Asphyxia secondary to airway obstruction has numerous underlying causes, both acute and chronic. Causes of chronic airway obstruction, such as neoplasms and tracheal scarring, are often clinically apparent well prior to asphyxia. Causes of acute airway obstruction may not be as obvious to clinicians or investigators. These include infections, anaphylactic reactions, status asthmaticus, inhalati...

BACKGROUND Airway obstruction or tracheoesophageal fistula (TEF) near the tracheal carina requires placement of Y-shaped stents. Herein, we describe our multicenter experience with the placement of Dumon silicone Y-stents. We also conduct a systematic review for studies describing the deployment of airway silicone Y-stents. METHODS This was a retrospective analysis of consecutive subjects who...

BACKGROUND Disturbed breathing during sleep, with episodic upper airway obstruction, is frequent after major surgery. Ventilatory responses to hypercapnia and hypoxia during episodes of airway obstruction are difficult to investigate because the usual measure, that of ventilation, has been attenuated by the obstruction. We simulated the blood gas stimulus associated with obstruction to allow in...

Atopic, obese asthmatics exhibit airway obstruction with variable degrees of eosinophilic airway inflammation. We previously reported that mice obese as a result of a genetic deficiency in either leptin (ob/ob mice) or the long isoform of the leptin receptor (db/db mice) exhibit enhanced airway obstruction in the presence of decreased numbers of bronchoalveolar lavage fluid (BALF) eosinophils c...

The laryngocele is an abnormal cystic dilatation of the saccule or appendix of the laryngeal ventricle, filled with air and communicating with the lumen of the larynx. When the neck of the laryngocele is obstructed, it becomes filled with mucus of the glandular secretion and is changed to a laryngomucocele. When this lesion becomes infected, a laryngopyocele is formed. The laryngocele is fairly...

Abstract Ascariasis is a common helminthic infection, particularly in the tropical countries. We describe case of eosinophilia who underwent coronary artery bypass graft (CABG) surgery. Postoperatively, he was found to have ascaris lumbricoides oral cavity. Timely detection and removal worm prevented possible complications such as airway obstruction, bronchospasm, lung collapse, or intestinal o...

PURPOSE The objective of this study was to evaluate external beam radiotherapy (EBRT) in lung cancer patients who suffer from airway obstruction. MATERIALS AND METHODS Medical data of 95 patients with a lung mass that obstructed the airway and received EBRT for it were analyzed. Fifty-nine patients (62.1%) had non-small cell lung cancer and 36 patients (37.9%) had small cell lung cancer. Radi...

Congenital high airway obstruction syndrome (CHAOS) is the obstruction of the fetal upper airways, which may be partial or complete. It is important to diagnose it antenatally as it is uniformly lethal and leads to stillbirth or death shortly after delivery. Antenatal diagnosis is made by identifying echogenic and enlarged lungs, dilated bronchi, inverted /flattened diaphragm and ascites on ult...

OBJECTIVE To evaluate the efficacy, safety, and outcome of prenatal imaging and fetal surgery in the diagnosis and management of fetal airway obstruction caused by cervical teratoma or lymphatic malformation. SETTING Tertiary care medical center. Patients A retrospective study of all consecutive fetal patients with cervical teratoma or lymphatic malformation between January 2001 and December ...
