Background And Purpose

Method

We searched our characteristics of seizures associated with brain arteriovenous malformations prospectively maintained AVM database at Beijing Tiantan Hospital and identified 198 pediatric patients with brain AVMs between the year 2009 and 2014. Seizure presentation, patient characteristics, AVM features, treatment modalities, and postoperative outcomes, especially post-treatment seizure control were collected. Univariate and multivariate logistic regression analyses were applied to determine the risk factors for seizure presentation as well as the predictors for seizure control.

Conclusion

In pediatric patients with brain AVMs, prior hemorrhage, larger AVM size, and frontal lobe location may predict subsequent seizures. Highest seizure control can be achieved by complete obliteration of the AVMs with microsurgical resection.

Main results

Before initiation of any treatments, 63 (31.8 %) of the overall 198 patients presented with seizure. According to multivariate analyses, larger AVM size, frontal AVM location, and history of prior hemorrhage were significantly associated with seizure presentation (all p < 0.05). For patients with pre-treatment seizure presentation, good seizure outcome was achieved in 73.8 %. AVM obliteration, short-period history of seizure, and short duration for seizure onset were independent predictors of good seizure outcome in the multivariate analysis. For the 135 patients without seizures at presentation, the overall rate of de novo seizures was 4.4 %.
