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).
It is done by surgically penetrating the skull, dura mater, and brain such that the ventricular system ventricle of the brain is accessed. When catheter drainage is temporary, it is commonly referred to as an external ventricular drain (EVD). When catheter drainage is permanent, it is usually referred to as a shunt.
Cardiac shunts may be described as right-to-left, left-to-right or bidirectional, or as systemic-to-pulmonary or pulmonary-to-systemic.; Cerebral shunt: In cases of hydrocephalus and other conditions that cause chronic increased intracranial pressure, a one-way valve is used to drain excess cerebrospinal fluid from the brain and carry it to other parts of the body.
Cerebrospinal fluid diversion is a procedure that is used to drain fluid from the brain and spinal cord. A shunt is placed in a ventricle of the brain and threaded under the skin to another part of the body, usually the abdomen. It is used to treat hydrocephalus and idiopathic intracranial hypertension.
The brain can swell due to pressure build up in the ventricles and permanent brain damage can occur. Physicians or nurses may have to adjust or flush these small diameter catheters to manage medical tube obstructions and occlusions at the intensive-care bedside.
