Sildenafil Versus Low Molecular Weight Heparin in Fetal Growth Restriction Treatment

Phase 3
Conditions
Fetal Growth Abnormality
Fetal 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)
