However, we did eliminate TB and malignancy as the cause of her VFP because (1) she had no history of TB exposure, (2) her PPD was 8 mm, (3) her chest radiograph had no indication of TB, (4) acid-fast bacillus was not observed in the bronchial and gastric lavage and in her tracheobronchial
biopsy, and (5) no malignancy and/or TB was found.
It extends the endoscopist's vision to allow evaluation of the tracheobronchial
wall and parabronchial anatomy.
First, the value for height (h) does not appreciably change because the flow through the tracheobronchial
tree originates from the pressure gradient between the mouth and the alveoli.
It is considered to be less traumatic than rigid bronchoscopy and can be particularly useful for retrieving FBs lodged more distally in the tracheobronchial
Secretolytic activity was determined in mice by the secretion of intraperitoneally injected phenol red into the tracheobronchial
tract over a period of 30 min.
Lesions in the lungs, observed in 3 animals, were consistently found in combination with lesions in the tracheobronchial
and mediastinal lymph nodes; lesions in the tonsils were found with lesions in the retropharyngeal lymph nodes (Table 2).
9) Involvement of the tracheobronchial
tree, although rare, is the most common manifestation of thoracic amyloidosis.
For instance, respiratory tract specimens come from a broad range of fluids such as sputum, tracheobronchial
aspirate, and bronchoalveolar lavage as well as pleural puncture.
However, bleeding continued from endotracheal tube and bronchoscopy revealed alveolar hemorrhage with normal tracheobronchial
One patient (Patient 12; Figure 2) had stenting with Ultraflex[TM] Tracheobronchial
Stent System (Boston Scientific, Boston, MA, USA) stents via a flexible bronchoscope under moderate sedation in the ICU.
Tracheal bronchus, also referred to as bronchus suis or pig's bronchus, is a rare tracheobronchial
anomaly in which an ectopic bronchus arises from the lateral wall of the trachea above the carina and supplies the entire upper lobe or a segment of the upper lobe.
Pulmonary sequestration was first described by Rektorzik in 1861, as a nonfunctioning mass of lung tissue which lacks normal communication with the tracheobronchial
tree and with an anomalous systemic arterial supply.
