ABSTRACT

Cerebrovascular diseases attributed to coronavirus disease 2019 (COVID-19) are uncommon but can result in devastating outcomes. Pediatric acute ischemic strokes are themselves rare and with very few large vessel occlusion related acute ischemic strokes attributed to COVID-19 described in the literature as of date. COVID-19 pandemic has contributed to acute stroke care delays across the world and with pediatric endovascular therapy still in its infancy, it poses a great challenge in facilitating good outcomes in children presenting with acute ischemic strokes in the setting of COVID-19. We present a pediatric patient who underwent endovascular therapy for an internal carotid artery occlusion related acute ischemic stroke in the setting of active COVID-19 and had an excellent outcome thanks to a streamlined stroke pathway involving the vascular neurology, neuro-interventional, neurocritical care, and anesthesiology teams.

ABSTRACT

A rare case of a hypoplastic internal carotid artery (ICA) terminating in the ophthalmic artery with multiple intracranial saccular aneurysms in the contralateral ICA, anterior communicating artery fenestration and triple A2 was identified. The aetiology and pathogenesis of ICA hypoplasia are subjected to certain hypotheses. Developing several collaterals to preserve the blood supply of the ipsilateral cerebral hemisphere could result in aneurysm formation due to flow overload on the contralateral vasculature, but it could also result in hemicranial hypoplasia, cerebral atrophy and deep watershed infarcts, as in our case.

ABSTRACT

COVID-19 is well known for its respiratory symptoms, but severe presentations can alter haemostasis, causing acute end-organ damage with poor outcomes. Among its various neurological presentations, cerebrovascular events often present as small-vessel strokes. Although uncommon, in predisposed individuals, large-vessel occlusions (LVOs) can occur as a possible consequence of direct viral action (viral burden or antigenic structure) or virus-induced cytokine storm. Subtle presentations and complicated stroke care pathways continue to exist, delaying timely care. We present a unique case of COVID-19 LVO manifesting as an acute confusional state in an elderly man in April 2020. CT angiography revealed 'de novo' occlusions of the left internal carotid artery and proximal right vertebral artery, effectively blocking anterior and posterior circulations. Delirium can lead to inaccurate stroke scale assessments and prolong initiation of COVID-19 stroke care pathways. Future studies are needed to look into the temporal relationship between confusion and neurological manifestations.
