Use of endotracheal silicone stents for relief of tracheobronchial obstruction

Clinical Experience With a New Removable Tracheobronchial Stent in the Management of Airway Complications After Lung Transplantation

“…Non-surgical options for the correction of airways complications include balloon dilatation, laser photocoagulation, electrocautery resection, cryoablation, and placement of silicone or expandable metallic stents. 3,7,11,[25][26][27][28][29][30][31] Endobronchial correction of an airway stricture by thermal ablation and balloon dilatation permits immediate relief of symptoms but is often associated with recurrence of stenosis, necessitating more definitive palliation with endobronchial stent placement.…”

“…[25][26][27]32,43 Gianturco stents (Cook Medical Inc, Bloomington, IN) are no longer used due to a high incidence of serious complications such as stent fractures, difficult removal, and fatal hemoptysis as a result of bronchovascular fistulas. 3,44,45 Orons et al 30 concluded that Palmaz stents (Johnson and Johnson, Warren, NJ) are a poor choice for large airway stenosis and bronchomalacia, given the high risk of mechanical failure due to compression or trauma of these stents which exhibit plastic, rather than elastic, properties.…”

“…16,24 Therapeutic options include balloon dilatation, laser débridement, electrocautery resection, cryoablation, or placement of silicone or expandable metallic tracheobronchial stents. 3,11,[25][26][27][28][29][30][31] Frequently used airway stents include the Dumon, Palmaz, Wallstent, and more recently, the Ultraflex stent. 32-38 Selfexpandable metallic stents offer reduced mucus plugging and reduced migration as well as a high internal/ external diameter ratio compared with silicone stents.…”

Endobronchial Management of Advanced Lung Cancer

“…The Hood stent is placed in the same manner as the Dumon stent. 36 The Rüsch-Y stent (Fig 3) is a silastic stent with stainless steel c-rings that artificially represent the cartilage. The posterior wall of the stent is made of a thinner silastic plastic to make it more functional, similar to the membranous trachea itself.…”

Development of a new insertion technique and a new device for the placement of bifurcated airway stents

“…Alternative insertion techniques without direct vision had been described by Westaby and Shepherd [5] and Gaer et al [4]. Instead of a bronchoscope they used rubber bougies placed into the main bronchi to guide the stent while they maneuvered it into position with a Magill forceps.…”
