Treatment consists of surgical division; however, data regarding mid-term results are scarce. The purpose of this study was to evaluate clinical results of vascular ring surgery.<\/jats:p><\/jats:sec><jats:sec id=\"S1047951121004224_as2\"><jats:title>Methods:<\/jats:title><jats:p>Retrospective chart review of consecutive patients who underwent vascular ring surgery.

In total, 50% were symptomatic to some degree at their last documented clinic visit complaining of stridor (36.8%), cough (34.2%), wheezing (10.5%), dyspnoea on exertion (10.5%), or recurrent respiratory infections (23.7%). By telephone questionnaires, 83% described a significant improvement in respiratory symptoms, 63.4% had some residual symptoms, 36.6% stridor, 38.8% chronic cough, 32.4% bronchodilator use,18.3% had at least one episode of pneumonia per year, 31% of children had dyspnoea or respiratory limitation, and 12.7% while doing physical activities.

We found no association between the age at surgery or anatomic variant to the presence of symptoms at mid-term follow-up.
