The management of tracheobronchomalacia is a very challenging problem with few treatment options. This study aims to evaluate the outcomes of a novel surgical treatment for membranous tracheobronchomalacia. A consecutive series of patients with tracheobronchomalacia were treated with two to three holmium laser scarring surgeries of the hyperdynamic tracheal and bronchial walls for the purpose of stiffening them through fibrosis. Patients filled out a Dyspnea Index questionnaire before and after treatment. Ten patients were treated for their tracheobronchomalacia with a mean age of 54 years...

The club cell secretory protein (CCSP) is a regulator of lung inflammation following acute respiratory infection or lung injury. Recently, the relationship between CCSP and COPD has been reported. Since COPD results from an abnormal inflammatory response, we hypothesized that CCSP could have a protective role against chronic inflammation-induced lung damage. To address this issue, the pathophysiology of chronic lung inflammation induced by Pseudomonas aeruginosa in CCSP-deficient mice was determined. A tube of 5 mm in length was soaked in a fluid containing P...

The case subject was a 58-year-old woman who presented to our hospital with a chief complaint of respiratory discomfort. Wheezing could be heard in both lungs; treatment was initiated with inhaled steroids for suspected bronchial asthma. However, 1 week later, the respiratory discomfort had not improved and the wheezing sound had progressed to the neck area. Upper airway obstruction was suspected; therefore, chest computed tomography (CT) was performed, revealing tracheal stenosis caused by a tumor in the upper airway...

Tracheobronchial amyloidosis is a rare presentation and accounts for about 1% of benign tumors in this area. The diagnosis of disease is delayed due to nonspecific pulmonary symptoms. Therapeutic approaches are required to control progressive pulmonary symptoms for most of the patients. Herein, we report a case of a 68-year-old man admitted with progressive dyspnea to our institution for further evaluation and management. He was initially diagnosed with and underwent management for bronchial asthma for two years but had persistent symptoms despite optimal medical therapy...

BACKGROUND: Wheezing is a common symptom in early childhood. However, refractory wheezing is difficult to treat, and it may thus account for extensive use of medical resources. It is therefore important to improve our understanding of the pathophysiology of refractory childhood wheezing. METHODS: In this descriptive study, we studied 156 children with refractory wheezing using fiberoptic bronchoscopy and bronchoalveolar lavage (BAL), and compared the results with a control group of 46 children with various pulmonary diseases but no wheezing...

A neonate with severe neonatal asphyxia was treated with therapeutic hypothermia. He developed hypothermia-induced respiratory deterioration, after which congenital tracheal stenosis and pulmonary artery sling were diagnosed. Even low-grade hypothermia is likely to induce bronchial narrowing in neonates, especially in neonates with congenital respiratory tract anomalies. Congenital tracheal stenosis represents a potential pitfall in differential diagnosis and should be carefully ruled out in cases of bronchial narrowing episode induced by therapeutic hypothermia...

Right-sided interrupted aortic arch (IAA) is a rare cardiac anomaly. In general, the right bronchus sits higher than the left bronchus, so aortic arch reconstruction with a direct anastomosis has a risk of tracheal and bronchial obstruction. This report describes the successful definitive repair of a right-sided IAA in a 2.5-kg neonate by aortic arch reconstruction with a pulmonary autograft tube (PA tube). Postoperative three-dimensional multidetector computed tomography showed the reconstructed aortic arch without airway obstruction or aortic stenosis...

Spirometry flow-volume measurement is used routinely in the outpatient setting to rule out obstructive lung diseases. Biphasic flow-volume loop is a classic presentation of unilateral bronchial stenosis due to multiple etiologies and it should raise clinical suspicion. Granulomatosis with polyangiitis (GPA) is a systemic inflammatory condition with pulmonary manifestations that may be infiltrative (e.g., pneumonia), hemorrhagic, and may rarely cause bronchial stenosis. Herein, we present a case of GPA-related, bronchial obstruction that caused biphasic flow-volume loop along with a literature review...

The use of bronchial stapling with automatic stapling devices has become widespread in chest surgery with the growth of video-assisted thoracoscopic surgery. Thus, hand suturing for the bronchus occurs less commonly. Therefore, modern surgeons have fewer opportunities to perform hand suturing, and, as a consequence, there exists lack understanding of this technique compared to earlier generations. We, therefore, examined the difference in bronchial patency between the Sweet and modified Overfolt methods of suturing performed on sacrificed pigs, as shown by bronchoscopy...

When the arterial switch operation includes the Lecompte maneuver, the arterial trunks are reconnected in parallel, rather than the spiral fashion observed in the normal heart. Thus, although the ventriculo-arterial connections are hemodynamically corrected, the anatomic arrangement cannot be considered normal. We hypothesized that, if feasible, it would be advantageous to restore a spiral configuration for the arterial trunks. In 58 patients, we reconstructed the arterial trunks such that, postoperatively, the pulmonary channel spirals round the aorta, passing to either the right or the left, and branches posteriorly...

Tracheobronchopathia osteochondroplastica (TO) is a relatively rare and benign disease of unknown etiology that is characterized by the accumulation of diffuse cartilaginous and osseous nodules protruding into the anterolateral walls of the trachea and bronchus. However, TO is easy to ignore or misdiagnose due to its nonspecific clinical manifestation. A chest computed tomography (CT) scan with a fiber bronchoscope and pathological biopsy shows the clinical features supporting the ultimate diagnosis.Here, we report 2 misdiagnosed cases of TO and review the literature to further define the diagnosis for clinicians...

BACKGROUND: Hemoptysis is a common complication in all kinds of surgery. However, it is rarely critical because it resolves with or without intervention. CASE PRESENTATION: Here the authors present what is believed to be an unprecedented report of a case involving a fatal idiopathic bronchial hemorrhage complication during cardiac surgery. Eighty-five-year-old female with severe aorticvalve stenosis had elective aortic valve replacement. Subsequently, she developed diffuse bilateral severe idiopathic bronchial hemorrhage which required maximum intervention such as external bronchial ligation, V-A ECMO, coil embolization of bronchial artery and internal airway blockage by spigot...

Acquired coronary diseases include aneurysms, fistulae, dissections, and stenosis. Aneurysms may occur secondarily to Kawasaki disease, a childhood vasculitis, the prognosis of which depends on the coronary involvement, or they may be degenerative, infectious, inflammatory, or traumatic in origin. Fistulae develop between the coronary arterial system and a pulmonary or bronchial artery, or cardiac cavity. Dissections may occur spontaneously or may be post-traumatic. These coronary abnormalities may be found incidentally or may present as complications, infarction or rupture...
