When catheter drainage is permanent, it is usually referred to as a shunt. There are many catheter-based ventricular shunts that are named for where they terminate, for example, a ventriculoperitoneal shunt terminates in the peritoneal cavity, a ventriculoatrial shunt terminates within the atrium of the heart, etc.
An EVD is a flexible plastic catheter placed by a neurosurgeon or neurointensivist and managed by intensive care unit (ICU) physicians and nurses. The purpose of external ventricular drainage is to divert fluid from the ventricles of the brain and allow for monitoring of intracranial pressure. An EVD must be placed in a center with full ...
A cerebral shunt is a device permanently implanted inside the head and body to drain excess fluid away from the brain. They are commonly used to treat hydrocephalus, the swelling of the brain due to excess buildup of cerebrospinal fluid (CSF).
Keen's point is one of the ventriculostomy sites used in neurosurgery, typically in pediatrics for ventriculoperitoneal shunt placement. Keen's point is located 3 cm superior and 3 cm posterior to the helix of the ear.
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 ...
A Peritoneovenous shunt: (also called Denver shunt) [2] is a shunt which drains peritoneal fluid from the peritoneum into veins, usually the internal jugular vein or the superior vena cava. It is sometimes used in patients with refractory ascites. It is a long tube with a non-return valve running subcutaneously from the peritoneum to the ...
Seven other patients were injected through ventriculoperitoneal shunts. These seven patients were being treated for varying neurodegenerative disorders including Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), progressive multiple sclerosis (MS-P), Parkinson's , spinal cord injury , traumatic brain injury , and stroke.
Getting the ventricles smaller, is the initial step, stabilising them is the second step before placing a shunt – which is the final step in therapy. Any variation from this formula can lead to an ineffective, yet patent shunt system, despite a low-pressure setting.
