Tracheal Stenosis by Innominate Artery Compression in Infants: Surgical Treatment in 35 Cases

Tracheal compression by aberrant innominate artery: clinical presentations in infants and children, indications for surgical correction by aortopexy, and short- and long-term outcome

“…This finding agrees with the data previously reported by other authors in similar patient populations, that is, that a reduction of the tracheal lumen exceeding 70% can be indicated as a cutoff for surgical treatment of AIA-induced TC [24,25]. It is rationally acceptable that a severe tracheal obstruction can be not only associated with, but also pathogenetically linked to the presence of severe respiratory symptoms not responding to "standard medical treatments."…”

Mild tracheal compression by aberrant innominate artery and chronic dry cough in children

“…Other anatomic anomalies, such as primary tracheomalacia, can be important causative factors of this condition . However, as shown by the present study and by other reports, this syndrome may be detected also in older children, a later diagnosis being related to less severe symptoms and, possibly, to a lower degree of TC . How can a mild TC be involved in the pathogenesis of cough?…”

“…[5][6][7][8]10,27,31 However, as shown by the present study and by other reports, 8,24,[29][30][31][32][33] this syndrome may be detected also in older children, a later diagnosis being related to less severe symptoms and, possibly, to a lower degree of TC. 3,8,29,34 How can a mild TC be involved in the pathogenesis of cough? Firstly, in a significant proportion of children with mild compression on CT scans, the degree of tracheal narrowing in expiration or following cough was significantly greater during bronchoscopy due to concomitant tracheomalacia.…”

Innominate artery compression of trachea

“…More authors reported abnormal origin and course of the innominate artery as a cause of airway compression, with relief of symptoms following decompressive surgery. [2][3][4] However, others have disputed the role of the innominate artery in causing symptoms in these children, and believe that intrinsic abnormality of the trachea rather than compression by the innominate artery is responsible for the symptoms. 5 Strife et al reported that the innominate artery crosses anterior to the trachea, and produces mild to moderate anterior indentation of trachea in 30% of normal children without causing symptoms.…”
