Abstract

Objective Our goal in this study is to assess the impact of congenital vascular ring (VR) on cognitive performance and its outcome after surgical correction.

Background The clinical indication for VR abnormalities relies on symptoms of tracheal and esophageal compression. However, the possible influence of VR on neurocognitive function and intelligence in school-aged children has yet to be examined.

Methods Patients with VR (n=78), which divided into two groups, partial (PVR) or complete vascular ring (CVR), and 30 normal controls were analyzed with Wechsler Intelligence Scale for Children-III (WISC-III) to assess the intellectual abilities before and one year after surgical intervention.

Results The initial assessment showed that the overall performances of the two VR groups on all the intelligence measurements are significantly lower than the control group. Nevertheless, the post-operational assessment of the VR groups one year later had shown significant improvement in most of the intelligence categories measured.

Conclusions The current results indicate a strong possibility of the influence of VR on neurocognitive development in school-aged children which is prompt to improve after surgical intervention is applied.
