Bloody Bronchial Cast Formation Due to Alveolar Hemorrhage Associated with H1N1 Influenza Infection.

Bloody Bronchial Cast Formation Due to Alveolar Hemorrhage Associated with H1N1 Influenza Infection. Intern Med. 2017 Sep 15;: Authors: Okada Y, Okada A, Narumiya H, Iiduka R, Katsura K Abstract A previously healthy 55-year-old man with H1N1 influenza A presented with severe respiratory failure and cardiac arrest. Following the return of spontaneous circulation, venovenous extracorporeal membrane oxygenation was required to maintain oxygenation. On day 2, bronchoscopy revealed a bloody bronchial cast obstructing the right main bronchus. A pathological examination revealed that it was composed of intrabronchial and intra-alveolar hemorrhagic tissue. Unfortunately, the patient died due to severe brain ischemia; a subsequent autopsy revealed marked alveolar hemorrhage. It is possible that anticoagulant therapy, alveolar collapse, and neuromuscular blocking agents provoked cast development in this case. PMID: 28924110 [PubMed - as supplied by publisher]
