Laboratory studies:
the estimation of maternal serum alpha-fetoprotein, are they blood samples from the mother in the second trimester of pregnancy ifthe fetus has spina bifida and markers increase by 75% compared to normal
alpha-fetoprotein-evaluation and evaluation byamniocentesis-specific enzyme acetylcholinesterase nerve
urinoanalizei-making, urine culture, assessment of creatinine, ureato check kidney function.
Imaging Studies:
Fetal ultrasound screening test is the first neural tube defects. It is used in week 10 of pregnancy. Procedure avoid the 1% risk of miscarriage after amniocentesis. 90% of neural tube defects aredetected until week 20 of pregnancy. Spina bifida is detected in the scanning head to subtle changes in the patterns of fetal skulland brain. Diagnosis is safe when three elements are presentclassic concavity frontal bones, and ventriculomegalia Chiari IImalformation. Defect level can not be clearly established by thestudy. 3D and 4D ultrasound can improve the accuracy of determining the level of the lesion.
Neuroimaging studies include magnetic resonance and computedtomography to detect comlicatiile neurological hidrocefalus.
Spine radiograph brings information to assess child born withspina bifida.
Cistograma is an anatomical study to obtain information on thebladder, urinary tract infection and vesicoureteral reflux present.
