What Is Increased Intracranial Pressure?

Any increase in the cranial volume caused by a variety of pathogenic factors, and the cerebrospinal fluid pressure measured by lateral supine lumbar puncture exceeding 2 kPa is the increased intracranial pressure. If headache, vomiting, visual impairment and vision occur A series of clinical manifestations, such as nipple edema, is called hypertensive intracranial syndrome.

Elevated intracranial pressure

Where the cranial volume increases due to multiple pathogenic factors, the lateral position

Increased intracranial pressure

1. Congenital hydrocephalus is common in infants and young children, which may be related to cerebrospinal fluid secretion and absorption dysfunction. Obstructive hydrocephalus in infants and young children is found in congenital malformations, such as aqueductal developmental abnormalities in the midbrain, congenital delayed cerebral and subtonsal hernia deformities, fourth ventricular atresia, and hydrocephalus.

Acquired hydrocephalus

(1) Obstruction of interventricular foramen, third ventricle, midbrain aqueduct, fourth ventricle, median foramen, cerebellar bulbar cistern caused by various causes of obstructive hydrocephalus.

(2) The omentum is sticky due to various reasons of traffic hydrocephalus, hydrocephalus after traumatic or spontaneous subomentum hemorrhage and meningitis.

(3) Cerebrospinal fluid absorption disorders Various venous sinuses are compressed or blocked, auricular hydrocephalus, etc.

(4) Excessive secretion of cerebrospinal fluid, such as choroid plexus papilloma.

(5) Blood-brain barrier destruction The blood-brain barrier destruction caused by various reasons leads to increased leakage of interstitial fluid.

Elevated intracranial pressure

Also known as benign intracranial pressure syndrome. It can be caused by sinus obstruction, endocrine disorders, hematopathy, Vit A hyperemia, drug reactions and metabolic diseases.
