Tracheobronchomalacia is an uncommon acquired disorder of the central airways. Common symptoms include dyspnea, constant coughing, inability to raise secretions and recurrent respiratory infections. Evaluation includes an inspiratory-expiratory chest computed tomography (dynamic CT), an awake functional bronchoscopy and pulmonary function studies. Patients with significant associated symptoms and severe collapse on CT and bronchoscopy are offered membraneous wall plication. Tracheobronchoplasty is performed through a right thoracotomy...

Campomelic dysplasia is a rare skeletal dysplasia characterized by Pierre-Robin sequence, craniofacial dysmorphism, shortening and angulation of long bones, tracheobronchomalacia, and occasionally sex reversal. The disease is due to mutations in SOX9 or chromosomal rearrangements involving the long arm of chromosome 17 harboring the SOX9 locus. SOX9, a transcription factor, is indispensible in establishing and maintaining neural stem cells in the CNS. We present a patient with angulation of long bones and external female genitalia on prenatal ultrasound who was subsequently found to harbor the chromosomal abnormality 46, XY, t(6;17) (p21...

Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is a rare autosomal recessive disease characterized by infancy-onset diaphragmatic palsy and symmetrical distal muscular weakness. SMARD1 is caused by loss-of-function mutations in IGHMBP2 gene. In this article, we report a male SMARD1 patient with two compound heterozygous mutations (NM_002180.2: c.688C > G; p.(Gln230Glu)) and (NM_002180.2: c.1737C > A; p.(Phe579Leu)), one of which (c.688C > G; ClinVar accession: SUB3344743: SCV000612189) is novel...

Posterior descending aortopexy can relieve posterior intrusion of the left mainstem bronchus that may limit the effectiveness of posterior tracheobronchopexy. We review outcomes of patients undergoing both descending aortopexy and posterior tracheopexy for severe tracheobronchomalacia with posterior intrusion and left mainstem compression to determine if there were resolution of clinical symptoms and bronchoscopic evidence of improvement in airway collapse. All patients who underwent both descending aortopexy and posterior tracheopexy from October 2012 to October 2016 were retrospectively reviewed...

Tracheobronchomalacia (TBM) is characterized by weakness of cartilaginous supporting structures of tracheal and bronchial walls, resulting in central airway obstruction. It is a rare condition that can occur after prolonged intubation. Here, we report a 26-year-old, alcoholic male who had TBM, mild subglottic, and severe tracheal stenosis following 2 weeks of intubation. Subglottic and tracheal stenosis can occur after extubation but TBM is uncommon. The exact mechanism is still unknown but post-intubation TBM is a life-threatening condition with high morbidity and mortality if left untreated...

RATIONALE: Airway stabilization for severe, symptomatic tracheobronchomalacia (TBM) may be accomplished by silicone Y-stent placement. Common complications of the Y-stent include mucus plugging and granulation tissue formation. PATIENT CONCERNS: We describe a rare case of massive hemoptysis originating from a silicone Y-stent placed for TBM. DIAGNOSES: An emergent bronchoscopy showed an actively bleeding, pulsatile vessel at the distal end of the left bronchial limb of the Y-stent...

Tracheobronchomalacia (TBM) and excessive dynamic airway collapse (EDAC) are more frequently being recognized as the etiology of multiple types of respiratory complaints from chronic cough to exertional syncope to recurrent infections. Identification of these conditions requires a high suspicion, as well as a thorough history and physical examination. Dynamic computed tomography imaging and bronchoscopic evaluation are integral in achieving an accurate diagnosis. Once recognized, treatment ranges from addressing underlying contributing conditions to surgical stabilization of the airway...

Tracheobronchomalacia (TBM) is a common congenital disorder in which the cartilaginous rings of the trachea are weakened or missing. Despite the high prevalence and clinical issues associated with TBM, the etiology is largely unknown. Our previous studies demonstrated that Wntless (Wls) and its associated Wnt pathways are critical for patterning of the upper airways. Deletion of Wls in respiratory endoderm caused TBM and ectopic trachealis muscle. To understand mechanisms by which Wls mediates tracheal patterning, we performed RNA sequencing in prechondrogenic tracheal tissue of Wlsf/f ;ShhCre/wt embryos...

An infant with pulmonary atresia/ventricular septal defect/major aortopulmonary collateral arteries underwent unifocalization, ventriculoseptal defect closure and placement of a right ventricle to pulmonary artery conduit via median sternotomy. Aortopexy and pulmonary arteriopexy via redo sternotomy were insufficient to allow weaning of continuous positive airway pressure and he required direct tracheobronchopexy via left lateral thoracotomy to alleviate posterior trachealis intrusion along the length of the trachea and left main bronchus...

Tracheobronchomalacia is a rare but clinically troublesome condition in paediatrics. The softening of the major airways - which can include some or all of the tracheobronchial tree can lead to symptoms ranging from the minor (harsh barking cough, recurrent chest infections) to severe respiratory difficulties including prolonged ventilator support and 'near death attacks'. The causes are broadly divided into intrinsic softening of the airway wall which is considered a primary defect (e.g. syndromes; post tracheo-oesophageal fistula repair; extreme prematurity) or secondary malacia due to external compression from vascular structures or cardiac components...

BACKGROUND: Tracheobronchomalacia, defined as variable collapse of the airways, has been recognized as an important cause of respiratory morbidity but still widely underdiagnosed. Bronchoscopy is still considered as the gold standard, but numerous limitations are known, especially for fragile sick children. Moreover, information on parenchymal lung disease cannot be described. There is a real need for a reliable, non-invasive test to help detection of airway and parenchymal malformations in children, specifically when bronchoscopy cannot be performed...

Tracheomalacia patients often present with nonspecific symptoms like cough, wheezing and dyspnea. Tracheomalacia diagnosis is usually attributed to alternative common conditions such as asthma or chronic obstructive lung disease. Certain maneuvers, like forced expiration, or recumbent position may elicit subtle signs of tracheomalacia. Ordering novel pulmonary function testing in sitting upright and supine positions may provide additional clues to suspect tracheomalacia, which can be confirmed by either dynamic chest tomography or bronchoscopy...

Relapsing polychondritis (RP) is a rare systemic autoimmune disease that affects cartilaginous structures. RP causes tracheobronchomalacia (TBM) by affecting the bronchial cartilage. TBM is a fatal condition characterized by excessive weakening of the walls of the trachea and bronchi. We herein report a case of a 73-year-old man who experienced sudden respiratory failure due to TBM caused by RP. Immunosuppressive treatment did not improve his respiratory failure. Multiple metallic stentings dramatically improved his severe airway symptoms...

BACKGROUND Pulmonary embolism is a common acute postoperative complication and is associated with 100,000 deaths per year in the USA. Tracheobronchomalacia is an uncommon condition, which presents with similar symptoms to pulmonary embolism, including hypoxemia, tachycardia, and shortness of breath. We describe a case of a patient who presented with postoperative pulmonary symptoms that were initially thought to be due to pulmonary embolism. However, following imaging investigations these symptoms were found to be due to tracheobronchomalacia...

AIM: Persistent or recurrent wheezing is a common indication for flexible bronchoscopy, as anatomic and infectious or inflammatory changes are highly prevalent. We sought to evaluate the prevalence of anatomic, infectious, and inflammatory disease in a cohort of children undergoing flexible bronchoscopy for wheezing or poorly controlled asthma. METHODS: We retrospectively reviewed all children <18 years old who underwent flexible bronchoscopy at our center from October 29, 2012-December 31, 2016 for the primary or secondary indication of wheezing (persistent, frequently recurring, or atypical) or poorly controlled asthma...
