To treat the sequelae of cerebral infarction is dizziness, the relevant drugs are betahistine, flunarizine hydrochloride and other such drugs. However, it is necessary to clarify the relevant vascular changes, and if no significant effect is seen after active medical conservative treatment, it is necessary to pay attention to the vascular lesions. If the vascular lesions are not relieved, no amount of medication will be effective. Therefore, a vascular examination should be performed to clarify whether there are large artery stenosis or occlusive changes. If there is a large artery stenosis, such as carotid stenosis or middle cerebral artery stenosis, it can lead to intractable dizziness, which can be treated surgically, such as stenting or endothelial debridement. For occlusions, such as carotid artery occlusion or middle cerebral artery occlusion, these can also be treated with superficial temporal artery and middle cerebral artery vascular anastomosis. These are indicated for dizziness that is refractory to oral medications and are very effective in reducing dizziness by opening up the blood vessels and allowing the brain to receive adequate blood supply.
