Dans cette configuration anatomique, l'aorte descendante est positionnée trop antérieurement par rapport à la colonne vertébrale. Par conséquent, la partie médiane de la bronche souche gauche (L2) se retrouve coincée entre l'aorte descendante et l'artère pulmonaire, entraînant une compression postérieure et un rétrécissement de la bronche.

If the descending aorta is located too far anteriorly, the mid-portion of the left mainstem bronchus (L2) can be trapped between the descending aorta and pulmonary artery, resulting in narrowing the bronchus.
A descending aorta located anterior to the spine can cause posterior compression on the mid-portion of the left mainstem bronchus.
In our opinion, all patients need to be optimized using medical therapy prior to considering surgical correction if that is an option, at a minimum to control secretions and infections, as well as optimum nutrition and at least two weeks of adequate growth and positive nitrogen balance in order to tolerate the stress of surgery.
