One of the common causes of subdural hygroma is a sudden decrease in pressure as a result of placing a ventricular shunt. This can lead to leakage of CSF into the subdural space especially in cases with moderate to severe brain atrophy. In these cases, symptoms such as mild fever, headache, drowsiness and confusion can be seen, which can be ...
10–15% of intracranial AV malformations are DAVFs. [4] There is a higher preponderance in females (61–66%), and typically patients are in their fourth or fifth decade of life. DAVFs are rarer in children. [2]
Infection is a common complication that normally affects pediatric patients because they have not yet built up immunities to a number of different diseases. Normally, the incidence of infection decreases as the patient grows older and the body gains immunity to various infectious agents. [10] Shunt infection can occur in up to 27% of patients.
For example, it may be required for a patient with a lumbar–peritoneal shunt, if multiple revisions are required or overdrainage is occurring, to have it replaced with a ventriculo–peritoneal shunt (VP shunt). Shunt revisions are required due to the following complications: Over drainage; Under drainage; Infection; Blockage or obstruction
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
Surgical placement of a cerebral shunt: [25] An internal shunt drains into the subdural compartment. [26] A cystoperitoneal shunt drains to the peritoneal cavity. [27] Fenestration: Craniotomy with excision [28] Various endoscopic techniques are proving effective, [29] including laser-assisted techniques. [30] Drainage by needle aspiration or ...
A cerebral AVM is an abnormal anastomosis (connection) between the arteries and veins in the brain due to the lack of a capillary bed, and are most commonly of prenatal origin. [ 10 ] [ 11 ] In normal cerebral circulation , oxygen-enriched blood from the heart travels in sequence through smaller blood vessels going from arteries, to arterioles ...
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]
