Spina Bifida Flashcards
What is spina bifida?
A condition that refers to a developmental defect of the spinal column in which the arches of one or more of the spinal vertebrae fail to fuse
Failure of closure in the midline or lower end of the neural tube
when does spina bifida occur?
This process is usually complete by the 28th day of pregnancy
If problems occur during this process, the result can be brain disorders called neural tube defects including spina bifida
What is the most common type of spina bifida
occulta Approx 40% of all Americans may have spina bifida occulta, but because they experience little or no symptoms, very few of them ever know they have it
Why do some people not know they have it?
because they experience little or no symptoms, very few of them ever know they have it Is the mildest and most common form in which one or more vertebrae are malformed
The name occulta means
hidden indicates that the malformation or opening in the spine is covered by a layer of skin
occultas prognosis
This form of spina bifida rarely causes disability or symptoms
What is Cystica
Closed neural tube defects make up for this type of
spina bifida
This form consists of a diverse group of spinal defects in which the spinal cord is marked by a malformation of fat, bone, or membranes
What are the symptoms for Cystica
In some patients there are few or no symptoms; in others the malformation causes incomplete paralysis with urinary and bowel dysfunction
2 types of Cystica
Meningocele- where the meninges protrude through the defect (4%) may have few or no symptoms others may experience symptoms similar to closed neural tube defects
Myelomeningocele- elements of the cord also protrude through the defect, resulting in severe neural deficits (96%)1 out of 1,000 births. Spinal cord is exposed through the opening in the spine, resulting in partial or complete paralysis of the parts of the body below the spinal opening
Myelomeningocele affects ambulatory how ambulation
The paralysis may be so severe that the affected individual is non-ambulatory and may have urinary and bowel dysfunction
Complications with Myelomeningocele
hydrocephalus May need a shunt May develop menigitis, May develop learning disabilities May also suffer from latex allergies, skin problems, urinary tract infections, skin problems, urinary tract infections, gastrointestinal disorders, seizure disorders, depression and social and emotional problems
What is hydrocephalus?
disease that occurs when there is a build up of CNS fluid inside the brain that occurs when normal circulation is obstructed because the open spine permits the lower portion of the brain to slip through the opening of the spinal cord
Skull is stretched
Damages brain cells
Causes of Spina Bifida
Genetics and environemental factors Low folic acid consumption during pregnancy
Risk Factors
Hispanics and whites of European descent Family history Diabetes: Obesity: Increased body temperature
When to seek medical attention?
Before pregnancy
During pregnancy
Right after pregnancy
When the doctor feels it’s necessary
