Diffuse alveolar haemorrhage due to warfarin therapy has been rarely reported in the literature. In this paper, we describe the case of 62-year-old woman with a history of chronic atrial fibrillation treated with warfarin, who was admitted to our institution with haemoptysis and dyspnoea. Alveolar haemorrhage was suspected clinically and subsequently confirmed by bronchoscopy. The patient required aggressive treatment with fresh frozen plasma, vitamin K and mechanical ventilation with a successful outcome. We emphasise the need for early diagnosis and fast therapeutic intervention, especially with over-anticoagulation (INR &gt;9), in patients with this rare and potentially lethal condition.<\/jats:p>","DOI":"10.1136\/bcr.08.2008.0757","type":"journal-article","created":{"date-parts":[[2009,3,17]],"date-time":"2009-03-17T15:41:52Z","timestamp":1237304512000},"page":"bcr0820080757","source":"Crossref","is-referenced-by-count":14,"title":["Diffuse alveolar haemorrhage secondary to warfarin therapy for atrial fibrillation: a case report and literature review"],"prefix":"10.1136","volume":"2009","author":[{"given":"Abdelkarim","family":"Waness","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tarek","family":"Aldabbagh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Harakati","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2009,3,17]]},"reference":[{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.110.5.1305"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.2","first-page":"158","article-title":"Severe alveolar hemorrhage in Churg-Strauss syndrome","volume":"71","author":"Clutterbuck","year":"1987","journal-title":"Eur J Respir Dis"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.3","first-page":"137","article-title":"[Wegener granulomatosis with severe alveolar hemorrhagic syndrome] (in Romanian)","volume":"56","author":"Marci","year":"2007","journal-title":"Pneumologia"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.4","doi-asserted-by":"crossref","first-page":"47","DOI":"10.1590\/S0041-87812004000100008","article-title":"Pulmonary hemorrhage as a manifestation of systemic lupus erythematosus","volume":"59","author":"Santos","year":"2004","journal-title":"Rev Hosp Clin Fac Med Sao Paulo"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.5","first-page":"1454","article-title":"[Alveolar hemorrhage] (in German)","volume":"119","author":"Kronauer","year":"1989","journal-title":"Schweiz Med Wochenschr"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.6","doi-asserted-by":"publisher","DOI":"10.3346\/jkms.2007.22.6.1074"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.7","doi-asserted-by":"crossref","first-page":"42","DOI":"10.1053\/ajkd.2002.29876","article-title":"Pulmonary renal syndrome: a 4-year, single-center experience","volume":"39","author":"Gallagher","year":"2002","journal-title":"Am J Kidney Dis"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.8","doi-asserted-by":"crossref","first-page":"109","DOI":"10.1016\/S0761-8417(05)84796-0","article-title":"[Idiopathic pulmonary hemosiderosis in adults] (in French)","volume":"61","author":"Maalej","year":"2005","journal-title":"Rev Pneumol Clin"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.9","first-page":"17","article-title":"[Massive intra-alveolar hemorrhage in chronic idiopathic thrombocytopenic purpura] (in Hebrew)","volume":"115","author":"Potasman","year":"1988","journal-title":"Harefuah"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.10","first-page":"304","article-title":"[Alveolar hemorrhagic syndrome in sarcoidosis] (in German)","volume":"52","author":"Friesecke","year":"1998","journal-title":"Pneumologie"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.11","doi-asserted-by":"publisher","DOI":"10.1378\/chest.130.5.1612"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.12","doi-asserted-by":"publisher","DOI":"10.1157\/13111519"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.13","doi-asserted-by":"crossref","first-page":"697","DOI":"10.1183\/09031936.99.13369799","article-title":"Haemoptysis after breath-hold diving","volume":"3","author":"Boussuges","year":"1999","journal-title":"Eur Respir J"},{"key":"2025042507373439000_2009.mar08_1.bcr0820080757.14","first-page":"327","article-title":"Dissection of ascending aorta.
