It was reported to boston scientific corp (bsc) on oct 7, 2009, that 6 polyflex airway stents were used during 6 esophageal stenting procedures performed on a male. According to the complainant, the pt had suffered from esophageal atresia since birth. The pt had undergone frequent repeated esophageal dilatations in hopes of removing his feeding tube. The attending physician was researching other options. She consulted with another physician regarding his temporary stenting technique. The physician was made aware by bsc that this was an off-indication technique. After throughly researching the use of stents, consulting with her team of surgeons, and receiving the consent of the pt's family, the physician decided to proceed with the treatment. Beginning in 2009, a series of 6 polyflex airway stents were placed consecutively in the pt's esophagus. Each of the first five stents were placed, left in place for approx 2 weeks, and then removed without issue. The treatment was successful with the pt able to progress to the oral intake of food. The physician stated that the first five stents were unrelated to the event. The final stent was placed the following month. The following month, the pt was admitted to the hosp emergency room with esophageal bleeding. It was discovered that the pt had a congenital malformation of blood vessels which had ruptured due to pressure of the stent. The stent was removed without issue and the bleeding was stopped. A few days later, the pt expired. According to the physician, the cause of death was the congenital malformation of blood vessels that ruptured due to pressure of the final stent. This condition was unk at the time of placement and was only discovered when the pt presented with esophageal bleeding. An autopsy was performed. Bsc requested autopsy results and was informed that results would not be released. Although the physician stated that the first five stents placed were unrelated to the event, without the definitive cause of death from the autopsy results, bsc has decided to conservatively file medwatch reports on all six stent complaints associated with this event. Bsc will continue to pursue further clarification of this event. If add'l info is obtained, a supplemental mdr will be submitted to the fda. This report is for the third stent placed.
