Common etiologies include bronchiectasis, tumors, tuberculosis, aspergilloma, and cystic fibrosis. Approximately 20% of hemoptysis cases are categorized as cryptogenic. We conducted a retrospective observational study to understand the clinical characteristics of patients with cryptogenic hemoptysis (CH).<h4>Methods</h4>The clinical characteristics, angiographic findings, and immediate and long-term efficacies of BAE were retrospectively analyzed in 36 consecutive patients between January 2010 and December 2022.
