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).
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.
Neurosurgeons can use ShuntCheck flow results along with other diagnostic tests to assess shunt function and malfunction. [1] Hydrocephalus is a condition in which cerebrospinal fluid (CSF) accumulates in the brain, potentially leading to brain damage and death. It is corrected by a shunt which drains excess CSF from the brain to the abdomen.
The syndrome is related to cystic lesions and swelling of the third ventricle in the brain. Symptoms of bobble-head doll syndrome are diverse, including both physical and neurological symptoms. [1] The most common form of treatment is surgical implanting of a shunt to relieve the swelling of the brain. [2]
Pulmonary arteriovenous malformations are abnormal communications between the veins and arteries of the pulmonary circulation, leading to a right-to-left blood shunt. [5] [6] They have no symptoms in up to 29% of all cases, [7] however they can give rise to serious complications including hemorrhage, and infection. [5]
As soon as pulmonary pressure exceeds aortic pressure, shunt reversal (right-to-left shunt) occurs. [8] The upper extremity remains pink because deoxygenated blood flows through the patent duct and directly into the descending aorta while sparing the brachiocephalic trunk , left common carotid , and left subclavian arteries .
An uncorrected left-to-right shunt can progress to a right-to-left shunt; this process is termed Eisenmenger syndrome. [3] This is seen in Ventricular septal defect, Atrial septal defect, and patent ductus arteriosus, and can manifest as late as adult life. This switch in blood flow direction is precipitated by pulmonary hypertension due to ...
Brain abscess; Brain abscess in a person with a CSF shunt. The abscess is the darker gray region in the lower left of the image (corresponding to the right parietal lobe). The lateral ventricles are visible in black in the center of the brain, adjacent to the abscess. [1] Specialty: Neurology, infectious diseases
