Bronchial stenosis is known to complicate endobronchial tuberculosis despite medical therapy. It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea-orthodeoxia syndrome in a young woman with acute atelectasis due to post-tuberculosis bronchial stricture. Imaging revealed complete middle and right lower lobe atelectasis with a partially aerated right upper lobe...

Lung isolation in thoracic surgery is a challenge, this is even more complex in the presence of unknown tracheal stenosis (TS). We report two cases of unknown TS and its airway management. TS appears most frequently after long term intubation close to the endotracheal tube cuff or in the stoma of tracheostomy that appears as a consequence of the granulation tissue after the surgical opening of the trachea. Clinical history, physical examination, difficult intubating predictors and imaging tests (CT scans) are crucial, however most of tracheal stenosis may be unnoticed and symptoms depend on the degree of obstruction...

Tracheobronchial anomalies are common in congenital heart disease (CHD), including tracheobronchial stenosis, tracheal bronchus, cardiac bronchus, and bronchial isomerism, which can cause varying degrees of respiratory illness. It is necessary to assess tracheobronchial anomalies and make a preoperative airway evaluation. Multi-slice computed tomography (MSCT) and cardiac magnetic resonance imaging (MRI) are the most effective noninvasive modalities for the diagnosis of CHD and the associated tracheobronchial anomalies...

A juvenile female striped dolphin Stenella coeruleoalba live stranded on 4 March 2016 at Alassio, western Ligurian Sea coast, Italy. The dolphin died shortly after stranding, and a complete postmortem examination was performed. Necropsy revealed severe tracheal occlusion and unilateral bronchial stenosis with luminal accumulation of abundant green-yellow mucous-gelatinous material. Histological features suggestive of tracheobronchial aspergillosis were observed. Cultures of lung tissue and tracheo-bronchial exudate isolated Aspergillus fumigatus, identified by a Microseq D2 LSUrDNA fungal sequencing kit...

Introduction: Anthracofibrosis is a lesser known clinical entity. Patients present with chronic symptoms of cough and breathlessness with a history of biofuel/wood fire smoke exposure. There are distinct computed tomography (CT) imaging features of anthracofibrosis that can differentiate it from more common conditions such as tuberculosis (TB) and bronchogenic carcinoma. Findings include multifocal noncontiguous stenosis of bronchial tree, calcified enlarged mediastinal or hilar nodes, and secondary lung parenchymal changes...

OBJECTIVES: The advantages of a bronchial sleeve resection are well established. A clear majority of reported cases are of upper lobe sleeve resection. Reimplantation of the upper lobe bronchus after a lower sleeve lobectomy or bilobectomy (the so-called Y-sleeve resection) is infrequent. Related technical peculiarities are the main issues. We present our experience and results in this setting. METHODS: Between 1989 and 2015, we performed 28 Y-sleeve resections of the left lower lobe (n = 18) or right middle and lower lobes (n = 10)...

Bronchial obstruction is infrequent in the child. The main cause is malacia or benign stenosis. Management alternatives range from conservative treatment to complex surgical and/or endoscopic techniques. Placement of a stent can play a key role in situations where there is no other therapeutic option. However, the ideal stent is not yet available. In the last few years, progress has been made in the development and characterization of novel biodegradable materials in order to overcome the drawbacks of traditional stents made of silicone or metal...

The use of unilateral pulmonary artery occlusion (UPAO) test for the preoperative evaluation of pneumonectomy was reported in adult patients. On the contrary, in infants, no strategies have yet been recommended to predict hemodynamics after pneumonectomy, nor has use of the UPAO test been reported. We describe the first case of infant with abnormal pulmonary circulation in whom successful pneumonectomy was performed after preoperative evaluation using UPAO test. Right pneumonectomy was planned for an 8-month-old girl, because of decreased right pulmonary function, high risk of pneumothorax, and impaired left lung expansion due to overexpansion caused by severe left bronchial stenosis and bronchomalacia...

Objective: To explore the diagnostic value of endobronchial ultrasonography with a guide sheath (EBUS-GS) for peripheral pulmonary ground glass opacity (GGO). Methods: The clinical data of 27 consecutive patients with 27 GGOs diagnosed by EBUS-GS between November 2014 to December 2015 in our Cancer Hospital were retrospectively analyzed. The average age of these 27 patients, including 9 males and 18 females, was 59±11 years. The median lesion size of the 27 GGOs was 2.9±1.2 cm, including 24 mixed GGOs and 3 pure GGOs...

