Study Highlights:
- New Information: This study demonstrates the effectiveness of endovascular electroencephalography (eEEG) in detecting lateralized epileptic discharges in animal models, suggesting its potential clinical utility.
- Importance: eEEG could offer a less invasive and more accurate alternative to traditional EEG for monitoring brain activity, particularly in epilepsy.
- Contribution to Literature: The study provides evidence supporting the use of eEEG for lateralization detection in epilepsy, which has not been widely adopted clinically despite its introduction in the 1990s.
Results Summary:
The study involved three pigs with induced epileptogenicity in different hemispheres. eEEG electrodes were inserted into the transverse sinuses, and their readings were compared with subdural electrodes (SDs). The results showed a significant alignment between eEEG and SDs (p < 0.001). The sensitivity and positive predictive values (PPV) for detecting lateralization were high: F00001 (0.93 sensitivity, 0.96 PPV), F00002 (0.99 sensitivity, 1.00 PPV), and F00003 (0.98 sensitivity, 0.99 PPV). Neurological physicians were able to determine the correct side of epileptogenicity using eEEG alone, except for one physician who got all sides incorrect. No abnormalities or vascular damage were observed upon post-experimental dissection.
