Cerebral hemorrhage in the traditional sense is the elderly “patent”, generally believed to be due to hypertension, cerebral arteriosclerosis resulting in cerebral vascular rupture bleeding caused by the pediatric why also suffer from cerebral hemorrhage? It turns out that the etiology of pediatric cerebral hemorrhage is different from that of adults, and it is generally believed that pediatric cerebral hemorrhage is mainly caused by the following three reasons: First, newborns in the process of delivery due to birth trauma or hypoxia, which can lead to intracranial vascular permeability increases, so that blood rushes into the brain tissue and causes cerebral hemorrhage. Second, infants due to vitamin K deficiency, affecting the synthesis of coagulation factors, resulting in bleeding or bleeding, if it occurs in the brain will cause cerebral hemorrhage. Third, cerebral hemorrhage caused by congenital cerebral aneurysm or other cerebral vascular malformations is mostly seen in older children and teenagers. Once cerebral hemorrhage occurs, it will seriously affect the physical health of children, which may cause different degrees of sequelae, or endanger their lives, so the key is how to prevent the occurrence of cerebral hemorrhage. First of all, newborns should avoid difficult or premature birth, and infants should replenish vitamin K in the pediatric body in time. As for cerebral aneurysm or other cerebral vascular malformations, which are mostly caused by congenital factors, the key to prevention lies in how to discover cerebrovascular lesions in time and take corresponding treatment measures to prevent cerebral vascular rupture and cerebral hemorrhage. Cerebral aneurysms or other cerebrovascular malformations often have no obvious symptoms, but if there are often unexplained dizziness or secondary epilepsy should be promptly examined in the hospital, and at present, MRI is a magnetically sensitive imaging technology that is sensitive and radiation-free to hidden cerebral vascular malformations and small hemorrhages that are difficult to be detected by conventional CT, MRI, and even angiography.
