successful sealing of post-covid-19 bronchopleural fistula with computed tomography scan-guided percutaneous cyanoacrylate glue injection: a case series

Bronchopleural fistula (bpf), a sinus tract between the bronchial system and the pleural space, is associated with covid-19 and can lead to pneumothorax, which increases the mortality rate. due to the analytical status of covid-19 patients, sealing the bpf necessitates the least minimal invasive treatment. herein, we demonstrated a technique of sealing post-covid-19 bpf with direct injection of cyanoacrylate glue under the guidance of a computed tomography scan. following glue injection, the bpf was completely sealed in all four patients. in conclusion, in covid-19 patients with small and distal bpf, percutaneous glue injection is recommended for bpf closure.
