Use of studded Polyflex stents in patients with neoplastic obstructions of the central airways.
The Polyflex is a commercially available silastic airway stent with proven efficacy. Due to a smooth outer surface its anchorage in the airway wall is superficial which may lead to stent migration. ⋯ The studded Polyflex showed excellent efficacy, was very well tolerated, and had a very low migration rate. It presents an improvement over the older smooth model and can be considered a true alternative to the most widely used silastic stent, the Dumon stent.
