“…Since the first reported successful endobronchial management of BPF using tissue glue and a lead shot [19], many reports using different materials have been attempted. These include ethanol [20], silver nitrate [21], polyethylene glycol [22], cyanoacrylate compounds [23][24][25], coils [26,27], fibrin or tissue glue [28][29][30], doxycycline [31,32], albumin-glutaraldehyde tissue adhesive [33,34], cellulose [35], balloon catheter occlusion [36], calf bone [6], stents [6], gel foam [37], Watanabe spigots [38], endobronchial valves (EBV) [39][40][41], vascular devices and plugs [10,[42][43][44][45] pleurodesis (ABP) [46][47][48]. Each has their own inherent limitations and their reported success rates vary widely.…”
