Aims/Objectives They contain two lesions: anomaly and stenosis. They may associate with other congenital lesions especially pulmonary artery sling. Tracheal stenosis is the main factor causing airway obstruction. Depend on the degree of tracheal stenosis, clinical manifestation ranges from having some episodes of stridor to severe respiratory failure and death. Reconstruction surgery is the met...

INTRODUCTION Wegener's granulomatosis (WG) is a form of systemic vasculitis that involves primarily the upper and lower airways and the kidneys. The most frequent airway manifestations include subglottic stenosis and inflammation, and tracheal and bronchial stenoses. The endoscopic visualization of the airways is the best tool for assessing, diagnosing and managing those changes. OBJECTIVES T...

OBJECTIVES Vascular endothelial growth factor A (VEGF-A) is important in the angiogenic response for wound healing. This study investigated whether VEGF-A may play a role in the pathogenesis of acquired airway stenosis. METHODS Eight lesions from 5 pediatric patients with subglottic stenosis after airway reconstruction (N = 4) or prolonged intubation (N = 1) and normal laryngeal tissue from 5...

Bronchoscopic balloon dilation (BBD) is a useful method of treating tracheobronchial stenosis. Tracheobronchial stenosis in adults can arise from benign or malignant disease. Benign stenosis causes include sarcoidosis, tuberculosis, Wegener’s granulomatosis, trauma, berylliosis, and foreign body reaction. Furthermore, it can arise after prolonged endotracheal intubation, after sleeve resection ...

Tracheal stenosis has numerous possible etiologies, including iatrogenic trauma from an over-inflated endotracheal/tracheostomy tube cuff, malignancy, chronic inflammatory diseases (eg, sarcoidosis), and various collagen vascular diseases (eg, Wegener disease, relapsing polychondritis). If an underlying etiology cannot be identified, the condition is termed idiopathic tracheal stenosis. First r...

Unanticipated difficult airway is a challenging problem for anesthesiologists. Oropharyngeal stenosis (OPS) is a rare complication of upper airway surgery which may cause difficult airway. We present a patient whose postsurgical OPS was revealed during the induction of general anesthesia, and necessitated reschedule of surgery and tracheotomy. We also discuss the etiology and risk factors of po...
