Current Trends and Evidence on Post-Thoracic Endovascular Aortic Repair Aorto-Pulmonary and -Bronchial Fistula: A Narrative Review

Background: Aorto-bronchial or aorto-pulmonary fistulas (ABPF) are a rare but life-threatening complication following thoracic endovascular aortic repair (TEVAR). This narrative review aims to provide an overview of the current trends and available evidence on ABPF following TEVAR, evaluating risk factors, diagnostic approaches, and possible preventive and therapeutic strategies. Methods: Relevant publications on post-TEVAR ABPF were selected through a literature search on PubMed. Studies providing data on post-TEVAR ABPF concerning pathogenesis, clinical presentation, diagnostic tools, surgical approaches, and outcomes were included. Results: The literature search obtained 169 articles. After selection, 37 studies, published between 2000 and 2024, remained for analysis. The primary symptom of ABPF is typically hemoptysis, which may be recurrent or persistent. The diagnostic pathway for ABPF encompasses medical history, clinical evaluation, blood tests, sputum and blood cultures. Computed tomography angiograp
