RESUMO

A obstrução das vias aéreas centra is tem múltiplas etiologias. Estas obstruções põem problemas de dificil resolução para o broncoscopista dependendo das causas e localização da estenose, da sintomatologia e do grau de urgência.

A obstrução maligns das vias aéreas é a mais frequente (77,1% na nossa casuística) quer por invasão por tumor exofitico quer por compressão extrínseca tumoral/compressão por invasão linfática mediastínica (CNPCP-59 doentes; CPPC-1 doente; Tumores metastáticos-7 doentes; Tumores raros-4).

As estenoses benignas resultam habitualmente de entubação traumática ou são secundárias a ventilação prolongada. Na nossa casuístics, esta situação encontrou-se em 22,9% dos casos, devidos sobretudo a estenose traqueal pós entubação.

A nossa experiência inclui 70 tratamentos laser em 54 doentes, 38 tratamentos laser mais colocações de prótese em 30 doentes e 12 colocações de próteses em 8 doentes, de Junho/93 a Junho/95. 81,4% dos doentes eram homens e 19,6% mulheres, com idades compreendidas entre 18 e 78 anos.

As compticações foram poucas e podem considerar-se " típicas" destes procedimentos técnicos. A mortalidade global foi de 0,83% (1 doente).

ABSTRACT

Central airways obstruction has multiple etiologies. These obstructions put difficult problems to the bronchoscopist depending on the cause and localization of the stenosis, on the symptomatology and on the degree of emergency.

The most common lesion is malignant airway obstruction (77, 1% in our series) either by endoluminal exophytic tumor invasion or by extrinsic tumor/mediastinal limph node compression (NSCLC-59 patients; SCLC-1 patient; Metastatic lung tumors-7 patients; Rare pulmonary neoplasms-4 patients).

Benign stenosis usually results from intubation trauma or long term ventilation. In our series, a benign origin was present in 22,9% of the cases, mainly due to post entubation tracheal stenosis.

Our experience includes 70 laser treatments in 54 patients, 38 laser plus stent in 30 patients and 12 stent placements in 8 patients, from June/93 through June/95. 81,4% of the patients were men and 19,6% women, with ages ranging from 18 to 78 years.

Complications to date have been few and we consider them "typical" in such procedures. the overall mortality is 0,83% (1 patient).
