Overview
Overview
Preeclampsia may be the result of placental factors in maternal circulation leading to endothelial dysfunction, hypertension, and proteinuria. Increased levels of an angiogenic factor named fms-like tyrosine kinase 1 in the placenta is correlated with endothelial dysfunction. In villous trophoblast of preeclamptic women, apoptosis was considered. Following uteroplacental ischemia, and invasion spiral arteries by trophoblasts, releasing some angiogenic factors causes other organ involvement. Incomplete penetration in recessive or dominant genes was noticed in pathogenesis of preeclampsia.
Pathophysiology
Pathophysiology
- The pathogenesis of preeclampsia is characterized by the following :[1][2]
- Chronic uteroplacental ischemia[3]
- Genetic susceptibility
- Very-low-density lipoprotein toxicity
- Increased trophoblast apoptosis or necrosis[4]
- Increased Maternal inflammatory response to fetal trophoblast
- Imbalance of angiogenic factors [5]
- Imbalance of prostacycline and thromboxan-A2
