1 PRENATAL ULTRASONOGRAPHIC EVALUATION OF MULTIPLE GESTATIONS IN NIGERIAN WOMEN IN NATIONAL HOSPITAL, ABUJA
Multifoetal gestations present a serious public health challenge due to its unique complications. Research findings in this regard especially in the setting of this study are scarce. The adoption of prenatal ultrasound for this study is because it is safe, available and does not employ ionising radiation.
An initial 500 which was increased to 2,000 consenting patients but which reduced to 1989 due to attrition were scanned twice (after 10weeks GA and from 28weeks GA) over a 2 year period. The initial increase was to improve the power of the findings. 85 patients had multiple gestations.
The prevalence rate was 4.3% with a rate of 41 per 1000 and 2 per 1000 deliveries in twin and triplets respectively. Increasing age, positive family history and fertility treatment were established predisposing factors to multiple pregnancies. 10 cases of foetal complications were observed. 8(80%) of these cases were found in patients on assisted reproductory treatment whereas 2(20%) were found in the naturally conceiving ones. The remaining 75 had no complications. Similarly, maternal complications occurred more in the patients on assisted reproductory treatment (51.8%) as against 48.2% in the latter group.
