Infection is a common complication that normally affects pediatric patients because they have not yet built up immunities to a number of different diseases. Normally, the incidence of infection decreases as the patient grows older and the body gains immunity to various infectious agents. [10] Shunt infection can occur in up to 27% of patients.
It is typically caused by a basilar skull fracture, which presents complications such as infection. It may be diagnosed using brain scans (prompted based on initial symptoms), and by testing to see if discharge from the nose is cerebrospinal fluid. Treatment may be conservative (as many cases resolve spontaneously), but usually involves ...
Cerebrospinal fluid is produced by the choroid plexus in the ventricles of the brain and contained by the dura and arachnoid layers of the meninges. [23] [42] [64] The brain floats in CSF, which also transports nutrients to the brain and spinal cord. As holes form in the spinal dura mater, CSF leaks out into the surrounding space.
Ashman beats are described as wide complex QRS complexes that follow a short R-R interval preceded by a long R-R interval. [3] This short QRS complex typically has a right bundle branch block morphology and represents an aberrantly conducted complex that originates above the AV node, rather than a complex that originates in either the right or left ventricle.
The revision of a shunt means to replace or make adjustments to all or part of the shunt, this also means that the location of the shunt may be changed therefore changing the category or type of shunt a patient has. For some patients with shunts, a revision or multiple revisions to the shunt may be required. This can be something minor, such as ...
Brain abscess (or cerebral abscess) is an abscess within the brain tissue caused by inflammation and collection of infected material coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote (lung, heart, kidney etc.) infectious sources.
A cerebral AVM is an abnormal anastomosis (connection) between the arteries and veins in the brain due to the lack of a capillary bed, and are most commonly of prenatal origin. [ 10 ] [ 11 ] In normal cerebral circulation , oxygen-enriched blood from the heart travels in sequence through smaller blood vessels going from arteries, to arterioles ...
Advancements have also been made which allow earlier management for common complications of cerebellar stroke such as brainstem compression and hydrocephalus. [4] Research is still needed in the area of cerebellar stroke management; however, several factors may lead to poor outcomes in individuals who have a cerebellar stroke. These factors ...
