Brain Injury due to Ventricular Shunt Placement Delineated by Diffusion Tensor Imaging (DTI) Tractography

Abstract

Recovery of motor function after serious injury to motor cortex during childhood is a dramatic example of the plasticity of the child's brain to injury. In addition, we suggest that the behavioral disorder that emerged in this patient may be related to limbic system injury suffered during the shunt revision.

Injury of leg somatotopy of corticospinal tract at corona radiata by ventriculoperitoneal shunt

“…Since the introduction of DTI, several studies have reported on injuries of various neural tracts in the brain following shunt surgery. [ 5 – 8 ] In 2008, Gold et al, [ 8 ] based on DTT results, reported on a patient who presented with direct injury of almost the entire CST and limbic system following revision of a VP shunt. In 2015, Jang and Seo [ 6 ] reported on a patient that developed hemiparesis and gait difficulty after VP shunt, and injuries of a corticoreticulospinal tract and the anterior portion of a CST were detected on DTT.…”

“…[ 4 ] A few previous studies using DTT have demonstrated injury of neural tracts including the corticospinal tract (CST), the superior longitudinal fasciculus and cingulum, and the corticoreticulospinal tract following shunt surgery. [ 5 – 8 ] Further detailed description of such injury is useful in the management of patients following shunt operation.…”

Injury of the thalamocingulate tract in the Papez circuit by ventriculoperitoneal shunt: A case report

“…[1][2][3][4] The Papez circuit, described by James Papez in 1937, is involved in memory function, particularly episodic memory. 5 The thalamocingulate tract (TCT), a part of the Papez circuit, is located between the anterior thalamic nuclei and the cingulate gyrus.…”

The Safe Area in the Parieto-Occipital Lobe in the Human Brain: Diffusion Tensor Tractography

“…I nvasive neurological interventions could often result in neural injury of the brain (4,8,14,21,25). These interventions comprise the operation, procedures of the shunt operation, radiotherapy, or radiosurgery (4,8,14,21,25).…”

“…These interventions comprise the operation, procedures of the shunt operation, radiotherapy, or radiosurgery (4,8,14,21,25). These interventions have been performed based on known neuroanatomy or experience (5).…”
