АРТЕРИАЛЬНЫЙ ИШЕМИЧЕСКИЙ ИНСУЛЬТ РАННЕГО ВОЗРАСТА, АССОЦИРОВАННЫЙ С МИНЕРАЛИЗУЮЩЕЙ ЛЕНТИКУЛОСТРИАРНОЙ АНГИОПАТИЕЙ И ЛЕГКОЙ ЧЕРЕПНО-МОЗГОВОЙ ТРАВМОЙ

Abstract

Study aims: 1) to evaluate the significance of mineralizing angiopathy of lenticulostriate arteries (MALA) in the development of arterial ischemic stroke (AIS) in children; 2) to study clinical and neuroimaging signs of AIS that develops after a head injury and does not meet the criteria of known disease types. Material and methods: to achieve the first aim, groups were formed: 1) the main group – patients with AI, n=86, Me 2,9 years; control – healthy children, n=131, Me 3,2 years. In the compared groups, neurosonography (NSG) protocols were studied for MALA. For the second aim, anamnesis and data from a clinical neuroimaging examination of 106 patients with AIS (Me 2,9 years) were analyzed. Stroke type was identified by the Childhood Arterial Ischemic Stroke Standardized Classification and Diagnostic Evaluation (CASCADE). Results: MALA increases the risk of AIS (ОR 16,15 [95% CI 5,43–48,1]). Stroke that does not meet the criteria of 1–5 types according to CASCADE is often associated with MALA. Clinical of AIS in patients with MALA are early age and mild head trauma (F=6,9, R=0,73, p<0,0001); the onset is marked by the absence of fever, vomiting, seizures, Glasgow coma scale 13, improvement in the first week (F=8,49, R=0,546, p<0,0001). Neuroimaging signs are the basal ganglia lacunar infarct and the absence of cerebral arteriopathy according to magnetic resonance angiography (F=52,8, R=0,402, p<0,0001). The percentage of this type stroke in children with AIS is 26,4%. Conclusion: MALA is a risk factor of AIS in children. AIS in infants which is associated with mineralizing angiopathy of lenticulostriate arteries and mild head trauma is an independent type of stroke. For its verification, computed tomography or NSG are needed.
