Summary

In this study we explore To explore the role of maternal serum vascular endothelial growth factor (VEGF) in pregnancies complicated by foetal growth restriction.

Detailed description

Small-for-gestational age (SGA) is defined as an estimated foetal weight (EFW) or abdominal circumference (AC) less than the 10th centileand severe SGA as an EFW or AC less than the 3rd centile. Foetal Growth Restriction refers to failure of the foetus to achieve its predetermined growth potential for various reasons.Foetus with foetal growth restriction (FGR) greatly contributes to perinatal mortality and short- and long-term morbidity. There is a 3-10 fold increase in perinatal mortality in pregnancies complicated by this FGR .The incidence of FGR in newborns ranges between 3 and 7% of the total population .FGR is thought to stem from placental hypoxia-induced vasoconstriction of the fetoplacental vessels, leading to placental hypoperfusion and thus fetal undernutrition. However, the effects of hypoxia on the fetoplacental vessels have been surprisingly little studied.Vascular endothelial growth factor (VEGF) is one of the factors that take part in placental angiogenesis. It is highly expressed during embryonic and foetal development..Angiogenesis involves the branching of new microvessles from pre-existing larger blood vessels.Angiogenesis plays a role in the development of the villous vasculature and the formation of terminal villi in human placenta. IUGR occurs as a result of the failure of elongation, branching and dilatation of the capillary loops and of terminal villous formation.

Conditions

• Foetal Growth Restriction

Interventions

Type	Name	Description
DEVICE	obstetric Ultrasound	Transabdominal ultrasound was performed to confirm foetal number, viability, gestational age, exclusion of congenital anomalies, and assessment of amniotic fluid index and localization of the placenta.
OTHER	serum Vascular Endothelial Growth Factor	Maternal blood samples (10 cc) were taken from an antecubital vein. Plastic clean sterile tubes were used for collection of blood. Two cc of the blood sample were put in other clean sterile tubes containing ethylene diamine tetra-acetic acid (EDTA) to be used in measuring maternal hemoglobin concentrations and evaluating the complete blood count. The rest of maternal blood samples were centrifuged within 3 hours and sera collected equally in 2 suitable containers and stored at -80 degrees until assayed (first container for routine laboratory investigations and the second for VEGF assay).VEGF sample was allowed to clot for 30 minutes before centrifugation for 15 minutes. Serum is removed and assay immediately or sample was stored at -80 degrees
