Hydrocephalus & Shunt Glossary
 

 http://www.divideclassic.org/Documents/Hydroglossary.htm

 Arachnoid:  the middle layer of the meninges (covering the brain)

Atriumright chamber of the heart

Catheter (ventricular):  the tube of the shunt that enters the ventricle

Choroid Plexustissue in the ventricles that produce CSF

Contrast Materialdye injected into the blood or CSF for enhancement of imaging studies; helps abnormal tissue stand out

CSFcerebrospinal fluid

CVD:  continuous ventricular drainage; same as EVD

Dilated:  enlarged

Distal:  farthest away; opposite of proximal

Durathe outermost membrane of the meninges (covering of the brain)

Endoscopesurgical instrument that allows visualization into the ventricles

EVDexternal ventricular drainage system drains CSF outside of the body; same as CVD

Gallbladder:  sac-like organ in the abdomen; shunts are occasionally placed here

Hematomacollection of blood; blood clot

Horns (of ventricles):  ends of the lateral ventricles:  frontal, temporal, occipital

Hydrocephalusimbalance between the production and absorption of CSF with high pressure within the brain

ICPintracranial pressure

LP:  lumbar puncture

Macrocephaly:  large head

Meninges:  membranes (3) that cover the brain and spinal cord

Microcephalysmall head

MRImagnetic resonance imaging

Peritoneal Cavityabdominal cavity containing omentum and other organs

Pia:  the innermost layer of the meninges (covering of brain)

Pleura:  lining around the lungs

Proximal:  closest part

Rickham Reservoirchamber in the shunt between the ventricular catheter and the valve

Sagittal:  plane of reference that divides the head into right and left halves

Shuntogram:  an imaging study with contrast to assess shunt function

Shunt Seriesan x-ray study to assess the connections of the shunt parts and placement of the distal catheter tip

Shunt Tap:  a small needle inserted into the shunt reservoir or valve to collect CSF or measure ICP

 Silastic:  soft rubbery plastic used to make most shunt materials

Subarachnoid:  between the pia and arachnoid meninges

Subduralbetween the dura and arachnoid meninges

Third Ventriculostomy:  a hole surgically created between the 3rd ventricle and subarachnoid space for drainage of CSF

VA:  ventriculoatrial

VPventriculoperitoneal or ventriculopleural

Valve:  the part of the shunt that regulates the outflow resistance of CSF

Ventricles:  cavities within the brain that contain CSF; there are 4 ventricles 2 lateral, third and the fourth

Ventriculomegalylarge ventricles

Ventriculostomy:  a catheter in a ventricle that drains CSF outside of the body
