Sildenafil Versus Low Molecular Weight Heparin in Fetal Growth Restriction Treatment
- Conditions
- Fetal Growth AbnormalityFetal Growth Restriction
- Interventions
- Drug: low molecular weight heparin
- Registration Number
- NCT03230162
- Lead Sponsor
- Ain Shams University
- Brief Summary
comparing the effect of using sildenafil citrate and LMWH in treatment of cases of IUGR due to placental insufficiency
- Detailed Description
One hundred pregnant women with documented intrauterine growth restriction due to placental insufficiency at 28-35 weeks of gestation will be distributed into two groups:
* Group S: 50 women will receive Sildenafil citrate 25 mg tab 3 times daily.
* Group H: 50 women will receive single dose of LMWH subcutaneous daily.
Both groups will undergo strict fetal surveillance in the form of:
Umbilical artery Doppler (UAD) is the primary surveillance tool in the FGR fetus:
middle cerebral artery (MCA) Doppler, ultrasound for (AC, EFW, and deepest vertical pocket (DVP) for amniotic fluid) and non stress test and Biophysical profile (BPP)
