cerebral ventricle

Ventriculostomy is a neurosurgical procedure that involves creating a hole ("ostomy") within a cerebral ventricle for drainage.

Walker and Blackfan discovered where cerebrospinal fluid originated by tracking dye injected into the cerebral ventricle of a dog.

At day thirteen, an ultrasound of his head showed a hemorrhage adjacent to his cerebral ventricles, the cisterns in the brain where cerebral-spinal fluid flows.

Ultrasonography demonstrated fetal hydrops, diaphragmatic hernia, and striking dilatation of the cerebral ventricles in both infants.

Cerebral palsy (periventricular leukomalacia) is caused by damage to developing oligodendrocytes in the brain areas around the cerebral ventricles.

Computed Tomography (CT) studies have found that the cerebral ventricles expand as a function of age, and this process is known as ventriculomegaly.

Kocher's point is a common entry point for an intraventricular catheter to drain cerebral spinal fluid from the cerebral ventricles.

The appearance of clear cerebrospinal fluid in the needle hub confirmed correct placement of the needle in the lateral cerebral ventricle.

The cranial pia mater joins with the ependyma which lines the cerebral ventricles to form choroid plexuses that produce cerebrospinal fluid.

Damage to the developing oligodendrocytes near the cerebral ventricles causes cerebral palsy as well as other demyelinating diseases such as multiple sclerosis and leukodystrophies.

Other types of defects of the brain such as microcephaly, polymicrogyria, porencephalic cysts and enlarged cerebral ventricles due to hydrocephalus are also common in Aicardi syndrome.

And, as with birds and rodents, cells from the lining of the cerebral ventricles in humans could be cultured in the laboratory and made to generate new neurons.

The fluid-filled cerebral ventricles (lateral ventricles, third ventricle, cerebral aqueduct, fourth ventricle) are also located deep within the cerebral white matter.

Normal pressure hydrocephalus (NPH) is a particular form of communicating hydrocephalus, characterized by enlarged cerebral ventricles, with only intermittently elevated cerebrospinal fluid pressure.

He became known in the medical community around the world for inventing several new procedures in brain surgery, including drainage of the cerebral ventricles and removals of large brain tumors.

Choroid plexus cells line the cerebral ventricles, form the blood-CSF barrier, and are responsible for the production of cerebrospinal fluid (CSF) [ 43 ] .

Classified as a sensory circumventricular organ (along with the SFO and AP), the OVLT is situated in the anterior wall of the third cerebral ventricle.

Hydrocephalus, post-traumatic ventricular enlargement, occurs when CSF accumulates in the brain, resulting in dilation of the cerebral ventricles and an increase in ICP.

Treatment involves monitoring of intracranial pressure (the pressure within the skull), draining of fluid from the cerebral ventricles, and, if an intracranial hematoma is present, draining of the hematoma.

This map can be seen as series of columns on the surface of the cerebral ventricles that after migrating to the cortex end up in the same orderly arrangement as the units in which they originated.

Dandy also observed that air introduced into the subarachnoid space via lumbar spinal puncture could enter the cerebral ventricles and also demonstrate the cerebrospinal fluid compartments around the base of the brain and over its surface.

In the first CT scan study in 1976 Crow and colleagues at Northwick Park demonstrated that there are structural changes (e.g. a degree of enlargement of the cerebral ventricles) in individuals who have suffered from schizophrenia.

Schizencephaly is a rare developmental disorder of brain characterized by abnormal continuity of histologic grey matter tissue extending from the ependyma lining of the cerebral ventricles to the pial surface of the cerebral hemisphere surface.

Hydrocephalus ex vacuo also refers to an enlargement of cerebral ventricles and subarachnoid spaces, and is usually due to brain atrophy (as it occurs in dementias), post-traumatic brain injuries and even in some psychiatric disorders, such as schizophrenia.

It involves the placement of a ventricular catheter (a tube made of silastic), into the cerebral ventricles to bypass the flow obstruction/malfunctioning arachnoidal granulations and drain the excess fluid into other body cavities, from where it can be resorbed.
