title: [Lateral tracheal indentation or compression by the brachiocephalic arterial trunk in children].
abstract: Three cases of compression of the right wall of the trachea by buckling of the innominate artery in childhood are described. A coarctation of the thoracic aorta is associated in two cases, and a left cervical aortic arch in the third one. In one case, a severe tracheomalacia occurs following the surgical repair of the associated coarctation. This lateral indentation of the trachea is suggestive of right aortic arch but the absence of posterior oesophageal indentation excludes the diagnosis. Angiography is helpful and echography is unable to demonstrate the vascular origin of the tracheal compression. The authors analyse the correct diagnostic approach, emphasize the risk of tracheomalacia and the high rate of associated cardio-vascular malformations.
