Review
Tracheobronchial injuries (TBI) are a heterogenous group of sometimes life-threatening traumas with different management approaches. Symptoms are mediastinal and subcutaneous emphysema, bloody secretions from the airway or haemoptysis in alert patients, and high air leakage along the cuff or increased ventilatory resistance may be signs for TBI in intubated patients. The necessity of immediate clinical evaluation, CT-scan and bronchoscopic evaluation are essential for prompt diagnosis and classification as well as experienced air way management and treatment, these patients are best managed from interdisciplinary teams including thoracic surgeons. While iatrogenic tracheal membrane laceration from intubation can be treated by lesion bridging with ventilation tube, stent application, open operative repair or endoluminal repair, intraoperative accidental cuts should be repaired by direct suture or with vital tissue coverage in case of local ischemia. The management of blunt or penetrating injury is sequential and needs immediate establishment and maintenance of a secure patent airway to provide adequate oxygenation. The next step is the treatment of life-threatening collateral injuries like major hemorrhage, cranial trauma or major organ damage arranged in the trauma team. The treatment of penetrating injuries to the airway need operative exploration in almost every case with minimal local dissection and debridement followed by direct repair. Muscle flap coverage is useful in case of combined esophageal injury. Damage of the tracheobronchial tree after blunt trauma must be repaired by direct suture or local tissue sparing resection and anastomosis. These lesions can be missed in the initial phase and may become prominent with scar tissue formation, stenosis and atelectasis in the later phases.

Hemoptysis is one of the most common reasons for seeking emergency care. Infections and malignancy are the leading causes of hemoptysis although caused by various other pulmonary and extrapulmonary conditions. Most causes are self-limiting and do not warrant any aggressive investigation. Endobronchial telangiectasia can rarely cause hemoptysis and is seen in patients with hemorrhagic hereditary telangiectasia or scleroderma. Isolated diffuse endobronchial telangiectasia is rare and is only reported in one case in literature. We present another case of diffuse endobronchial telangiectasia in a young adult who presented with recurrent hemoptysis. Computer tomography scan was normal, but bronchoscopy showed multiple endobronchial arteriovenous malformations in the entire tracheobronchial tree.

Review
Airway surgery is often indicated in the management of benign or malignant pathological processes of the tracheobronchial tree. The surgeon undertaking this type of work has, however, the responsibility of understanding the particular anatomy applicable to these structures and procedures as well as be able to correlate imaging, intraoperative findings and anatomy. These are important considerations if one wants to reduce operative morbidity and improve potential for better long-term results. This paper reviews the most important anatomic features of the tracheobronchial tree putting emphasis on those features that are important to surgeons performing surgical procedures on those organs.

Review
Hemoptysis is usually a symptom of cardiopulmonary disease and is generally not in itself associated with death. A blood loss into the tracheobronchial tree of 600 ml in 24 hours or at a rate that poses a threat to life is referred to as massive hemoptysis. Hypervascularity within the bronchial circulation, usually associated with diffuse inflammatory disease of the lung, is common in patients with massive hemoptysis. Management should be directed at maintenance of oxygenation and localization of the source of bleeding. Temporizing maneuvers such as iced saline lavage, intravenous administration of vasopressin, endobronchial tamponade and bronchial artery embolization will often stabilize the patient in preparation for definitive surgery. Such a sequential plan of management may result in a 50% reduction in the rate of death from massive hemoptysis, which is otherwise 50% to 100%.

Review
Broncho-pleural fistula (BPF) is an atypical communication between the tracheobronchial tree and the alveolar/pleural space, with prolonged air leak (PAL). BPF is frequent and related to significant morbidity, prolonged length of hospital stay, and mortality. Nevertheless, in about 10%, more than 5 days of an air leak is considered a PAL, accounted for significant morbidity. Endobronchial valve is a novel device for the PAL management with minimal morbidity if related to surgical repairs. While it is suggested that surgical treatment should be undertaken when possible, endobronchial valves should be recommended as a therapeutic choice in high-risk patients. Placement techniques remain operator and patient friendly and allow the procedure to be performed with relative ease. Prospectively conducted, randomised, controlled clinical trials are needed where valve treatment is compared with other bronchoscopic techniques, surgical procedures, or both.

Review
Recently, the significance of anthracosis in the tracheobronchial tree, lung parenchyma, and even non-respiratory organs has been postulated and discussed in association with other diseases, especially tuberculosis. We reviewed the current literature by using the following key words in Medline/PubMed, Embase, and Google Scholar databases: anthracosis, anthracofibrosis, anthracotic bronchitis, biomass fuels, and mixed-dust pneumoconiosis. The bibliographies of eligible papers were also reviewed for further relevant articles. A total of 37 studies were assessed. The content of these studies was then divided into specific categories. Considering the pathogenesis, along with histopathological, radiological, and bronchoscopic results regarding anthracotic lesions, we suggest these findings be defined as "ANTHRACOSIS SYNDROME". For the first time, we describe a syndrome involving black pigmentation, which was previously thought to involve only the tracheobronchial tree. Until recently, it was not considered to be a single syndrome with different sites of involvement.

Review
Anatomic resections with bronchial and/or vascular resections and reconstruction, so called sleeve resections were originally performed in patients with impaired cardio-pulmonary reserves. Nowadays, sleeve resections are established surgical procedures of first choice for tracheobronchial pathologies, whenever anatomically and oncologically feasible. Experienced thoracic surgeons have a broad surgical armentarium to avoid a pneumonectomy and the morbidity and mortality associated with it. Sleeve resections are associated with better outcomes in all aspects. Thus, sleeve resection is not an alternative for pneumonectomy and vice versa. In this review article we set out to provide a contemporary overview on this topic.

Review
Endobronchial tuberculosis (EBTB) is defined as tuberculous infection of the tracheobronchial tree. The exact pathogenesis is unclear, and it has a heterogenous clinical course. Its diagnosis requires the clinician to have a high index of suspicion based on clinical symptoms and radiological features. Computed tomography and bronchoscopy are useful tools in its evaluation. The goal of treatment is in the eradication of tuberculous bacilli with appropriate anti-tuberculous therapy. Use of corticosteroids is controversial for the prevention of tracheobronchial stenosis. Interventional bronchoscopy or surgical intervention is employed to restore airway patency once significant stenosis occurs.

Review
The aim of this study was to investigate the features of partial anomalous left pulmonary artery (PALPA) and differences between cases with posterior versus anterior a nomalous vessels in relation to the tracheobronchial tree. We hypothesized that statistical significance was dependent on the course of the anomalous vessel due to airway compression in the posterior type. This study included cases obtained from the literature ( = 33) and an institution teaching file ( = 2). Information collected: age, sex, medical history, additional anomalies, anomalous vessel course, and respiratory symptoms. Data were analyzed with independent samples -test and Fisher's exact test. PALPAs were more commonly anterior than posterior. Mean age: 5.3 years (SD = 12.4) for anterior and 6.8 years (SD = 18.5) for posterior ( = 0.77). Respiratory symptoms: 20% of anterior and 60% of posterior cases ( = 0.032). Tracheobronchial anomalies: 35% of anterior and 60% of posterior cases ( = 0.182). Non-cardiac and non-tracheobronchial anomalies: 30% of anterior and 47% of posterior cases ( = 0.511). Kabuki syndrome: 25% of anterior and 6.7% of posterior cases ( = 0.207). In conclusion, respiratory symptoms were the only significant difference between anterior and posterior PALPA types.
