[Classification of childhood arterial ischemic stroke].

ABSTRACT

The etiology of childhood arterial ischemic stroke is complex, and identifying the underlying cause is crucial for optimizing treatment and preventing recurrence. Currently, the classification methods for childhood arterial ischemic stroke are largely based on data from international studies, but a unified consensus have not yet been reached. This paper reviews the existing classification methods and their subtype definitions, and points out some doubts and ambiguities. On this basisi, combined with the data collected by Beijing Children's Hospital on Chinese children with arterial ischemic stroke, a new classification method (COIST) was proposed according to the etiology and pathogenesis, namely inflammation (I), abnormal vascular structure (S), thrombophilia (T), heart disease (C), other identifiable causes (O), and uncertain causes; and various subtypes are listed. It is hoped that this new classification method can attract the attention and discussion of domestic colleagues, with the aim of further refinement, in order to help clinicians better understand and quickly identify the etiologies of childhood ischemic stroke.
