Anencephaly Neural Tube Defects
MSAFP and ultrasound: Maternal serum Alpha fetoprotein at 16 weeks and detailed ultrasound at 18-20 weeks should detect fetal open neural tube defects with 96% accuracy. Closed neural tube defects are more difficult to diagnose but are more innocuous too. ...Read more
Physical exam: NTD's can form from one end of the nervous system to the other. The most common is spina bifida cystica with a sac of the inferior spinal cord and a skin opening near the lower end of the spine.Hidden defects in the area may be suspected on close exam. NTD at the neck can have a sac of neural tube coverings, Anencephaly, with an open skull is also obvious. ...Read more
How did you find out: Are you pregnant. or was it from reviewing your family history? Before pregnancy, the risk of an NTD can be reduced to the general population risk by taking 4 mg of folic acid daily before you know that you are pregnant. NTDs occur before a woman knows that she is pregnant,so starting folate then is shutting the barn door after the horse is gone. If pregnant, you require appropriate diagnostics ...Read moreSee 1 more doctor answer
If a sacral dimple is closed and is just a skin dimple, does this mean the child has a neural tube defect underneath?
Sacral dimple: Most of the time, sacral dimples are harmless and don't require any treatment. Rarely, a sacral dimple may indicate a serious underlying abnormality of the spine or spinal cord. To rule out any abnormality, your child's doctor may recommend an imaging test. If an abnormality is discovered, treatment depends on the underlying cause. ...Read moreSee 2 more doctor answers
In the 28w scan when they didnt get a clear shot of her spine the report said questionable sacrococcygeal open neural tube defect?
Get another scan: Scan quality varies with the equipment used and the experience of the tech.Some physicians spend most of their work day doing high resolution scans that are the most specific for determining what is going on.I would check with the OB and review the scan.See if a better scan is available or what else they can do to confirm what is going on. ...Read more
Tested positive for neural tube defects. I had a level 2 uktrasound done and everything was normal. Should I be worried still? Why did I test positive
Screening purpose: The purpose of screening is to find problems.You do so in steps.You use a less invasive test that is not as specific to narrow down the number of people getting the more invasive or expensive specific test.If I can screen 5000 people with test one and 100 come back suspicious, I can do step 2 on that 100 to find the 2 that are true problems. Any pregnancy can have an unexpected issue at some point ...Read more
Ultrasound, MSAFP.: Prenatal ultrasound should have >90% sensitivity for open neural tube defect detection around 20 weeks. Earlier (>16 weeks) risk stratification can occur with screening maternal blood for AFP - although that is not diagnostic and has to be followed by ultrasound for confirmation and/or differential diagnosis. Fetal MRI is used as part of evaluation for possible fetal surgery to treat spina bifida. ...Read moreSee 1 more doctor answer
NTD: Neural tube defects are a host of lesions that affect the spinal cord. They vary in degree from spina bifida occulta ( mildest ) to craniorrachischis totalis ( severest), spina bifida, and myelomengocele being the most frequently encountered. They have been linked to a diet deficient in folate (folic acid) during pregnancy. ...Read moreSee 1 more doctor answer
