Abstract:
Benign thyroid disorders such as goiter, especially retrosternal, can cause tracheostenosis by extrinsic tracheal compression, which is due to the lack of specific symptoms often misdiagnosed. Tracheomalatia develops as a result to long term tracheal compression and refers to weakness of the trachea characterized by softness of the tracheal cartilage arches and by loss of regular tracheal structure. Tracheomalatia is characterized by reduction of the endotracheal lumen and may affect the entire trachea or may be localized to one portion of it. We present the case of a 72-year old patient with distinct tracheostenosis and tracheomalatia, caused by long term pressure by the retrosternal goiter. We have been monitoring the patient for last 20 years after the second endotracheal stent had been placed. The first one was placed 34 years ago, in 1981. On both occasions granulation tissue and colonization of bacteria occurred. In the end the placed stents were rejected and migrated to the main carina. Despite the tracheal diameter narrower than 5 mm the patient has been living normally without the stent for 17 years, with the exception of no hard physical labor. He had a few short term antibiotic therapies and bronchial toilets during symptomatic deteriorations. Diagnosing retrosternal goiter and surgical treatment on time is of crucial importance in cases such as this one. Considering the complications caused by the stent, our opinion is that the majority of patients may require conservative treatment with closely monitoring during respiratory infections.

Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