Endobronchial Tuberculosis is hazardous in causing circumferential narrowing of tracheobronchial tree despite the eradication of tubercle bacilli in the initial insult from Pulmonary Tuberculosis. They may present as treatment resistant bronchial asthma and pose challenge to airway management in the acute setting. We present a 25 year-old lady who was newly diagnosed bronchial asthma with a past history of Pulmonary Tuberculosis that had completed treatment. She presented with sudden onset of difficulty breathing associated with noisy breathing for 3 days and hoarseness of voice for 6 months...

AIMS: Primary tracheal-bronchial adenoid cystic carcinoma (thoracic adenoid cystic carcinoma; TACC) is a rare and aggressive malignant tumour. Radiotherapy results have not been previously individualised in this setting. PATIENTS AND METHODS: Records of 31 patients with TACC (74% tracheal and 26% bronchial) who received radiotherapy between February 1984 and September 2014 were retrospectively analysed. RESULTS: Surgical removal of the primary tumour was carried out for most (71%) patients, and 13/22 (59%) had R1 or R2 (1/22) margins...

BACKGROUND: Tracheal and bronchial stenosis is a life-threatening condition causing difficulty in breathing and even severe respiratory distress. The silicone tracheobronchial stents were placed using the rigid bronchoscopy into the trachea of severe dyspneic patients and they exhibited symptomatic improvement as well as a rise in the saturation of oxygen. The bronchial stents were applicable to many extensive malignant airway stenosis patients, such as those with esophageal cancer, lung cancer, and laryngeal cancer...

Post-tuberculosis bronchostenosis (PTBS), a complication of endobronchial tuberculosis is currently treated by bronchial stenting. However, in cases of angulated bronchial stenoses, difficulty is often encountered in stent insertion and maintenance, resulting in stent migration, granulation tissue overgrowth, and restenosis. To accommodate the angulated alignment of the stenosis, we devised an "angulated stent"-a novel improvisation of the conventional stent via splicing and suturing to achieve a resultant angulated shape...

BACKGROUND: Airway stents are traditionally used in central airway obstructions to maintain airway patency. Historically, distal bronchial stenting within lobar and segmental bronchi has not been amenable to stenting. In addition, there are questionable benefits to stenting small airways. The Atrium iCast stent is a polytetrafluoroethylene covered stainless steel balloon deployed stent which can be deployed through a flexible bronchoscope under direct visualization. The purpose of this study was to assess the feasibility, complications, and long-term impact of using this stent in patients with lobar bronchial stenosis either secondary to malignancy or benign etiologies...

Tracheobronchopathia osteochondroplastica (TPO) is a rare pathology characterized by a progressive segmentary stenosis of the respiratory tract due to proliferation of osteocartilagineous nodules in the lumen of the distal part of the trachea and large bronchial trunks. Prognosis is usually benign, but some cases with an acute progression and a lethal outcome have been described. Clinical presentation is non specific, the chest x-ray is generally normal and there are not typical radiological signs of suspicion: diagnosis of TPO is usually incidental...

There is a dearth of data on management of anastomotic airway dehiscence following lung transplantation. Herein we report a case of successful conservative management of an anastomotic airway dehiscence after cadaveric donor lung transplantation. A 41-year-old woman with primary ciliary dyskinesia underwent cadaveric bilateral lung transplantation without cardiopulmonary bypass. On the postoperative day 25, left pneumothorax developed and bronchoscopy demonstrated a localized anastomotic dehiscence at the left main bronchus...

Tuberculosis (TB) is one of the leading causes of morbidity and mortality worldwide. Early diagnosis and treatment are key to prevent Mycobacterium tuberculosis transmission. Bronchoscopy can play a primary role in pulmonary TB diagnosis, particularly for suspected patients with scarce sputum or sputum smear negativity, and with endobronchial disease. Bronchoscopic needle aspiration techniques are accurate and safe means adopted to investigate hilar and mediastinal lymph nodes in cases of suspected TB lymphadenopathy...
