Comparison of Extravillous Intermediate Trophoblast Invasion Depth and Distribution Pattern Between Placenta Accreta and Non-Accreta.

BACKGROUND Placenta accreta spectrum (PAS) is a complex obstetric complication that poses a major risk for life-threatening hemorrhage. The pathogenesis of PAS is known to be related to placentogenesis, trophoblastic cells invasion, and previous obstetrical procedures that cause uterine wall defects. However, the precise mechanism of this disease has not been fully explained.

Difference of concentration of placental soluble fms-like tyrosine kinase-1(sFlt-1), placental growth factor (PlGF), and sFlt-1/PlGF ratio in severe preeclampsia and normal pregnancy.

Background: Placental soluble fms-like tyrosine kinase-1 (sFlt-1) which is an antagonist of vascular endothelial growth factor and placental growth factor (PIGF), is considered as one of etiology factors cause endothelial damage in preeclampsia due to increase of sFlt-1 level that change vascular endothelial integrity. This study aims to analyze the difference of sFlt-1 and PlGF concentration in severe preeclampsia and normal pregnancy, and the correlation between both in occurrence of severe preeclampsia.

Method: This is case control study involving 18 subjects with severe preeclampsia and 19 subjects with normal pregnancy as controls who met inclusion and exclusion criteria.

Correlation between cell-free mRNA expressions and PLGF protein level in severe preeclampsia.

Background: Preeclampsia is a major cause of morbidity and mortality, both maternal and perinatal. The etiology and pathophysiology of preeclampsia remain unknown. Research shows the implantation of the placenta in preeclampsia occurs due to incomplete angiogenic imbalance as one of the preeclampsia pathogenesis.
