Tracheobronchial strictures: treatment with a polyurethane-covered retrievable expandable nitinol stent--initial experience

Radiology. 1999 Dec;213(3):905-12. doi: 10.1148/radiology.213.3.r99dc02905.

Abstract

A polyurethane-covered retrievable expandable stent was placed in 13 patients with tracheobronchial strictures. In four patients with benign strictures, the stent was removed with use of a retrieval hook 2-6 months after placement. After stent removal, three of the four patients did not need further treatment. The retrievable stent warrants further investigation in the treatment of tracheobronchial strictures.
