Hydrocephalus is a kind of what?

Hydrocephalus is a result of cerebrospinal fluid circulation obstacles, Too much or secretion of cerebrospinal fluid caused by poor absorption capacity increase, the increased intracranial pressure a disease. The disease may, at any age, but the majority occurred in after birth six months. Clinical to abnormal brain growth and increased speed, the knocking was "broken pots" The Sound Head beads droop like "Sunset-shaped" intelligence and insufficient as the main clinical manifestations. The medical classified according to their clinical manifestation "of the skull", areas. The physiological role of cerebrospinal fluid Intraventricular brain fluid mainly by the choroid plexus and capillary produce, produce 400 to 500 mL per day, about the maintenance of brain tissue and pressure constant osmotic pressure of the role, followed by brain tissue metabolism also plays the role of lymph, and a buffer of foreign forces, reducing shocks protection. CSF physiological cycle Choroid plexus and cerebrospinal fluid from the capillaries around a hole between the ventricles Room entered the third ventricle - the fourth ventricle - subarachnoid - superior sagittal sinus, some infiltration within the vertebral venous plexus. Hydrocephalus the clinical classification The vast majority of hydrocephalus is caused by cerebrospinal fluid circulation obstacles, so clinical classification based on the cerebrospinal fluid circulation obstacles site is divided into two types. Obstacles occurred in the fourth ventricle hole above, known as obstructive hydrocephalus, if the obstacles occurred in the fourth ventricle called on the transport of the following (current) nature of hydrocephalus. The reasons for the circulation of cerebrospinal fluid barrier (1) congenital malformation: more see is spina bifida, cerebral aqueduct malformations or cerebral vascular malformation, etc.. (2) Infection: If purulent meningitis or tuberculous meningitis failed early appropriate treatment, the proliferation of fibrous tissue obstruction of cerebrospinal fluid circulation channels, in particular the fourth ventricle hole at the bottom of the subarachnoid space and the brain adhesion. (3) Bleeding: intracranial hemorrhage after the fiber hyperplasia can cause hydrocephalus. (4) tumors: intracranial tumor obstruction of cerebrospinal fluid can be part of the cycle, was particularly prevalent in the vicinity of the fourth ventricle. (5) vitamin A deficiency may also increase the capacity of cerebrospinal fluid, resulting in the symptoms of intracranial hypertension. The medical awareness of hydrocephalus Chinese medicine practitioners believe that the disease mainly due to insufficient fetal endowment, Shenqi losses caused by serious illness or after a long illness, depletion of Kidney-yin; or acquired disorders, Spleen wet Pan, hepatitis, inflammation, myeloid Reduqing Obstructing plot that water from the brain Tongxinluo . Its place in brain disease, often spread to the heart, liver, spleen, kidney, and so on. The clinical diagnosis of hydrocephalus (1) the rapid growth of the skull and its morphological changes, the former囟expand or protruding. Expansion scalp vein, headache (slit in the skull has been more prominent autistic children). There will be advanced to the bottom of the eyeball, and the exposed upper sclera, commonly known as "sunset Xishan" levy. (2) and see convulsion, strabismus, paralyzed limbs, ataxia, mental stunting, and so on. (3) the head heard and "broken pots" The Sound of tendon reflexes hyperthyroidism or weakened limbs spasticity to lower extremities more obvious. (4) intraventricular injection of phenol red (neutral) 1 mL, 20 minutes after lumbar puncture to check cerebrospinal fluid color, two hours after the search of phenol red urine content to the clinical differential hydrocephalus typing. Hydrocephalus modern diagnostic equipment (1) skull X-ray: Visibility expanded thinning of the skull, cranial seam separation. (2) ventricular angiography: intraventricular injection of oxygen or lipiodol for X-ray, can understand the extent of ventricular expand, whether space-occupying lesions, blocking the site, and whether a traffic hydrocephalus. This inspection is quite dangerous, and should act with caution. (3) CT or MRI: brain ventricle water system that significantly expanded, sometimes expanded or part of the whole ventricle ventricle system expanded significantly thinner brain parenchyma; external hydrocephalus CT films have five performance: the amount and the amount of roof District subarachnoid increased other regional subarachnoid not wide; ago hemisphere inter crack widened; basement pool increased frontoparietal region cerebral sulcus deepening, widening; little or mild ventricular expansion. The inspections can accurately measuring ventricular size and the thickness of the brain tissue, the site of obstruction, whether space-occupying lesions and whether a traffic hydrocephalus. After review can understand ventricular shunt location and narrow, diagnosis and surgical treatment of the estimates are of important significance.
