Cerebral infarction can be treated surgically. The following conditions are mainly applicable: 1. For large cerebral infarcts in the cerebral hemispheres, craniotomy and partial cerebral tissue resection can be performed. 2. For patients with larger cerebellar infarcts, especially those affecting brainstem function or causing obstruction of cerebrospinal fluid circulation, posterior cranial fossa craniotomy and direct resection of part of the infarcted cerebellum can be performed to release brainstem compression. 3. For patients with hydrocephalus or patients with hydrocephalus risk, ventricular drainage should be performed.4. If the patient has a large amount of secondary bleeding after cerebral infarction and the intracranial pressure is increased, the patient can also consider debulking decompression surgery for treatment if there are no contraindications.5. For patients with carotid stenosis over 70%, carotid endarterectomy and angioplasty can be considered for treatment.
