Whether or not to operate on double aortic arch should be determined by the doctor. Generally speaking, surgery is not necessary for the time being when there are no symptoms, but is recommended when there are obvious symptoms.
Double aortic arch is formed when the fourth pair of aortic arches fail to absorb and degenerate during embryonic development. One runs anteriorly from the trachea to the left side, and the other crosses the trachea and esophagus and mostly meets the left arch. Both aortic arches may be patent, or one may be partially patent or atretic.
In general, when the twin aortic arches are not compressing the trachea and esophagus, observation can be continued without surgery for the time being. When the double aortic arch compresses the trachea, dyspnea, coughing and recurrent respiratory infections may occur, and the compression of the esophagus may cause vomiting, difficulty in feeding, or even reflex apnea, and prompt medical attention should be sought, and the surgeon should determine the timing of surgery according to the specific situation.
