Abstract: Recurrent cerebral infarction (RCI) is very common in clinical practice. Intracranial and extracranial vessels diseases closely associate with the recurrence of cerebral infarction. Hypertension, diabetes, high homocysteine, etc., result in vascular stenosis and more infarction recurrence by atherosclerosis and arterial plaque formation. Study of the etiology of RCI is important for the secondary prevention of cerebral infarction.
