What does ex vacuo dilatation of the ventricles mean?
Hydrocephalus ex-vacuo occurs when a stroke or injury damages the brain and brain matter actually shrinks. The brain may shrink in older patients or those with Alzheimer’s disease, and CSF volume increases to fill the extra space. In these instances, the ventricles are enlarged, but the pressure usually is normal.
What is ex vacuo phenomenon?
Abstract. CSF ex vacuo is a proposed designation for abnormal collections of CSF replacing brain tissue which is absent or has disappeared as a result of maldevelopment, injury, infection, vascular disturbances, brain atrophy, etc.
What is the life expectancy of hydrocephalus?
What is the life expectancy of a child who has hydrocephalus? Children often have a full life span if hydrocephalus is caught early and treated. Infants who undergo surgical treatment to reduce the excess fluid in the brain and survive to age 1 will not have a shortened life expectancy due to hydrocephalus.
Is hydrocephalus ex vacuo communicating?
Communicating hydrocephalus can also be subdivided into: normal pressure hydrocephalus (NPH) hydrocephalus ex-vacuo.
Can a baby with hydrocephalus walk?
Many children with pediatric hydrocephalus have normal intelligence and physical development, but some may be slower to develop skills such as hand-eye coordination or learning to walk. Some may experience learning problems as they progress in school.
How quickly does NPH progress?
Studies show that 50 to 80% of patients can expect improvement of their symptoms in the first 2 to 3 years [1]. Other patients may have a less successful outcome. Several factors determine the outcome, including the patient’s overall health, what caused the NPH to occur, and how long the patient has had NPH.
What is hydrocephalus ex vacuo?
Hydrocephalus ex vacuo, also known as compensatory enlargement of the CSF spaces , is a term used to describe the increase in the volume of CSF, characterized on images as an enlargement of cerebral ventricles and subarachnoid spaces, caused by encephalic volume loss. On this page:
Is there more CSF in hydrocephalus ex-vacuo?
Although there is more CSF than usual, the CSF pressure itself is normal in hydrocephalus ex-vacuo. Hydrocephalus is an abnormal buildup of cerebrospinal fluid (CSF) in the ventricles of the brain. The fluid is most often under increased pressure and that pressure can compress and damage the brain.
What causes hydrops fetalis?
Severe swelling can interfere with how the body organs work. Nonimmune hydrops fetalis occurs when a disease or medical condition disrupts the body’s ability to manage fluid. There are three main causes for this type: heart or lung problems, severe anemia ( thalassemia ), and genetic defects, including Turner syndrome.
What is Rh compatibility and nonimmune hydrops fetalis?
Rh compatibility causes massive red blood cell destruction, which leads to several problems, including total body swelling. Severe swelling can interfere with how the body organs work. Nonimmune hydrops fetalis occurs when a disease or medical condition disrupts the body’s ability to manage fluid.
