Patients with follow-ups of less than 3\u2009months and after heart\u2013lung transplantation were excluded. OAC was defined either as the need for stenting, surgical revision, or balloon dilatation. Outcome parameters included graft survival, graft function, quality of life, and management.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>During the study period, 1,170 patients were included. Hundred thirty-five (11.5%) patients developed OAC. Forty-six (4.4%) patients had significant bilateral OAC. Thirty-seven (80%) bilateral OAC patients were treated by stent insertion; in 34 patients, biodegradable stents were used. The median number of bronchoscopies in bilateral OAC was 26 during the first postoperative year compared with nine in controls ( p\u2009&lt;\u20090.001). Fourteen OAC patients ( n\u2009=\u200910 bilateral) underwent surgical revision including six re-do transplantations. Graft loss occurred significantly more frequently in patients with bilateral OAC with a graft survival of 63% and 50% in these after 3 and 5\u2009years compared with 83% and 73% in controls without OAC ( p\u2009&lt;\u20090.001). Baseline forced expiratory volume in 1\u2009s (FEV1) in patients with bilateral OAC was median 58% predicted in comparison with 90% in controls ( p\u2009&lt;\u20090.001). Quality of life was significantly reduced.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Bilateral OACs impose a high burden of disease on patients after lung transplantation and were associated with early and late graft loss. Affected patients\u2019 OAC demonstrated reduced graft function and impaired quality of life. Most OACs were managed by bronchoscopy preferably by non-permanent stenting. Surgery including re-do transplantation was used in selected cases.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/17534666231181541","type":"journal-article","created":{"date-parts":[[2023,8,1]],"date-time":"2023-08-01T07:20:02Z","timestamp":1690874402000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Management and outcome of obstructive airway complications after lung transplantation \u2013 a 12-year retrospective cohort study"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9540-9022","authenticated-orcid":false,"given":"Jens","family":"Gottlieb","sequence":"first","affiliation":[{"name":"Department of Respiratory Medicine and Infectious Diseases OE 6870, Hannover Medical School (Medizinische Hochschule Hannover, MHH), Carl Neuberg Strasse 1, 30625 Hannover, Germany.
