Medical and Early Developmental Outcomes for Patients with Congenital Ventriculomegaly.

INTRODUCTION

This study evaluated whether comorbidities such as genetic conditions, other congenital anomalies, infection, and other exposures impact the mortality rate and/or neurologic outcomes of patients with congenital ventriculomegaly.

METHODS

This was a retrospective cohort study that assessed the mortality rate and developmental delay of 91 patients diagnosed with congenital ventriculomegaly followed at Cincinnati Children's Hospital Medical Center between January 1, 2010, and December 31, 2020.

RESULTS

Of the 91 patients included in the study, 20 (22.0%) had a genetic diagnosis. The mortality rate was higher for patients with a genetic diagnosis compared to those without a genetic diagnosis (p = 0.022), as was the rate of developmental delay (p = 0.026). The presence of comorbidities (confirmed genetic condition, confirmed maternal exposures or infections, and/or additional anomalies) was not associated with an increased risk of mortality nor developmental delay.

CONCLUSIONS

Patients diagnosed with congenital ventriculomegaly and a genetic condition have a significantly higher risk of early mortality and developmental delay compared to those without a genetic diagnosis. Therefore, diagnostic genetic testing should be considered after identification of congenital ventriculomegaly to facilitate counseling about prognosis and care management.
