Synkopen nach Belastung

Vascular airway compression syndromes have to be differentiated from bronchial asthma. We report the case of an 11-year-old girl who had been treated for bronchial asthma since childhood and presented with recurrent syncope after exercise. A double aortic ring caused severe tracheal stenosis with reflex ventilation depression and CO2 retention documented by spiroergometry. After transsection of the right dorsal arch the symptoms resolved and flow-volume charts and gas exchange were normal.
