Brachycephal légúti obstrukciós szindróma I. Kóroktan, kórfejlődés és kórjelzés

Abstract

SUMMARY Brachycephalic airway obstruction syndrome, BAOS, is a frequent and character istic respiratory disease affecting brachycephalic breeds. In the present paper the authors review the complex aetiology of BAOS, which consists of congenital primary anatomical deformations due to forced breeding selection processes (stenotic nares, elongated and thick soft palate, macroglossia, abnormal naso pharyngeal turbinates and tracheal hypoplasia) and consecutive secondary changes (aedematous infiltration of laryngeal and pharyngeal areas, laryngeal collapse, tonsillar enlargement). The authors describe different deformations by anatomical regions. Following a short review of the gastrointestinal lesions that often accompany the specific respiratory condition associated with BAOS the authors give a full description of the possible diagnostic methods. Regard ing the progressive nature of the disease and the limitations of conservative therapy, early and complex surgical correction of the operable lesions is strongly advised in these patients.
