Insights
Endovascular thrombectomy (EVT) is a feasible and safe treatment for acute ischemic stroke (AIS) in children with large vessel occlusion, even when initiated after 6 hours. However, children with heart disease face a poorer prognosis.
Area of Science:
- Pediatric Neurology
- Interventional Neuroradiology
- Vascular Neurology
Context:
- Acute ischemic stroke (AIS) in children is a rare but serious condition.
- Endovascular thrombectomy (EVT) has emerged as a promising treatment for AIS in adults.
- The feasibility and safety of EVT in pediatric AIS require further investigation.
Purpose:
- To evaluate the feasibility and safety of EVT for treating AIS in pediatric patients.
- To assess the efficacy of EVT in achieving vascular recanalization and improving neurological outcomes.
- To identify potential complications and risk factors associated with EVT in children.
Summary:
- This retrospective study analyzed 4 pediatric AIS cases treated with EVT, achieving successful recanalization (mTICI≥2b) in all.
- Neurological deficits improved significantly post-EVT, with 3 out of 4 patients showing good recovery at 6 months.
- EVT was technically feasible and safe, with no perioperative complications; however, one patient with congenital heart disease experienced a fatal outcome.
Impact:
- EVT can be a viable treatment option for pediatric AIS caused by large vessel occlusion, even beyond the standard 6-hour window.
- The study highlights the importance of considering comorbidities, such as congenital heart disease, which may influence prognosis.
- Findings support the expanded use of EVT in pediatric stroke care, emphasizing the need for specialized centers and further research.
Abstract:
Objective: To assess the feasibility of endovascular thrombectomy (EVT) for the treatment of acute ischemic stroke (AIS) in children. Methods: Clinical data and follow-up information of 4 AIS children who received EVT in the Department of Intervention & Hemangioma at the Children's Hospital of the Capital Institute of Pediatrics from December 2020 to June 2021 were collected retrospectively. The vascular recanalization after EVT was assessed by the modified thrombolysis in cerebral infarction (mTICI) score. Efficacy outcomes were assessed with initial and postprocedural Pediatric National Institutes of Health Stroke Scale (PedNIHSS) score, and the modified Rankin scale (mRS) score at 3 and 6 months after treatment. Safety assessments included perioperative complications and intracranial hemorrhage post-treatment. Results: A total of 5 EVT treatment were performed on 4 children with AIS, of whom 3 were male. The age of onset was 4.6, 13.8, 7.8, 8.0, 8.9 years, respectively. The time from symptom onset to initiation of EVT was 19.0, 25.0, 22.0, 4.0, 16.5 hours, respectively and all patients achieved successful recanalization of the vessel after EVT (mTICI≥2b). The PedNIHSS score was 39, 14, 25, 39, 24 before treatment and decreased to 8, 1, 12, 39, 5 at discharge. All the procedures were performed with no perioperative complications. Only 1 patient with congenital heart disease had a recurrent AIS with malignant brain oedema and brain hernia. Although the occluded vessels were successfully recanalized,the symptoms were not improved and this patient died after treatment abandonment. The other 3 patients achieved good recovery at 6 months postoperatively. The mRS score of 3 patients was 3, 1, 2 at 3 months after EVT and decreased to 2, 1, 1 at 6 months. Conclusion: EVT treatment may be feasible and safe for pediatric AIS due to large vessel occlusion even when the treatment was initiated 6 hours post stroke, but children with heart disease may have a dismal prognosis.
