چکیده

Wegener's granulomatosis (WG) is a disease caused by necrotising vasculitis of small and middle blood vessels of upper and lower respiratory tract and kidneys of unknown etiology. ENT symptoms develop in more than 90% of patients and tracheobronchial involvement occurs in about 20% of patients, most often as a subglottic stenosis. Subglottic stenosis occurs usually as a late complication of disease, but sometimes it may be an early isolated symptom. It is usually irregular, no longer than 2-4 cm and affects mucosa and submucosa but sometimes also cartilage. The diagnosis is based on clinical symptoms, X-ray of the chest, urine analysis, c-ANCA detection and histological examination of the granulation from the stenosis. The main treatment of subglottic stenosis in WG is a causal immunosuppressive treatment, however an equally important is a preservation of respiratory tract passage, because a dominant symptom in this form of WG is problem with breathing or even dyspnoea. In this publication basing on literature review different methods of treatment of laryngotracheal stenosis and its importance in WG are described and discussed. In literature presently less invasive operations are recommended. The treatment of choice is endoscopic treatment with repeated dilatations and injections of steroid into the stenosis. In big stenosis in immunologically active disease patient sometimes requires tracheotomy and after remission of disease and maturation of the subglottic scar laryngotracheal resection can be considered.

Subglottic stenosis in Wegener's granulomatosis: development during cyclophosphamide treatment with response to carbon dioxide laser therapy.

A patient with Wegener's granulomatosis rapidly developed a circumferential subglottic stenosis while on a cyclophosphamide regimen that had caused resolution of systemic symptoms and pulmonary infiltrates. The stenosis developed in the area of previously noted tracheal ulceration and responded satisfactorily to carbon dioxide laser therapy.

PURPOSE Wegener's granulomatosis (WG) is a rare multisystem inflammatory disease, which infrequently involves the subglottic area and trachea. Treatment usually involves the use of immunosuppressive agents with corticosteroids. Some patients, however, continue to have symptoms of airway obstruction after clinical remission following the standard therapeutic regimen. OBJECTIVE To investigate l...

Laryngeal and tracheobronchial involvement in Wegener's granulomatosis.

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...
