Sonography as a procedure complementary to alpha-fetoprotein testing for neural tube defects
N. Slotnick, R. A. Filly, P. W. Callen and M. S. Golbus
Forty-four fetuses were studied sonographically because of an elevated amniotic fluid alpha-fetoprotein level noted during routine amniocentesis, questionable findings during an ultrasound examination at another institution, or a history of a neural tube defect in prior pregnancy. Eleven neural tube defects, 16 non-neural tube defect anomalies, and 17 normal fetuses were all correctly identified by sonography. Ultrasound answers the need for a second diagnostic tool to complement the alpha-fetoprotein measurement. |
