During 2002\u20132006, we performed 1,800 FFBs on LTx patients at our center. &lt;i&gt;Objectives:&lt;\/i&gt; To describe the occurrence of bronchial mucosal bleeding during FFB in 5 patients. &lt;i&gt;Methods:&lt;\/i&gt; FFB was performed under sedation with propofol and after intubation with a laryngeal mask. All 5 patients had normal chest X-rays and no clinical signs of lower respiratory tract infection. They were normotensive, had normal lung function, normal platelet counts and prothrombin times and no clinical evidence of other coagulopathies. Immunosuppression consisted of cyclosporin A, azathioprine and prednisolone. &lt;i&gt;Results:&lt;\/i&gt; In these 5 patients, we observed diffuse bleeding from the bronchial mucosa in both the transplanted and native lung. Bleeding was preceded by coughing and the development of diffuse mucosal hyperemia followed by mucosal petechiae, which subsequently coalesced into mucosal hemorrhage and overt intrabronchial bleeding. In 1 case, the bleeding caused impairment of lung function and hypoxemia. &lt;i&gt;Conclusion:&lt;\/i&gt; Bronchial mucosal bleeding is probably caused by increased intrathoracic pressure induced by coughing in a closed airway system, which in turn induces a high pressure in the intrathoracic vessels that is transferred to the bronchial vascular system. Vulnerability of the mucosal capillaries due to immunosuppression probably also contributes to what we have termed \u2018the hemorrhagic bronchial mucosa syndrome\u2019. The hemorrhagic bronchial mucosa syndrome with intrabronchial bleeding is a rare complication of bronchoscopy, predominantly occurring in LTx patients. From a prophylactic point of view, it seems essential to avoid coughing during bronchoscopy in intubated patients.<\/jats:p>","DOI":"10.1159\/000209337","type":"journal-article","created":{"date-parts":[[2009,3,18]],"date-time":"2009-03-18T12:46:05Z","timestamp":1237380365000},"page":"416-419","source":"Crossref","is-referenced-by-count":2,"title":["Diffuse Bleeding from the Bronchial Mucosa on Flexible Bronchoscopy in Lung Transplanted Patients: \u2018The Hemorrhagic Bronchial Mucosa Syndrome\u2019"],"prefix":"10.1159","volume":"77","author":[{"given":"Nils","family":"Milman","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,3,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.healun.2005.03.001"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097%2FTP.0b013e3181641df9"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2FS1053-2498%2802%2900442-4"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.129.1_suppl.48S"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1378%2Fchest.126.4.1123"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1136%2Fthorax.56.4.279"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2FS0140-6736%2860%2992907-X"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1136%2Fard.35.2.148"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.healun.2006.09.013"}],"container-title":["Respiration"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/209337","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/209337","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T22:40:20Z","timestamp":1745448020000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000209337"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":9,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2009,5,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000209337","archive":["Portico"],"relation":{},"ISSN":["0025-7931","1423-0356"],"issn-type":[{"type":"print","value":"0025-7931"},{"type":"electronic","value":"1423-0356"}],"subject":[],"published":{"date-parts":[[2009]]}}}
