Resumo

As próteses na via aérea têm a função de manter as estruturas tubulares abertas e estáveis. A sua colocação está indicada essencialmente na obstrução intrínseca ou compressão extrínseca da via aérea, fístulas ou traqueobroncomalacia.

Com este estudo pretendeu-se determinar a tolerabilidade a eficácia de próteses na via aérea nas situações em que a sua colocação era imprescindível.

Procedeu-se ao estudo retrospectivo dos processos clínicos de 23 doentes em que se tinha procedido à colocação de próteses traqueobrônquicas através de broncoscopia rígida, durante dois anos consecutivos (2006-2007), na Unidade Funcional de Técnicas de Diagnóstico e Terapêutica, tendo sido avaliadas a indicação, a eficácia, a tolerabilidade, as complicações e a localização exacta da sua inserção, tendo em conta a informação imagiológica fornecida por TC do tórax. Em todas as situações foram utilizadas próteses flexíveis de silicone tipo Dumon (Tracheobronxane®), sendo previamente avaliada, através de broncoscopia flexível, a necessidade de técnicas complementares, nomeadamente laserterapia e dilatação mecânica.

O estudo efectuado permitiu concluir que a inserção de próteses não apresentou complicações, demonstrando boa tolerabilidade, tendo em conta a maioria das situações, de natureza neoplásica em estádio avançado, apenas com indicação terapêutica paliativa.

Abstract

The function of airway stents is to keep the tubular structures open and stable. Their insertion is essentially indicated for intrinsic obstruction or extrinsic compression of the airway, fistulae or tracheobronchomalacia.

The aim of this study was to determine the tolerability and efficacy of airway stents in situations in which their insertion was vital.

A retrospective study of airway stent insertion with rigid bronchoscopy (23 patients) was carried out over a two year period (2006-2007) at the Diagnostic and Therapeutic Techniques Unit.

We assessed indication, efficacy, tolerability, complications and exact insertion based on chest CT imaging. In all situations Dumon flexible silicon stents (Tracheobronxane®) were used, with the need for complementary techniques such as laser therapy and mechanical dilation having been previously evaluated by flexible bronchoscopy.

The authors conclude that stent insertion has no complications and good tolerability in the majority of advanced stage oncological situations with indication for palliative management.
