The most common associated disorder is pre-eclampsia, affecting approximately 7% of all births. It is characterized by a failure of the cytotrophoblast to invade the uterus and its vasculature, specifically the spiral arteries that the endovascular cytotrophoblast should invade. The result of this is decreased blood flow to the fetus which may cause intrauterine growth restriction. Clinical symptoms of pre-eclampsia in the mother are most commonly high blood pressure, proteinuria and WebAn invasive nonvillous cytotrophoblast cell lesion is called GTN.
