Note: the date of event is unk. On april 25, 2007, a boston scientific corporation employee became aware of a clinical study article, "performance of a self-expanding silicone stent in palliation of benign airway conditions", published in chest (american college of chest physicians/chest 2006;130;1419-1423). The study conducted was a retrospective review of the medical records of all patients in whom a polyflex stent was used to treat a symptomatic benign airway condition. The following information was derived from that article. Case # 6 - record 2 of 2. Three days after a second polyflex stent placement in the trachea of a male patient, the "stent migrated". The stent was replaced with a unk t-tube. The patient was "doing well with t-tube. " "all patients with stent-related complications had increased shortness of breath and cough. " several attempts have been made to obtain the patient's current status to no avail. "a ct scan of the chest aided the selection of a stent with an appropriate diameter. Stents were oversized by 1 to 2 mm compared to the desired lumen; the latter was based on the proximal extent of the abnormality. The length of the stent was based on a direct measurement of the obstructed segment using a flexible bronchoscope. Depending on the degree and type of the stenosis, dilation of the involved airway was performed either using a rigid bronchoscope (rb) or a balloon prior to the stent placement. Endobronchial electrosurgery was used to cut concentric-type, web-like stenosis, if indicated. All stents were placed via an rb or a suspension laryngoscope under general anesthesia and fluoroscopic guidance using a team approach. "
