Stent malposition

Song et al. (1996) treated three patients with esophagorespiratory fistulas with their own covered (potentially retrievable) self-expanding nitinol stent. All three fistulas were successfully sealed off by stent insertion. In one patient the stent was initially malpositioned with coverage of the right main stem bronchus, but this problem was successfully solved with repositioning. Two patients died after 2 and 3 weeks one patient was alive at 24 weeks with good respiratory status.
