Methods: All patients who had a hospital discharge with a IDC-9-CM code 7503 tracheoesophageal fistula and esophageal atresia), between January 2008 and June 2016 entered the present study. [frontiersin.org]

If severe, it presents very early on in life with airway obstruction requiring immediate surgical intervention. [patient.info]

Clinical presentation Individuals with laryngeal lymphangioma may be asymptomatic or may present with significant airway obstruction when the lesions attain a large size. [emedicine.medscape.com]

Obviously, if the original obstruction is severe, the child will present early and with more severe symptoms, including presentation of stridor in the delivery room (SUMMARY) (SUMMARY). [virtualpediatrichospital.org]

• Collapse

  As a result, the airways collapse and become inflamed, resulting in the deposition of a glassy, proteinaceous film, or "hyaline membrane" on the alveolar surface that impedes gas exchange. [web.duke.edu]

  There was a collapsing lumen opening into a non-collapsible structure i.e. esophagus (collapsible) with absence of proximal trachea continuing with distal trachea (non-collapsible) [Figure 1]. [jiaps.com]

  Tracheobronchomalacia - Tracheobronchomalacia is an uncommon condition in which the trachea collapses on itself during breathing and with coughing. [verywell.com]

  Because the trachea collapses during cough, secretions in the lungs aren’t expelled efficiently during respiratory infections, increasing the risk of bronchitis or pneumonia (a lung infection). [we-are-eat.org]

  In very experienced surgery centers, tracheal resection and reconstruction (anastomosis complete end-to-end with or without laryngotracheal temporary stent to prevent airway collapse) is currently the best alternative to completely cure the stenosis and [en.wikipedia.org]

  Tracheostomy - A tracheostomy is a surgical procedure in which an endotracheal.tube is inserted directly into the trachea. [verywell.com]

  Many unanswered questions still remain in surgical and clinical arenas. [dovepress.com]

• Aspiration

  Food (especially liquids) can travel through this gap into the respiratory tract, resulting in aspiration. [we-are-eat.org]

  Feeding difficulties and aspiration may also occur. [emedicine.medscape.com]

  Foreign body aspiration is a common cause of acute stridor. The peak incidence is between one and two years of age. The foreign body is usually food. A history of aspiration or choking can be obtained in 90 percent of cases. [aafp.org]

  In the mildest situation, in everyone who previously had a TEF, whenever they cough, this membranous portion vibrates like a clarinet reed, giving a very loud, vibratory, brassy, or “honking” cough. [we-are-eat.org]

  The most common symptoms of laryngotracheal foreign bodies are cough, stridor and dyspnea, whereas those of bronchial foreign bodies are cough, decreased breath sounds, wheezing and dysphagia. [aafp.org]

• Respiratory Distress

  Respiratory distress and cyanosis are rare. [emedicine.medscape.com]

  Baby continued to have respiratory distress with copious oral secretions. Baby was intubated and shifted to NICU for mechanical ventilation. [jiaps.com]

  Neonates with laryngeal atresia usually presents at birth with severe respiratory distress, central cyanosis, strong respiratory effort, and an inability to have an audible cry. [omicsonline.org]

  Respiratory distress, failure to thrive and cyanosis are rare. Oxygen saturation should be monitored. [patient.info]

• Dyspnea

  […] airway may be necessary. esophageal atresia congenital lack of continuity of the esophagus, commonly accompanied by tracheoesophageal fistula, and characterized by accumulations of mucus in the nasopharynx, gagging, vomiting when fed, cyanosis, and dyspnea [medical-dictionary.thefreedictionary.com]

  Presentation [ edit ] The most common symptom of laryngotracheal stenosis is gradually-worsening breathlessness ( dyspnea ) particularly when undertaking physical activities (exertional dyspnea). [en.wikipedia.org]

  The most common symptoms of laryngotracheal foreign bodies are cough, stridor and dyspnea, whereas those of bronchial foreign bodies are cough, decreased breath sounds, wheezing and dysphagia. [aafp.org]

  The child may also present with dyspnea, a brassy or barky cough, hoarseness, and/or weak or unusual cry. A prolonged episode or unusual course of croup may also bring the child to attention. [virtualpediatrichospital.org]

  Laryngoceles typically cause intermittent symptoms including hoarseness and dyspnea made worse by crying (Fig. 6.7 ). Vallecular cysts often cause early onset of stridor associated with cough and cyanotic episodes (Fig. 6.8 ). [entokey.com]

These doctors, members of the Cincinnati Children’s Aerodigestive Center, will discuss their findings and treatment plan with you. Early treatment focuses on getting the infant ready for surgery to repair the airway. [cincinnatichildrens.org]

One of these procedures is called a fetal EXIT (ex utero intrapartum treatment) procedure. This surgery is done in the operating room by fetal surgeons from CHOP's Center for Fetal Diagnosis and Treatment. [chop.edu]
