Objective:
We aimed to explore the risk factors of seizure recurrence and the optimal surgical procedure for epileptic pediatric patients with moyamoya disease (MMD).
Methods:
We reviewed 696 consecutive patients with MMD admitted to our hospital from 2009 to 2015. Pediatric patients with MMD who had seizures before revascularization were identified. We summarized the characteristics of seizures in pediatric patients with MMD and analyzed the predictive factors of recurrent seizure events.
Results:
We identified 28 pediatric patients with MMD who had seizures before revascularization. During follow-up (median 42 months), 7 patients (25.0%) experienced recurrent seizures. In the multivariate analysis, the duration of epilepsy was an independent predictor for postoperative seizure recurrences (odds ratio 3.84, 95% confidence interval 1.54-24.34; P = .035). The 2 common surgical modalities of MMD (direct and indirect bypass) had no significant difference in future seizure prevention in pediatric patients with MMD with epilepsy.
Conclusions:
We identified the duration of epilepsy as an independent risk factor for recurrent seizure after revascularization in pediatric patients with MMD.
Insights
Epilepsy duration predicts seizure recurrence in pediatric moyamoya disease (MMD) patients after revascularization. Surgical bypass type did not significantly impact seizure prevention in these MMD cases.
Area of Science:
- Neurology
- Neurosurgery
- Pediatric Neurology
Background:
- Moyamoya disease (MMD) is a rare cerebrovascular disorder.
- Epilepsy is a common complication in pediatric MMD patients.
- Revascularization surgery is performed to prevent ischemic events.
Purpose of the Study:
- To identify risk factors for seizure recurrence in pediatric MMD patients.
- To evaluate the effectiveness of different surgical procedures for seizure control in pediatric MMD.
Main Methods:
- Retrospective review of 696 MMD patients (2009-2015).
- Identified 28 pediatric MMD patients with pre-operative seizures.
- Analyzed seizure characteristics and recurrence predictors.
Main Results:
- Seven out of 28 pediatric patients (25%) experienced recurrent seizures post-operatively.
- Longer epilepsy duration was an independent predictor of seizure recurrence (OR 3.84, P=.035).
- Direct and indirect bypass surgeries showed no significant difference in seizure prevention.
Conclusions:
- Epilepsy duration is a significant risk factor for post-revascularization seizure recurrence in pediatric MMD.
- Current surgical approaches for MMD do not differ in their efficacy for preventing seizures.
