Intravenous infusion is typically used to treat acute cerebrovascular diseases, such as treating acute ischemic stroke, with the aim of dissolving blood clots and restoring blood flow. The treatment has strict time windows (usually within 4.5 hours or 6 hours of onset). It should be noted that intravenous infusion cannot permanently "unclog" blood vessels or prevent the occurrence of stroke. Additionally, there are certain risks associated with intravenous infusion in the elderly, which may include infusion reactions, iatrogenic infections, vasculitis, allergies, and other complications.

To prevent stroke, it is recommended to have regular health check-ups to timely understand the condition of cerebral blood vessels, including whether plaques are increasing, whether stenosis is worsening, and whether there are any changes in brain structure.
