Stroke is caused by blockage or narrowing of blood vessels within the skull, leading to ischemic necrosis of brain tissue and a range of symptoms. Typically, patients with strokes are seen in neurology departments. Of course, the location of the stroke varies, and each patient's clinical presentation is different. If a stroke occurs, a cranial CT scan can provide a clear diagnosis. Clinically, treatment primarily involves dehydration, lowering intracranial pressure, brain protection, and nutritional support. If the patient has a large area of cerebral infarction and high intracranial pressure, they can be seen in neurosurgery, where procedures such as craniotomy decompression may be used to reduce intracranial pressure.
