Self-expandable prostheses in the tracheobronchial tree.

Abstract: Under endoscopic and radiologic control, two types of self-expandable metal prostheses were implanted in tracheobronchial lesions to help reestablish airway caliber. Thirty-nine metal stent prostheses (6-20 mm in diameter) and 35 Gianturco stents (30 mm in diameter) were used in 55 adult patients with 62 lesions of the trachea (n = 33) or bronchi (n = 29). All lesions except one were endoscopically confirmed to be noninflammatory. Immediately after implantation, radiologic and endoscopic studies verified reest… Show more

“…Stents are inserted under sedation or anaesthesia, following previous dilatation or laser ablation of the stenosis under uoroscopic and endoscopic control. Two types of endobronchial stents are currently available in the tracheobronchial tree: silicone stents (Dumon, Dynamic, Reynders, and others) [181±183, 186,188,190] and metallic stents, the latter including either balloon expandable stents (Palmaz and Strecker) or selfexpanding stents (Gianturco, Wallstent, Ultra¯ex) [181,182,187,190,192,193,197,198]. Most metallic stents are available in covered and noncovered versions.…”

“…Os expansores metálicos, ao contrário das órteses de silicone, devido à presença de fenestrações, não interferem com a função ciliar e permitem o crescimento de novo epitélio respiratório, podendo ser colocados, além da usual aplicação traqueal, nos brônquios lobares sem haver bloqueio dos seus orifícios segmentares, mas não previnem o crescimento de tecido inflamatório ou neoplásico para o interior da órtese (23) . O manejo usual do crescimento tumoral na luz do expansor baseia-se na utilização de radiação endoluminal, laser, broncoscópio rígido e pinças de biópsia com resultados satisfatórios sem necessidade de troca pela órtese recoberta (21)(22)(23)(24) .…”

Entretanto, sendo indicada a colocação de uma órtese com cobertura, esta pode ser de teflon, dacron, silicone ou poliuretano, sendo especialmente útil no tratamento de fístulas esofágicas e para cavidade torá-cica associada a luz normal de via aérea, estando contraindicada a órtese de Dumon, segundo Bolliger et al (25) , como também em casos de estenose neoplásica com luz irregular da via aérea, conforme Cavaliere et al (26) .…”

“…Consequently, several companies started to develop other airway stents with silicone and metal. In the last 20 years, numerous reports have been published about the use of selfexpanding and balloon expandable metal stents for the treatment of tracheobronchial malignant and benign stenoses, tracheobronchomalacia (TBM), fistulas and dehiscences [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”
