• Collapse

  collapse (dynamic airway collapse) or pathologic collapse (EDAC) ( 1, 2 ). [jtd.amegroups.com]

  RESULTS: Tracheal collapsibility varied widely among patients. Some had profound tracheal narrowing during quiet breathing, and others showed substantial collapse only during forced exhalation. [ncbi.nlm.nih.gov]

• Surgical Procedure

  Hence, a surgical procedure could be considered as an alternative to stenting in such cases. [ncbi.nlm.nih.gov]

  A person may be considered a candidate for this procedure depending on results of a short-term trial of stenting. Resection and reconstruction - this is a surgical procedure that may be used when TBD is more confined (focal). [rarediseases.info.nih.gov]

• Recurrent Infection

  Twenty-two percent of respondents never considered TBM in patients with cough, sputum production, dyspnea, and recurrent infections. Thirty-eight percent did not proceed with further evaluation of TBM if pulmonary function tests were normal. [ncbi.nlm.nih.gov]

• Falling

  It is also possible to have complications that affect the function of the trach tube, such as the tube slipping or falling out of place, or that affect the windpipe or other airway structures. [nhlbi.nih.gov]

  The biphasic flow-volume loop morphology is also characterized by a low maximum forced expiratory flow, which is followed by a rapid fall in flow, resulting in a plateau of very low flow for the remainder of exhalation. [rc.rcjournal.com]

• Dyspnea

  Improvement of dyspnea is the most consistent metric of treatment effect, likely because dyspnea is the most common presenting complaint in patients with diffuse TBM and because of the immediate effect of the stent on expiratory airflow. [jtd.amegroups.com]

  Thirty-three patients (94%) presented with severe dyspnea, 26 patients (74%) with uncontrollable cough, and 18 patients (51%) reported recurrent pulmonary infections. [ncbi.nlm.nih.gov]

  Case Report A76-year-old female was admitted to our hospital with complaints of cough, dyspnea, night sweats, and weight loss. She reported cough and progressive dyspnea for the preceding 10 years. [karger.com]

• Pneumonia

  TBM results in chronic cough, poor mucous clearance, and recurrent pneumonias. Apparent life-threatening events or recurrent pneumonias may require surgery. [ncbi.nlm.nih.gov]

  The most common complication was pneumonia (2/9, 22.2%) Median length of hospital stay was 7.5 days and no patients died postoperatively. [meetings.westernthoracic.org]

  The usual symptom of tracheomalacia is inspiratory stridor or laryngeal crow. Tracheomalacia may be congenital or acquired. [jpalliativecare.com]

  The subsequent clinical course was complicated by recurrent stridor, upper airway obstruction, and periods of profound oxygen desaturation. [fn.bmj.com]

• Pulmonary Disorder

  Also, the majority of previous studies review TBM in patients with multiple pulmonary disorders. There is marked variability in the incidence of TBM in the literature. [ispub.com]

• Failure to Thrive

  However, intervention may be needed in children with episodes of airway obstruction, frequent infections, respiratory failure, and/or failure to thrive. [rarediseases.info.nih.gov]

• Irritability

  In adults TBM is more often seen in smokers with chronic irritation of the airway, particularly middle aged or older men with COPD. [theasthmacenter.org]

  […] causes: Damage to the windpipe during a tracheostomy, where an incision is made into the windpipe and a tube is inserted to help with breathing Tracheal fractures Tumors pressing on the windpipe Thyroid tumors Dilated aortic or pulmonary arteries Chronic irritation [cedars-sinai.edu]

  Some masks can cause irritation. Your doctor can help you find ways to relieve these symptoms and adjust to using your CPAP machine. [nhlbi.nih.gov]

  However, risk factors for TBM include tracheal fractures, tracheostomy, tumors, and chronic irritation from conditions such as asthma, coughing and/or second hand smoke. [curetbm.org]

In this report, we review the treatment of TBM, including preoperative workup, intraoperative anesthesia management, and surgical technique for posterior splinting tracheobronchoplasty. [ncbi.nlm.nih.gov]

With increased awareness of TBM as an independent cause of clinical symptoms and functional impairment, the need for a standard diagnostic workup becomes more important. [rc.rcjournal.com]

As part of their diagnostic workup, all infants had structurally normal hearts on echocardiogram, normal sweat tests, and normal immune function. Gastro-oesophageal reflux was excluded or treated if confirmed. [fn.bmj.com]

Pulmonary function testing is often unhelpful in screening patients during the initial diagnostic workup. [jtd.amegroups.com]
