Insights
Diagnoses for pediatric focal cerebral arteriopathy varied significantly, with many patients experiencing changes in diagnosis and some suffering recurrent strokes. Further research is needed for better diagnostic criteria and treatment strategies.
Area of Science:
- Neurology
- Pediatric Stroke
- Cerebral Arteriopathy
Background:
- Focal cerebral arteriopathy (FCA) involves unilateral intracranial arteriopathy affecting the distal internal carotid artery and proximal middle and anterior cerebral arteries.
- Understanding the disease course in pediatric patients is crucial for effective management.
Observation:
- A retrospective review of 10 pediatric arterial ischemic stroke patients with FCA was conducted.
- Patients were treated at a single quaternary-care center between 2005 and 2014.
- Angiography and clinical data were reviewed by specialists.
Findings:
- Initial diagnoses included arterial dissection, moyamoya disease, embolic occlusion, hemorrhagic stroke, and vasculitis.
- At follow-up, diagnoses evolved, with transient cerebral arteriopathy, arterial dissection, and moyamoya disease becoming more prevalent.
- Four children experienced recurrent strokes.
- Treatments ranged from aspirin and heparin to tissue plasminogen activator and surgical revascularization.
Implications:
- There is significant variability in diagnosis, prognosis, and treatment for pediatric FCA patients with similar angiographic findings.
- Improved consensus-based diagnostic criteria are necessary.
- Further research is needed to identify disease biomarkers and predictors of arterial progression in pediatric focal cerebral arteriopathy.
Objective:
Focal cerebral arteriopathy is a term used to describe unilateral intracranial arteriopathy involving the distal internal carotid artery and proximal segments of the middle and anterior cerebral artery. We describe the disease course of 10 pediatric arterial ischemic stroke patients with focal cerebral arteriopathy from a single quaternary-care center.
Methods:
We retrospectively reviewed pediatric stroke patients with focal cerebral arteriopathy without lenticulostriate collaterals treated at our institution between 2005 and 2014. Angiography was reviewed by a child neurologist and a pediatric neuroradiologist, and chart reviews were performed.
Results:
Ten individuals with focal cerebral arteriopathy were identified. At the time of stroke presentation, four patients were diagnosed with arterial dissection, two with moyamoya disease, one with embolic occlusion, one with hemorrhagic stroke, and two with arterial dissection or vasculitis. At last follow-up, six patients had a change in diagnosis: four were diagnosed with transient cerebral arteriopathy, two with arterial dissection, and four with moyamoya disease. Four children experienced stroke recurrence. All were administered aspirin, one was administered heparin, two were administered intravenous tissue plasminogen activator, and five underwent surgical revascularization.
Conclusions:
Among pediatric stroke patients with a similar angiographic appearance, there is variable concordance between diagnosis, prognosis and treatment choice. Improved consensus-based diagnostic criteria and further research is needed to identify disease biomarkers and predictors of arterial progression.
