Neurological Sequelae Following Pediatric Cardiac Interventions

Abstract

AIM: The aim of the present study was to assess neurological sequelae within 30 days of surgical or cardiac catheter interventions in infants and children. METHOD: In this cross-sectional study, we evaluated all patients who developed neurological problems after cardiac interventions either by surgery or by catheter by clinical evaluation, brain imaging, and electrophysiological studies. RESULTS: Among 1200 procedures were performed; 895 (74.6%) were cardiac catheterizations either diagnostic or intervention, 167 (13.9%) were open-heart surgery, and 138 (11.5%) were closed heart surgery. The overall incidence of post-procedure neurological dysfunction in the studied population was 3.4%. The differences between the three groups were statistically significant (p < 0.0001(. In our series, the neurological complications were in the form of disturbed conscious level in 2/41 (4.9%), impaired motor function in 11/41 (26.8%), impaired mental functions in 6/41(14.6%), hyperreflexia in 27/41 (65.9%), and seizures in 38/41 (92.7%). The most common presentation of seizures was in the form of focal fits 21/41 (51.2%), followed by generalized fits in 15/41(36.6%) and then myoclonic fits 2/41 (4.9%). CONCLUSION: Seizures are the most common complication following cardiac interventions in pediatric age and the highest percentage following open heart surgery.
