway Disease",[69,70,71],"rigid bronchoscopy","3D computer-assisted fabrication","silicon-dedicated stent","2026-05-28",{"date":74,"type":75},"2026-06-01","ACTUAL",{"date":77,"type":75},"2021-06-17",{"date":79,"type":61},"2029-12-30",{"name":5,"class":6},1]
