Abstract
BACKGROUND
Children with a congenital heart disease (CHD) are at a higher risk of developing epilepsy than the general population, but detailed characteristics of CHD-associated epilepsy have not been clarified. The purposes of this study were to determine the risk factors for developing epilepsy associated with CHD and to elucidate the characteristics of such epilepsy.
METHODS
We performed a retrospective cohort study based on medical records of pediatric patients with CHD who were born between January 2006 and December 2016, underwent cardiac surgery at Okayama University Hospital, and were followed up until at least age three years. Multivariate logistic regression analysis was used to determine factors particularly associated with epilepsy occurrence. In patients who developed epilepsy, clinical data on seizure characteristics were further investigated.
RESULTS
We collected data from 1024 patients, and 41 (4.0%) developed epilepsy. The presence of underlying disease (odds ratio [OR]: 2.413; 95% confidence interval [CI]: 1.150 to 4.883) and the Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery score category 2 (OR: 4.373; 95% CI: 1.090 to 29.150) and category 5 (OR: 10.385; 95% CI: 1.717 to 89.016) were significantly related to epilepsy occurrence. Of the 41 patients with epilepsy, 15 (including nine with hypoplastic left heart syndrome) had focal impaired awareness seizures specified as autonomic seizures with vomiting, which tends to escape detection.
CONCLUSIONS
We clarified the risk factors for developing epilepsy in children with CHD. We also found that autonomic seizure with vomiting is an important symptom in these children.
