How is neonatal brain edema caused?

summary

How is neonatal brain edema caused? Neonatal brain edema is a kind of brain disease, which is caused by the increase of water content in the brain and the increase of brain volume. It is the reaction of brain tissue to various pathogenic factors. It is generally caused by congenital factors, dystocia and asphyxia, acute infection, food and drug poisoning.

How is neonatal brain edema caused?

Neonatal brain edema is actually a kind of brain disease with increased water content in the brain, which leads to increased brain volume. It is the reaction of brain tissue to various pathogenic factors. It is generally caused by congenital factors, dystocia and asphyxia, acute infection, food and drug poisoning and other factors. Neonatal brain edema generally leads to intracranial hypertension and damages brain tissue. Clinically, it is common in nervous system diseases, such as craniocerebral trauma, intracranial infection (encephalitis, meningitis, etc.), cerebrovascular diseases, intracranial space occupying diseases (such as tumors), seizures and systemic diseases, such as toxic dysentery and severe pneumonia.

Brain injury. All kinds of brain injury, directly or indirectly caused by brain contusion and laceration, can cause brain edema, complicated with intracranial hematoma, so that local brain tissue compression can also cause brain edema. The depressed fracture of skull may cause compression on the brain tissue, or the fracture piece may be directly injured by penetrating into the brain tissue, resulting in brain edema at the affected part, blast injury, gas wave impacting the chest, or the chest may be directly squeezed, resulting in a sharp increase in the pressure of the superior vena cava, which spreads to the brain and impacts the brain tissue, causing extensive diffuse punctate hemorrhage of capillaries in the brain tissue, Capillary permeability increased, often diffuse brain edema, diffuse axonal injury of the brain, can be secondary to severe diffuse brain edema.

Intracranial space occupying lesions. The tumor makes the brain tissue around the tumor compressed or blocked, cerebral venous return, increased venous pressure, intracranial congestion, absorption disorder of cerebrospinal fluid circulation machine, and tumor biological toxicity, etc., which affect the brain tissue around the tumor, damage or destroy the blood-brain barrier, increase the permeability of vascular wall, and produce localized brain edema. Brain edema is particularly significant in primary malignant tumors of the brain. Brain metastases of lung cancer and choriocarcinoma, whether single or multiple, have serious brain edema around the lesions.

matters needing attention

The so-called brain edema refers to the pathological phenomenon of brain water increase and brain volume increase, which is the response of brain tissue to various pathogenic factors. Brain edema can cause intracranial hypertension and damage brain tissue. According to the pathomorphology and pathogenesis of brain edema, it can be divided into four categories, each of which has different damage to the brain. Therefore, early detection and early treatment are advocated.
