Abstract
Three-dimensional sonography (3D US) has been demonstrated to be a promising technique for detecting fetal malformations. It is now clear that in the near future 3D technology will be present on all ultrasound machines. 3D US can be a powerful adjunctive tool to 2D US in providing a more comprehensible 3D US impression of congenital anomalies. Although there are still some problems like surface rendering in oligohydramnios and movement artifacts during volume acquisition that need to be resolved, three-dimensional ultrasound opens-up a new dimension in ultrasound investigation. ( Yigiter A. B., Kavak Z. N., 2007).
The present study was conducted at the period starting from January 2010 to November 2010 In Obstetrics and Gynecology department, Benha university hospital.
30 patients in the first half of pregnancy who have one or more risk factor which increases the incidence of occurrence of fetal congenital anomalies as age above 35 years old, Consanguinity, Diabetes mellitus, special habits e.g. (smoking, alcohol intake), X-ray exposure, any medications taken early in pregnancy, past history of delivery of malformed baby and family history of congenital anomalies were recruited to undergo 3D US in this prospective study.
The current study was done to demonstrate that 3D ultrsound can be an effective and early way for detection of fetal congenital anomalies, identifying fetal gender also in measuring nuchal translucency for prdetection of any chromosomal abnormalities.
The study showed that the mean age of the women was 30.7, also the mean parity among them was 2.2, and the mean gestational age was12.7.
The current study showed that 3D ultrsound can be an effective and early way for detection of fetal congenital anomalies. As we identifying two cases of congenital anomalies one case with omphalocele at 13 weeks+5 days and the other with cystic hygroma at 14 weeks. The mean N.T among the study group was 2.3mm and increased to 4mm in woman showing cystic hygroma. Fetal gender prediction in the study was 70 % of cases.
