Neurosurgery can also look at cerebral infarction, but most patients with cerebral infarction need to be examined and treated in neurology.1. If the patient has a serious cerebral infarction, such as a large cerebral infarction in the cerebral hemispheres, when the patient is at risk of brain herniation, he can do surgical craniotomy and decompression or partial brain tissue resection in neurosurgery. 2. If the patient has a larger cerebellar infarction will also affect the function of the brainstem and cause obstruction of cerebrospinal fluid circulation, surgery in neurosurgery is also required. For example, craniotomy and decompression of the posterior cranial fossa or direct excision of part of the infarcted cerebellum to relieve brainstem compression.3. If hydrocephalus is accompanied by ventricular drainage treatment, the patient also needs to be treated in neurosurgery.
