Abstract . Several studies reported an association of congenital heart diseases (CHD) with hemodynamical involvement and/or chronic hypoxia, and abnormal electroencephalograms (EEGs), with the most common abnormalities being background activity immaturity, focal and multifocal paroxysms of sharp waves and spike/slow-wave complexes. In addition to its diagnostic value, the EEG started being used as a tool with prognostic value. The current study was conducted to detect possible cerebral ischemic EEG changes among pediatric patients with ventricular septal defect (VSD) after cardiac closure surgery. The study included 45 participants divided into group I (30 children with VSD after cardiac surgery) and group II (10 normal children as a control group). The current showed that the mean age of group I was 8.16±3.90 years, while in group II it was 11.13±1.88 years. The majority of cases had peri- membranous VSD (82.4%), 14.3% had doubly committed VSD and 7.1% had the muscular type, while 3.6% had multiple VSDs. The majority of cases (85.7%) underwent surgical patch technique, while 21.4% underwent primary closure. Delta and theta EEG power were significantly elevated in group I, while there was no statistically significant difference regarding alpha EEG power at the left and right occipital regions. Based on the results of the current study, further research is recommended to determine the true neurological meaning of the EEG findings after on-pump operations. In addition, correlative studies are required to assess the potential association between EEG changes with the cognitive function of children with VSD before and after cardiac surgery |
