Follow-up was obtained in all patients. <i>Results:<\/i> 62 UltraflexTM stents (covered = 51, uncovered = 11) were implanted in 60 patients. Diagnoses were bronchial carcinoma (n = 50), esophageal carcinoma (n = 3) and metastases (n = 7). Stents were inserted in the trachea (n = 5), main bronchi\/intermediate bronchus (n = 22), from main bronchi\/intermediate bronchus to lobar bronchi (n = 28) or in the lobar bronchi themselves (n = 7). Successful reopening of the stenoses and relief were achieved in all patients. There was no procedure-related mortality. Complications included mucous plugging in 8%, stenosing granulation tissue in 5%, tumor ingrowth in 5% and stent migration in 5% of patients. Using Kaplan-Meier estimates, the overall mean survival was 160 days (standard error: 30). Median survival was 91 days. The overall 3- and 6-month survival were 52 and 20%, respectively. Death (n = 59, 98%) was attributed mainly to disease progression with cachexia and metastases, pneumonia (n = 5, 10%), and hemoptysis (n = 1, 2%). <i>Conclusion:<\/i> UltraflexTM stents have a low complication rate and can be effectively used in complex malignant airway stenoseswith marked asymmetry or irregularity, angulation or changing diameters.<\/jats:p>","DOI":"10.1159\/000119053","type":"journal-article","created":{"date-parts":[[2008,5,13]],"date-time":"2008-05-13T13:14:29Z","timestamp":1210684469000},"page":"443-449","source":"Crossref","is-referenced-by-count":64,"title":["Long-Term Follow-Up and Survival after UltraflexTM Stent Insertion in the Management of Complex Malignant Airway Stenoses"],"prefix":"10.1159","volume":"75","author":[{"given":"Albrecht","family":"Breitenb\u00fccher","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Prashant N.","family":"Chhajed","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin H.","family":"Brutsche","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlo","family":"Mordasini","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Schilter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Tamm","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2008,3,20]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1183%2F09031936.02.00204602"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.123.5.1693"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.97.2.328"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097%2F00128594-199601000-00003"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.109.3.626"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.104.6.1653"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1055%2Fs-2007-1013675"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.110.5.1161"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1136%2Fthx.51.11.1127"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.124.5.1993"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.118.4.959"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.119.6.1910"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1440-1843.2003.00425.x"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1007%2Fs00330-003-2022-5"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.125.1.354-a"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016%2FS0003-4975%2801%2903460-9"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.athoracsur.2004.05.062"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.athoracsur.2006.11.066"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.127.6.2106"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.127.2.482"}],"container-title":["Respiration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/119053","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/119053","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T02:11:31Z","timestamp":1745460691000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000119053"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008]]},"references-count":20,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2008,5,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000119053","archive":["Portico"],"relation":{},"ISSN":["0025-7931","1423-0356"],"issn-type":[{"value":"0025-7931","type":"print"},{"value":"1423-0356","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008]]}}}
