Innominate artery compression of trachea
ABSTRACT Innominate artery may cross the trachea and cause airway obstruction is a rare cause of vascular obstruction of airway. We describe a child with stridor, inability to extubate in whom the diagnosis was suspected on fluoroscopy and confirmed by angiography. Reimplantation of the innominate artery resulted in excellent results with longterm follow up. Variantions of this condition and modalities for confirmation of diagnosis are discussed.

ABSTRACT: Anomalies of the great vessels of the mediastinum are not uncommon, but only a small fraction of cases involving vascular compression of the airway cause obstructive symptomatology . Tracheal compression by the innominate artery is the most common of the compression syndromes caused by incomplete vascular rings and often causes mechanical upper airway obstruction in children  CT and MR imaging have been useful in delineating the vascular anatomy in multiple planes and have made angiography superfluous. Three-dimensional reconstruction at CT and MR imaging can provide images of even greater detail before surgery
