There are many different kinds of brain hemorrhage depending on the site, but generally speaking, brain hemorrhage refers to bleeding in the brain parenchyma. The amount of cerebral hemorrhage and the site of hemorrhage determine the prognosis of cerebral hemorrhage. 1.Basal ganglia hemorrhage: Basal ganglia is the most common site of cerebral hemorrhage, and the ruptured hematoma of the doublestem artery is located in the basal ganglia. Basal ganglia hemorrhage can be subdivided into: shell nucleus hemorrhage, thalamic hemorrhage, caudate nucleus head hemorrhage, etc. The clinical manifestations are related to the site of hematoma and the amount of hematoma. The common symptoms in case of large amount of hemorrhage are hemiparesis caused by damage to the internal capsule, bilateral eye gaze to the side of the lesion, and hemianesthesia. When the hemorrhage is large, it affects the circulation of cerebrospinal fluid and compresses the brain tissue, resulting in coma, respiratory and heartbeat effects for a short time, and even death within a short time. The characteristics of thalamic hemorrhage are similar to those of thalamic hemorrhage, such as paraplegia and sensory impairment, but also mental disorders, such as depression and apathy, and dementia and memory loss, etc. A large amount of hemorrhage can be life-threatening for a short time. Due to the location near the third ventricle, symptoms of thalamic hemorrhage tend to recur, and symptoms such as persistent and persistent hyperthermia may also occur. (3) Hemorrhage in the caudate nucleus: it is rare, the bleeding volume is often small, and it mostly breaks into the ventricles, and acute hydrocephalus symptoms such as nausea, vomiting, headache, etc. usually do not appear typical symptoms of limb hemiparesis, and the clinical manifestations can be similar to those of subarachnoid hemorrhage. 2, lobar hemorrhage: the incidence is less, accounting for about 5% to 10% of cerebral hemorrhage, generally combined with intracranial vascular malformation, hematologic disease, smog disease and other patients are common, hematoma is common in one lobe, sometimes also accumulated two haunted lobes, clinically the parietal lobe is most common, because the location of the hemorrhage is more superficial, the hematoma is generally larger, according to different parts and the amount of bleeding, the clinical manifestations are more common and complex, can have limb Partiality, seizures, aphasia, headache, urinary incontinence, visual field loss, etc. 3, cerebral bridge hemorrhage: cerebral bridge hemorrhage accounts for about 10% of cerebral hemorrhage, the cerebral bridge is a more important life center, this type of hemorrhage is quite critical, greater than 5 ml of bleeding can appear coma, tetraplegia, respiratory distress and other symptoms, but also acute stress ulcers, central intractable hyperthermia, etc., most patients soon after the onset of multi-organ failure, often within 48 hours after the onset of The cerebral bridge hemorrhage is a kind of critical cerebral hemorrhage because it is extremely dangerous, and the treatment rate and cure rate are low. 4, cerebellar hemorrhage: the cerebellum is located in the posterior cranial fossa, bleeding greater than 10ml that there is a surgical pointer. Cerebellar hemorrhage accounts for about 10% of cerebral hemorrhage. After the onset, cerebellar function can be impaired: vertigo, ataxia, frequent vomiting, severe pain in the posterior occipital region, and generally no symptoms of hemiplegia of the limbs, and cerebellar hemorrhage can affect respiratory function when the cerebellar bridge is compressed. After hemorrhage in the cerebellar earth (the central part of bilateral cerebellar hemispheres), the hematoma may compress the four ventricles and affect the cerebrospinal fluid circulation, resulting in acute hydrocephalus within a short period of time, which requires surgery if necessary. 5, ventricular hemorrhage: primary ventricular hemorrhage is less common, but mostly seen in the peripheral parts of the hemorrhage broken into the ventricles. Primary ventricular hemorrhage symptoms are more obvious, such as sudden onset of headache, vomiting, neck tonicity, etc. A large amount of bleeding can quickly enter coma symptoms. According to the clinical manifestations after hemorrhage, neurosurgery clinically classifies cerebral hemorrhage into five grades as reference for surgical indications: Grade I: wakefulness or drowsiness with varying degrees of hemiparesis or aphasia; Grade II: drowsiness or haziness with varying degrees of hemiparesis or aphasia; Grade III: shallow coma with hemiparesis and equal pupil size; Grade IV: coma with hemiparesis, equal or unequal size; Grade V: deep coma, de-cerebral tonicity or tetraplegia, pupils unilaterally or bilaterally dilated
